It has a mixed economy, and it ranks above the US and most European nations on the Heritage Foundation's index of economic freedom. Canada's economy is dominated by the service industry, but it enjoys a rich natural resource cpr144449003101 sector as well. Canada is a large exporter of agricultural resources as well as gold, nickel, aluminum and lead. Canada is the largest producer of zinc and uranium, and thanks to its rich oil sands reserves, natural gas deposits and hydroelectric capacity, it is one of the few nations that are net energy exporters.

.ca Domains Dispute & Policy

Last Update 20 August 2012. The most current .ca domains dispute policy can be found at: www.cira.ca/assets/Documents/Legal/Dispute/CDRPpolicy.pdf

CIRA Domain Name Dispute Resolution Policy
Version 1.3 (August 22, 2011)


1.1 Purpose. The purpose of this CIRA Domain Name Dispute Resolution Policy
(the “Policy”) is to provide a forum in which cases of bad faith registration of domain names registered in the dot-ca country code top level domain name registry operated by CIRA (the “Registry”) can be dealt with relatively inexpensively and quickly.
1.2 Scope. The Policy sets forth the terms and conditions for resolution by arbitration of a dispute between a person (the “Registrant”) who has obtained the registration of a domain name in the Registry (the “Registration”) and any other person (other than CIRA or a CIRA certified registrar (a “Registrar”) acting in its capacity as Registrar) concerning the registration of the domain name. For the purposes of this Policy, “domain name” means the domain name excluding the “dot-ca” suffix and the suffixes associated with all third and fourth level domain names accepted for registration by CIRA.
1.3 Rules. A dispute resolution proceeding initiated under the Policy (a “Proceeding”) is also subject to the CIRA Dispute Resolution Rules (the “Resolution Rules”).
1.4 Eligible Complainants. The person initiating a Proceeding (the “Complainant”) must, at the time of submitting a complaint (the “Complaint”), satisfy the Canadian
Presence Requirements for Registrants (the “CPR”) in respect of the domain name that is the subject of the Proceeding unless the Complaint relates to a trade-mark registered in the Canadian Intellectual Property Office (“CIPO”) and the Complainant is the owner of the trade-mark.
1.5 Dispute Resolution Service Provider. All Proceedings will be administered by a dispute resolution service provider approved by CIRA (the “Provider”).
1.6 Role of CIRA. CIRA will not participate in any way in any Proceeding other than as expressly provided in the Policy and the Resolution Rules.
1.7 Alternative Proceedings. The availability of a Proceeding pursuant to the Policy will not prevent either the Registrant or the Complainant from submitting a dispute between them to a judicial or administrative proceeding, arbitration, mediation or any other procedure at any time for independent resolution. However, unless otherwise agreed among the Complainant, the Registrant and the Provider, neither the Complainant nor the Registrant will take any action to cause or permit the provisions of any foreign or domestic legislation relating to arbitration of disputes to apply to the conduct of any Proceeding.
1.8 Amendments. CIRA reserves the right to amend the Policy at any time. Any amended Policy will become effective thirty (30) calendar days after the amended Policy is posted on CIRA’s website. The version of the Policy in effect at the time a Proceeding is initiated will apply to the Proceeding.
1.9 Commitments by Complainant. By initiating a Proceeding, the Complainant:
(a) agrees that the Complainant will be bound by the provisions of the Policy and the Resolution Rules; and
(b) represents and warrants to CIRA and the Registrant that: (i) the Complainant satisfies the CPR at the time of submitting the Complaint or the Complaint relates to a trade-mark registered in CIPO and the Complainant is the owner of the trademark; and (ii) if CIRA transfers the Registration that is the subject of the Proceeding to the Complainant at the time of transfer, the Complainant, will satisfy the CPR in respect of the domain name that is subject of the Proceeding.


2.1 Initiation of Proceeding. A Proceeding is initiated by the submission of a Complaint by a Complainant with a Provider in accordance with the Resolution Rules.
2.2 Administration of Proceeding. The Provider will administer the Proceeding in accordance with the Policy and the Resolution Rules.
2.3 Fees. The fees charged by a Provider in connection with a Proceeding are set out in the Resolution Rules.
2.4 Restriction on Registration Transactions. Upon the receipt of notice by CIRA from a Provider of the submission of a Complaint to the Provider, unless otherwise permitted by the Policy, CIRA will not allow the Registration that is the subject of the Complaint to be deleted, or transferred to another person, and the Registration will be so marked in CIRA’s records.
2.5 Permitted Transactions. CIRA may suspend, delete or modify the Registration that is the subject of a Complaint in accordance with the terms of the agreement between the Registrant and CIRA concerning the Registration (the “Registrant Agreement”). After the date on which CIRA receives one of the communications or documents listed below, CIRA will delete the reference to the Proceeding in CIRA’s records and CIRA may allow the Registration to be deleted or transferred to another person:
(a) notice from the Provider that the Proceeding is concluded or terminated;
(b) appropriate written or electronic instructions from the Registrant’s Registrar to transfer the Registration to the Complainant, along with written or electronic instructions from the Registrant to CIRA confirming that they wish to transfer the domain name to the Complainant;
(c) a copy of an agreement executed by both the Registrant and the Complainant settling the Complaint; or
(d) a certified copy of an order, ruling, judgment or decision of a court, tribunal, board, administrative body or commission in Canada or an arbitrator disposing of the Complaint. CIRA will have the right but not the obligation to take any steps to verify the validity of the communication or document. If CIRA receives and accepts any of the above noted communications, CIRA will notify the Provider upon the execution of the deletion or transfer.


3.1 Applicable Disputes. A Registrant must submit to a Proceeding if a Complainant asserts in a Complaint submitted in compliance with the Policy and the Resolution Rules that:
(a) the Registrant’s dot-ca domain name is Confusingly Similar to a Mark in which the Complainant had Rights prior to the date of registration of the domain name and continues to have such Rights;
(b) the Registrant has no legitimate interest in the domain name as described in paragraph 3.4; and
(c) the Registrant has registered the domain name in bad faith as described in paragraph 3.5. For the purposes of this Policy, the date of registration of a domain name is the date on which the domain name was registered in the Registry or the predecessor registry operated by the University of British Columbia by the Registrant or a predecessor in title of the Registrant.
3.2 Mark. A cpr144449003101 “Mark” is:
(a) a trade-mark, including the word elements of a design mark, or a trade name that has been used in Canada by a person, or the person’s predecessor in title, for the purpose of distinguishing the wares, services or business of that person or predecessor or a licensor of that person or predecessor from the wares, services or business of another person;
(b) a certification mark, including the word elements of a design mark, that has been used in Canada by a person or the person’s predecessor in title, for the purpose of distinguishing wares or services that are of a defined standard;
(c) a trade-mark, including the word elements of a design mark, that is registered in CIPO; or
(d) the alphanumeric and punctuation elements of any badge, crest, emblem or mark in respect of which the Registrar of Trade-marks has given public notice of adoption and use pursuant to paragraph 9(1)(n) of the Trade-marks Act (Canada).
3.3 “Confusingly Similar”. In determining whether a domain name is “Confusingly Similar” to a Mark, the Panel shall only consider whether the domain name so nearly resembles the Mark in appearance, sound or the ideas suggested by the Mark as to be likely to be mistaken for the Mark.
3.4 Legitimate Interests. For the purposes of paragraphs 3.1(b) and 4.1(c), any of the following circumstances, in particular but without limitation, if found by the Panel to be proved based on its evaluation of all evidence presented, shall demonstrate that the Registrant has a legitimate interest in a domain name:
(a) the domain name was a Mark, the Registrant used the Mark in good faith and the Registrant had Rights in the Mark;
(b) the Registrant registered the domain name in Canada in good faith in association with any wares, services or business and the domain name was clearly descriptive in Canada in the English or French language of: (i) the character or quality of the wares, services or business; (ii) the conditions of, or the persons employed in, production of the wares, performance of the services or operation of the business; or (iii) the place of origin of the wares, services or business;
(c) the Registrant registered the domain name in Canada in good faith in association with any wares, services or business and the domain name was understood in Canada to be the generic name thereof in any language;
(d) the Registrant used the domain name in Canada in good faith in association with a non-commercial activity including, without limitation, criticism, review or news reporting;
(e) the domain name comprised the legal name of the Registrant or was a name, surname or other reference by which the Registrant was commonly identified; or
(f) the domain name was the geographical name of the location of the Registrant’s non-commercial activity or place of business. In paragraph 3.4(d) “use” by the Registrants includes, but is not limited to, use to identify a web site.
3.5 Registration in Bad Faith. For the purposes of paragraphs 3.1(c) and 4.1(b), any of the following circumstances, in particular but without limitation, if found by the Panel to be present, shall be evidence that a Registrant has registered a domain name in bad faith:
(a) the Registrant registered the domain name, or acquired the Registration, primarily for the purpose of selling, renting, licensing or otherwise transferring the Registration to the Complainant, or the Complainant’s licensor or licensee of the Mark, or to a competitor of the Complainant or the licensee or licensor for valuable consideration in excess of the Registrant’s actual costs in registering the domain name, or acquiring the Registration;
(b) the Registrant registered the domain name or acquired the Registration in order to prevent the Complainant, or the Complainant’s licensor or licensee of the Mark, from registering the Mark as a domain name, provided that the Registrant, alone or in concert with one or more additional persons has engaged in a pattern of registering domain names in order to prevent persons who have Rights in Marks from registering the Marks as domain names;
(c) the Registrant registered the domain name or acquired the Registration primarily for the purpose of disrupting the business of the Complainant, or the Complainant’s licensor or licensee of the Mark, who is a competitor of the Registrant; or
(d) the Registrant has intentionally attempted to attract, for commercial gain, Internet users to the Registrant’s website or other on-line location, by creating a likelihood of confusion with the Complainant’s Mark as to the source, sponsorship, affiliation, or endorsement of the Registrant’s website or location or of a product or service on the Registrant’s website or location.


4.1 Onus. To succeed in the Proceeding, the Complainant must prove, on a balance of probabilities, that:
(a) the Registrant’s dot-ca domain name is Confusingly Similar to a Mark in which the Complainant had Rights prior to the date of registration of the domain name and continues to have such Rights; and
(b) the Registrant has registered the domain name in bad faith as described in paragraph 3.5; and the Complainant must provide some evidence that:
(c) the Registrant has no legitimate interest in the domain name as described in paragraph 3.4.
Even if the Complainant proves (a) and (b) and provides some evidence of (c), the Registrant will succeed in the Proceeding if the Registrant proves, on a balance of probabilities, that the Registrant has a legitimate interest in the domain name as described in paragraph 3.4.
4.2 Decision and Amendment to a Decision. The panel appointed to decide the Proceeding (the “Panel”) will consider all the evidence presented in the Proceeding and will render its decision in accordance with the Policy and the Resolution Rules. The Panel may amend a decision pursuant to the Resolution Rules. The Panel shall be wholly responsible for the accuracy of the decision, the corrigendum, and any references therein. CIRA is not responsible for the decision and, if applicable, the corrigendum, and CIRA will not make any amendments to the decision.
4.3 Remedies. If the Panel decides in favour of the Complainant, the Panel will decide whether the Registration should be deleted or transferred to the Complainant.
4.4 Notice and Publication of Decision or Corrigendum. The Provider shall notify the Complainant, the Registrant, the Registrant's Registrar and CIRA of the Panel's decision or, if applicable, the corrigendum pursuant to the Rules. CIRA will, in accordance with the Rules, publish each decision in a Proceeding in full on CIRA's website.
4.5 Implementation of Decision. If a Panel decides in a Proceeding by way of its decision that a Registration is to be deleted or transferred, and CIRA is satisfied that the Complainant satisfies the CPR in respect of the domain name that is subject of the Proceeding, CIRA will implement the decision as soon as practicable but no sooner than thirty (30) days after the date on which CIRA is notified by the Provider that the Complainant, the Registrant, the Registrant’s Registrar have been notified by the Provider of the Panel’s decision. If the Panel decides that the Registration should be transferred, CIRA is not required to effect the transfer until the Complainant enters into a Registrant Agreement with CIRA. However, if during the thirty (30) day period, CIRA receives official documentation (such as a copy of a Notice of Action or Statement of Claim or like document) issued by a Canadian court that the Registrant has commenced a legal proceeding against the Complainant in respect of the domain name that is subject of the Proceeding, CIRA will not implement the Panel’s decision, and will take no further action until CIRA receives (i) evidence satisfactory to CIRA of a resolution between the parties; (ii) evidence satisfactory to CIRA that such proceeding has been dismissed or withdrawn; or (iii) a copy of an Order from such Court dismissing such proceeding or ordering that the Registrant does not have the right to continue using the domain name.
4.6 Bad Faith of Complainant. If the Registrant is successful, and the Registrant proves, on a balance of probabilities, that the Complaint was commenced by the Complainant for the purpose of attempting, unfairly and without colour of right, to cancel or obtain a transfer of any Registration which is the subject of the Proceeding, then the
Panel may order the Complainant to pay to the Provider in trust for the Registrant an amount of up to five thousand dollars ($5000) to defray the costs incurred by the Registrant in preparing for, and filing material in the Proceeding. The Complainant will be ineligible to file another Complaint in respect of any Registration with any Provider until the amount owing is paid in full to the Provider.


5.1 Limitation on Liability. In no event will CIRA, the Registrant’s Registrar, any Provider or their respective directors, officers, members, employees, agents or representatives, or any member or members of a Panel, be liable to a Registrant, a Registrant’s Registrar, a Complainant or any other person for any loss, damages or expense including, without limitation, any special, indirect, incidental, exemplary, punitive or consequential damages, or economic loss or damages resulting from loss of use, lost business revenue, lost profits or third party damages arising from or in any way connected with:
(a) the application of the Policy or the Resolution Rules by any of them;
(b) a decision or corrigendum rendered by a Panel in a Proceeding;
(c) CIRA’s compliance with any order, ruling, decision, corrigendum, or judgment made by a Panel in a Proceeding or by any court, tribunal, board, administrative body, commission or arbitrator; or
(d) any action taken or not taken by CIRA, the Registrant’s Registrar, a Provider or a Panel or a member of a Panel in consequence of the Resolution Rules or this Policy, including without limitation paragraph 5.1(a), 5.1(b) or 5.1(c).
5.2 Exception to Limitation. In no event is the limitation of liability set out in paragraph 5.1 intended to limit the liability of the Provider for the Provider’s gross negligence or willful misconduct or a member of a Panel for the member’s gross negligence or willful misconduct.
.ca Glossary of Technical Terms

A top-level domain devoted solely to international treaty organizations that have independent legal personality. Such organizations are not governed by the laws of any specific country, rather by mutual agreement between multiple countries. IANA maintains the domain registry for this domain.

A record
The representation of an IPv4 address in the DNS system.

AAAA record
The representation of an IPv6 address in the DNS system.

Administrative contact
Majority of the registries require 4 contacts for a successful domain registration: Registrant, Administrative, Technical and Billing. The Administrative contact is intended to represent the Registrant(owner) of the domain, in any non-technical matters, regarding the management of the domain. Certain extensions require Administrative contact to confirm requests and accept notices about the domain name.

The ASCII-compatible encoded (ACE) representation of an internationalized domain name, i.e. how it is transmitted internally within the DNS protocol. A-labels always commence the with the prefix "xn--". Contrast with U-label.

Originally a reference to the US Government agency that managed some of the Internet’s initial development, now a top-level domain used solely for machine-readable use by computers for certain protocols — such as for reverse IP address lookups, and ENUM. The domain is not designed for general registrations. IANA manages ARPA in conjunction with the Internet Architecture Board.

ASCII (American Standard Code for Information Interchange)
The standard for transmitting English (or "Latin") letters over the Internet. DNS was originally limited to only Latin characters because it uses ASCII as its encoding format, although this has been expanded using Internationalized Domain Names(IDN) for Applications.

Authoritative Name Server
A domain name server configured to host the official record of the contents of a DNS zone. Each Canadian .ca domain name must have a set of these so computers on the Internet can find out the contents of that domain. The set of authoritative name servers for any given domain must be configured as NS records in the parent domain.

Automatic Renewal
The service of automatic renewal allows the customers the convenience of automatic billing for the services ordered through the domain registrar. If the automatic renewal is selected, customer's credit card will be automatically charged for the service, which will avoid the interruption in service.

Billing Contact
Majority of the registries require 4 contacts for a successful domain registration: Registrant, Administrative, Technical and Billing. The Billing contact is responsible for the payment of the domain, and is usually assigned to the registrar managing the domain.

Caching Resolver
The combination of a recursive name server and a caching name server.

Cloaking Forwarding
Domains can be forwarded to another URL by using a forwarding service. Cloaking forwarding differs from Apache 301 forwarding by showing the content of the URL being forwarded to, however the URL bar displays the original domain name.

CNAME Record
A CNAME record is an abbreviation for Canonical Name record and is a type of resource record in the Domain Name System (DNS) used to specify that a domain name is an alias for another domain, the "canonical" domain. CNAME has a very specific syntax rule. CNAME can only be set up for the unique subdomain, meaning that it cannot be set up for any subdomain, which has already been set up for the domain. Thus CNAME is most commonly set up for WWW subdomain.

Country-code top-level domain (ccTLD)
A Class of Top Level Domains, generally assigned or reserved by a country, sovereign state, or territory. IANA is the organization, responsible for the ccTLD assignments. Since 2010 there 2 types of ccTLDs: 2 letter ASCII characters TLDs and IDN TLDs, which consist of the native language characters. Each country/territory is able to implement certain restrictions and requirements on the ccTLD assigned to them.

Cross-Registry Information Service Protocol (CRISP)
The name of the working group at the IETF that developed the Internet Registry Information Service (IRIS), a next-generation WHOIS protocol replacement.

Any transfer of responsibility to another entity. In the domain name system, one name server can provide pointers to more useful name servers for a given request by returning NS records. On an administrative level, sub-domains are delegated to other entities. IANA also delegates IP address blocks to regional Internet registries.

Deletion of the domain results in the domain record being removed from the registry's database. Domain deletion procedure and availability differs depending on each of the TLD's policy. Certain extensions require additional payment to delete a domain name.

DNS zone
A section of the Domain Name System name space. By default, the Root Zone contains all domain names, however in practice sections of this are delegated into smaller zones in a hierarchical fashion. For example, the .com zone would refer to the portion of the DNS delegated that ends in .com.

A technology that can be added to the Domain Name System to verify the authenticity of its data. The works by adding verifiable chains of trust that can be validated to the domain name system.

Domain lock
In order to prevent unwanted changed to the domain names, customers have an ability to change the locks on their domain names. The domain lock availability depends on individual TLD, and includes clientTransferProhibited, clientUpdateProhibited, clientDeleteProhibited, clientRenewProhibited.

Domain Name
A unique identifier with a set of properties attached to it so that computers can perform conversions. A typical domain name is "icann.org". Most commonly the property attached is an IP address, like "", so that computers can convert the domain name into an IP address. However the DNS is used for many other purposes. The domain name may also be a delegation, which transfers responsibility of all sub-domains within that domain to another entity. domain name label a constituent part of a domain name. The labels of domain names are connected by dots. For example, "www.iana.org" contains three labels — "www", "iana" and "org". For internationalized domain names, the labels may be referred to as A-labels and U-labels.

Domain Name Registrar
An entity offering domain name registration services, as an agent between registrants and registries. Usually multiple registrars exist who compete with each other, and are accredited. For most generic top-level domains, domain name registrars are accredited by ICANN.

Domain Name Registry
A registry tasked with managing the contents of a DNS zone, by giving registrations of sub-domains to registrants.

Domain Name Server
A general term for a computer hardware or software server, which answers requests to convert domain names into something else. These can be subdivided into authoritative name servers, which store the database for a particular DNS zone; as well as recursive name servers and caching name servers.

Domain Name System (DNS)
The global hierarchical system of domain names. A global distributed database contains the information to perform the domain name conversations, and the most central part of that database, known as the root zone is coordinated by IANA.

Dot or “."
Common way of referring to a specific top-level domain. Dot generally precedes the Top Level domain, such as dot com is written down as “.ca”.

Expiration date
The expiration date determines when the domain registration period ends. In order to avoid downtime for the domain, renewal of the domain at least two weeks before expiration date is strongly encouraged. After the expiration date passes, some registries maintain the record of the domain name under the same owner, however the DNS services are put on hold.

Extensible Provisioning Protocol (EPP)
A protocol used for electronic communication between a registrar and a registry for provisioning domain names.

Refers to the last portion of the domain name, located after the dot. Domain extension helps determine the registry, to which domain pertains, and allows to accurately classify the domain name.

First Come, First Served (FCFS)
Multiple applications for the same domain name are not accepted. The domain will be awarded to the first registrar who submits a registration request.

File Transfer Protocol does exactly what it says. The standard network protocol allows the transfer of files from one host to another. There are many FTP clients(programs) available, which allow you to connect to your host and transfer your completed content to your hosting provider's space.

Fully-Qualified Domain Mame (FQDN)
A complete domain name including all its components, i.e. "www.icann.org" as opposed to "www".

GAC Principles
A document, formally known as the Principles for the Delegation and Administration of ccTLDs. This document was developed by the ICANN Governmental Advisory Committee and documents a set of principles agreed by governments on how ccTLDs should be delegated and run.

General Availability Phase
Domains are awarded on first come first serve basis, granted that the domains are available after the previous phases have concluded.

Generic top-level domains (gTLDs)
A class of top-level domains that are used for general purposes, where ICANN has a strong role in coordination (as opposed to country-code top-level domains, which are managed locally).

Glue Record
An explicit notation of the IP address of a name server, placed in a zone outside of the zone that would ordinarily contain that information. All name servers are in-bailiwick of the Root Zone, therefore glue records is required for all name servers listed there. Also referred to as just "glue".

Hints File
A file stored in DNS software (i.e. recursive name servers) that tells it where the DNS root servers are located.

The name of a computer. Typically the left-most part of a fully-qualified domain name.

HyperText Transfer Protocol serves as the cornerstone protocol for World Wide Web, which allows the transfer of data between clients and servers.

See Internet Assigned Numbers Authority.

IANA Considerations
A component of RFCs that refer to any work required by IANA to maintain registries for a specific protocol.

IANA Contract
The contract between ICANN and the US Government that governs how various IANA functions are performed.

IANA Staff
See Internet Assigned Numbers Authority.

Internet Corporation for Assigned Names and Numbers(ICANN) is responsible responsible for the coordination of maintenance and methodology of several databases of unique identifiers related to the namespaces of the Internet, and ensuring the network's stable and secure operation.

Internal transfer
Internal transfer refers to a transfer of a domain name within the same registrar. This procedure may be simpler, than starting a domain transfer, which involves 2 different registrars. The internal transfer is possible, after two parties involved in the internal transfer come to an agreement about the terms of the transfer.

Internationalized domain name (IDN)
Internet domain name, which allows the use of a language-specific script or alphabet, such as Arabic, Cyrillic, and Chinese. Adoption of IDN domain names is a significant step towards including non-English speakers into the world of Internet. Internationalized domain name is stored in Domain Name System as ASCII strings, which are transcribed by the use of Punycode.

Internet Architecture Board (IAB)
The oversight body of the IETF, responsible for overall strategic direction of Internet standardization efforts. The IAB works with ICANN on how the IANA protocol parameter registries should be managed. The IAB is an activity of the Internet Society, a non-profit organization.

Internet Assigned Numbers Authority (IANA)
A department of ICANN tasked with providing various Internet coordination functions, primarily those described in a contract between ICANN and the US Government. The functions relate to ensuring globally-unique protocol parameter assignment, including management of the root of the Domain Name System and IP Address Space. ICANN staff within this department is often referred to as "IANA Staff".

Internet Coordination Policy (ICP)
A series of documents created by ICANN between 1999 and 2000 describing management procedures.

Internet Engineering Steering Group (IESG)
The committee of area experts of the IETF’s areas of work, that acts as its board of management.

Internet Engineering Task Force (IETF)
The key Internet standardization forum. The standards developed within the IETF are published as RFCs.

Internet Protocol (IP)
The fundamental protocol that is used to transmit information over the Internet. Data transmitted over the Internet is transmitted using the Internet Protocol, usually in conjunction with a more specialized protocol. Computers are uniquely identified on the Internet using an IP Address.

IP address
A unique identifier for a device on the Internet. The identifier is used to accurately route Internet traffic to that device. IP addresses must be unique on the global Internet.

Internet Protocol version 4. Refers to the version of Internet protocol that supports 32-bit IP addresses.

Internet Protocol version 6. Refers to the version of Internet protocol that supports 128-bit IP addresses.

Landrush Phase
This phase allows you a greater chance to obtain a domain name prior to General Availability, typically for an increased fee. The fee generally varies depending on how early you want to register. Priority is either first-come, first-served or will go to an auction cpr144449003101 if there are multiple applicants, depending on registry rules. A common fee structure that will be in use is the Early Access Program (EAP). Further details on a specific extensions landrush phase can be found under the landrush section for that a particular domain.

Mail exchange (mx) record
MX record determines which server the mail client will be retrieving the mail from. The MX records for individual domains can be set up in the DNS records section of the client's control panel.

New Generic Top Level Domain (New gTLD)
Starting on July 15th, 2013 ICANN has started process of delegating new Generic Top Level Domains, opening up new opportunities for the internet community. New extensions include popular categories like professional domains, IDNs, general interest domains, and brand domain names.

NS record
a type of record in a DNS zone that signifies part of that zone is delegated to a different set of authoritative name servers.

Parent domain
The domain above a domain in the DNS hierarchy. For all top-level domains, the Root Zone is the parent domain. The Root Zone has no parent domain as it is as the top of the hierarchy. Opposite of sub-domain.

Many of the registrars offer a free service of domain parking. This allows the customer to quickly register a domain name, and choose the hosting solution at a later date. Very often the registrar's parking DNS servers allow DNS record modification.

Paid pre-registration allows you to purchase the domain in the General Availability phase, and the domain will be submitted as soon as the General Availability phase opens.

Primary name server
Practically every domain extension requires minimum 2 DNS servers in order for the domain to be successfully registered. Primary name server is responsible for storing information about the domain routing and making it available for requests.

PTR record
The representation of a IP address to domain name mapping in the DNS system.

Recursive Name Server
A domain name server configured to perform DNS lookups on behalf of other computers.

The transfer of a delegation from one entity to another. Most commonly used to refer to the redelegation process used for top-level domains.

Redelegation process
A special type of root zone change where there is a significant change involving the transfer of operations of a top-level domain to a new entity.

Redemption Grace Period
Redemption Grace Period(RGP) is a period after the expiration date, in which the domain still belongs to the same client, however the functionality is put on hold. The domain can usually be restored after paying for RGP fee. gTLDs often have a Renewal Period of 30 days before the Redemption Grace Period starts.

Regional Internet Registry (RIR)
A registry responsible for allocation of IP address resources within a particular region.

See Registrant Contact

Registrant Contact
Majority of the registries require 4 contacts for a successful domain registration: Registrant, Administrative, Technical and Billing. The Registrant contact is the owner of the domain, and is the entity that holds right to use the particular domain name.

Registrar for .ca
An entity that can act on requests from a registrant in making changes in a registry. Usually the registrar is the same entity that operates a registry, although for domain names this role is often split to allow for competition between multiple registrars who offer different levels of support.

Registry Canada .ca
The authoritative record of registrations for a particular set of data. Most often used to refer to domain name registry, but all protocol parameters that IANA maintains are also registries.

Registry Operator for .ca Canada
The entity that runs a registry.

Reverse IP
A method of translating an IP address into a domain name, so-called as it is the opposite of a typical lookup that converts a domain name to an IP address.

A series of Internet engineering documents describing Internet standards, as well as discussion papers, informational memorandums and best practices. Internet standards that are published in an RFC originate from the IETF. The RFC series is published by the RFC Editor.

The highest level of the domain system.

Root Servers
The authoritative name servers for the Root Zone.

Root Zone
The top of the domain name system hierarchy. The root zone contains all of the delegations for top-level domains, as well as the list of root servers, and is managed by IANA.

Root Zone Management (RZM)
The management of the DNS Root Zone by IANA.

RZM Automation
A project to automate many aspects of the Root Zone Management function within IANA. Based on a software tool originally called "eIANA".

Secondary name server
Practically every domain extension requires minimum 2 DNS servers in order for the domain to be successfully registered. Secondary server is responsible for copying information from the primary server. The original purpose of secondary server is to take over the requests, if the primary server is down. Some of the registries no longer put an emphasis on which server is primary or secondary, but many international registries still use the old standard.

Sponsoring organization
The entity acting as the trustee of a top-level domain on behalf of its designated community.

Secure Sockets Layer (SSL) is a cryptographivc protocol, which is designed to provide communication security over internet. The data entered on the websites, using SSL, is encrypted, thus making it less susceptible to data theft.

In the domain hierarchy, or structure, subdomain is a domain, which is a part of a larger domain. For example, "www.icann.org" is a sub-domain of "icann.org", and "icann.org" is a sub-domain of "org". Subdomains can generally be setup through a DNS server management utility as A records or CNAME records.

Sunrise Phase
A phase in which holders of eligible trademarks have the opportunity to apply and register domain names that correspond to their trademarks. To participate in Sunrise for new gTLDs, trademark holders must validate their trademarks with the Trademark Clearinghouse (TMCH) first and must provide a valid Signed Mark Data (SMD) file for submission.

Technical Contact
Majority of the registries require 4 contacts for a successful domain registration: Registrant, Administrative, Technical and Billing. The Technical contact is intended to assist the Registrant(owner) contact in any queries that pertain to the technical aspects of managing the domain name.

Trademark Clearinghouse (TMCH)
The central database of verified trademarks that was created by ICANN to provide brand protection to trademark holders during ICANN’s new gTLD program. Its' a centralized database of verified trademarks, that is connected to each and every new Top Level Domain (TLD) that will launch.

Top-level domain (TLD)
The highest level of subdivisions with the domain name system. These domains, such as ".ca" and ".uk" are delegated from the DNS Root zone. They are generally divided into two distinct categories, generic top-level domains and country-code top-level domains.

Most commonly, the term transfer refers to a inter-registrar transfer of registrations. The procedure of the tranfer will largely depend on the TLD, and is most commonly completed by requesting an authorization code from the current registrar and initiating the transfer at another registrar.

Trust anchor
A known good cryptographic certificate that can be used to validate a chain of trust. Trust anchor repository (TAR) Any repository of public keys that can be used as trust anchors for validating chains of trust. See Interim Trust Anchor Repository (ITAR) for one such repository for top-level domain operators using DNSSEC.

An entity entrusted with the operations of an Internet resource for the benefit of the wider community. In IANA circles, usually in reference to the sponsoring organization of a top-level domain.

The Unicode representation of an internationalized domain name, i.e. how it is shown to the end-user. Contrast with A-label.

A standard describing a repertoire of characters used to represent most of the worlds languages in written form. Unicode is the basis for internationalized domain names.

Uniform resource locator (URL)
Uniform Resource Locator(URL), commonly known as web address, is an address to a resource on the internet. The URL consists of two components: Protocol Identifier(i.e. http, https) and the Resource name(i.e. icann.org)

Unsponsored top-level domain
A sub-classification of generic top-level domain, where there is no formal community of interest. Unsponsored top-level domains(.COM, .NET, .ORG, etc.) are administered according to the policies and processes established by ICANN.

URL Forwarding
URL Forwarding or URL redirection refers to the most common type of forwarding offered by domain registrars. Forwarding occurs when all pages from one domain are redirected to another domain.

A standard used for transmitting Unicode characters.

In the context of internationalized domain names, an alternative domain name that can be registered, or mean the same thing, because some of its characters can be registered in multiple different ways due to the way the language works. Depending on registry policy, variants may be registered together in one block called a variant bundle. For example, "internationalise" and "internationalize" may be considered variants in English.

Variant bundle
A collection of multiple domain names that are grouped together because some of the characters are considered variants of the others.

Variant table
A type of IDN table that describes the variants for a particular language or script. For example, a variant table may map Simplified Chinese characters to Traditional Chinese characters for the purpose of constructing a variant bundle.

Web host (Hosting Provider)
Web host is a type of an Internet service, which allows users to host content and/or email services by providing hosting space. Most often the hosting providers include control panels and tools for building a website and maintaining mail records.

A simple plain text-based protocol for looking up registration data within a registry. Typically used for domain name registries and IP address registries to find out who has registered a particular resource. (Usage note: not "Whois" or "whois")

WHOIS database
Used to refer to parts of a registry’s database that are made public using the WHOIS protocol, or via similar mechanisms using other protocols (such as web pages, or IRIS). Most commonly used to refer to a domain name registry’s public database.

WHOIS gateway
An interface, usually a web-based form, that will perform a look-up to a WHOIS server. This allows one to find WHOIS information without needing a specialized computer program that speaks the WHOIS protocol.

WHOIS server
A system running on port number 43 that accepts queries using the WHOIS protocol.

Wire format
The format of data when it is transmitted over the Internet (i.e. "over the wire"). For example, an A-label is the wire format of an internationalized domain name; and UTF-8 is a possible wire format of Unicode.

A machine-readable file format for storing structured data. Used to represent web pages (in a subset called HTML) etc. Used by IANA for storing protocol parameter registries.

Zone (DNS Records)
The zone file, also know as the DNS records is a vital component of DNS system, which contains various DNS records, which point to the location of content and email servers for each individual domain. Editing zone is made possible in the client's control panel.

Signed Mark Data (SMD)
A Signed Mark Data (SMD) is file that will allow you to register domain names during the sunrise period of new gTLD’s and request other services. It validates that you trademark has been verified within the Trademark Clearinghouse (TMCH).

Trademark Claims
The trademark claims period extends for 90 days after the close of the Sunrise period. During the Claims period, anyone attempting to register a domain name matching a trademark that is recorded in the Trademark Clearinghouse will receive a notification displaying the relevant mark information. If the notified party goes and ahead and registers the domain name the Trademark Clearinghouse will send a notice to those trademark holders with matching records in the Clearinghouse, informing them that someone has registered the domain name.
