.com.do Glossary of Technical Terms

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

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

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.

A subcategory of private IP address. See Private IP Addresses.

A subset of IRIS for performing registration lookups on IP addresses.

.ARPA 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 Internationalised Domain Names for Applications.

Authoritative Name Server
a domain name server configured to host the official record of the contents of a DNS zone. Each Dominican Republic ..com.dodomain 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.

Autonomous System Number (AS number, ASN)
A number used by Internet routing protocols to uniquely identify the routing policy of a particular network operator.

Autonomous System Number (AS number, ASN)
A number used by Internet routing protocols to uniquely identify the routing policy of a particular network operator. They can be considered to be similar to a ‘postcode’ used for physical mail. They are allocated to network operators via regional Internet registries.

Country-code top-level domain (ccTLD)
A class of top-level domains only assignable to represent countries listed in the ISO 3166-1 standard. At present these are two-letter codes like .com.do etc., however in the future it is expected there will be non-Latin equivalents also available. Much of the policy-making for individual country-code top-level domains is vested with a local sponsoring organisation, as opposed to other top-level domains where ICANN sets the policy. It is a requirement that ccTLDs are operated within the country they are designated so appropriate local laws, governments etc. have a say in how the domain is run

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.

A subset of IRIS for performing checks on whether a domain name is available to register. It is more lightweight, and has less privacy implications, than DREG as it does not transmit registration data other than simple availability.

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.

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.

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.do zone would refer to the portion of the DNS delegated that ends in .com.do.

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 internationalised domain names, the labels may be referred to as A-labels and U-labels.

Domain Name Registrar for .com.do
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 .com.do, Dominican Republic
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 system on the Internet that 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.

common way of referring to a specific top-level domain. For example "dot .com.do" refers to the "INFO" top-level domain. Written in text as ".com.do".

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.

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".

A standard used for transmitting Unicode characters.

In the context of internationalised 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.
