.gyeongbuk.kr 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.
The representation of an IPv4 address in the DNS system.
The representation of an IPv6 address in the DNS system.
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 Korean .gyeongbuk.kr 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.
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.
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.
The combination of a recursive name server and a caching name server.
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.
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.
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.
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.
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 "188.8.131.52", 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.

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 “.gyeongbuk.kr”.
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)

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.

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

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

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.
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.
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.
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 ".gyeongbuk.kr" 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.
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.

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

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