content guidelines. In particular, ensure a neutral point of view and proper sourcing of information.
A Country Code Top-Level Domain (ccTLD) is a two-letter Internet top-level domains (TLDs) specifically designated for a particular country, sovereign state or autonomous territory for use to service their community. ccTLDs are derived from ISO 3166-1 alpha-2 country codes.[1]
The implementation of ccTLDs was started by IANA, which is not a physical organization or an individual but it is part of ICANN.[2] The delegation and creation of ccTLDs is presented within RFC 1591. In order to determine whether new ccTLDs should be added or not, the IANA follows the provisions of ISO 3166 - Maintenance Agency. Briefly, "our policy is to create new country-code top-level domains when the country or territory is listed on the ISO 3166-1 standard."
More information related to the development of new ccTLDs can be found in IANA's Procedures for Establishing ccTLDs. [3]
Within its database, IANA maintains authoritative information related to ccTLDs. This includes sponsoring organizations, technical and administrative contacts, name servers, registration URLs and other such information. This type of information provides extra details regarding the IANA's procedures for maintaining the ccTLD database.
Delegation and Redelegation[edit | edit source]
The process through which the designated manager, or managers, is changed is known as redelegation. The redelegation process follows the provisions of ICP-1 and RFC 1591. IANA receives all requests of a sponsoring organization related to delegation and redelegation for the ccTLDs. The requests are then analyzed by IANA based on various technical and public criterion. The request, accompanied by the IANA analysis, is finally sent to the ICANN Board of Directors for approval or refusal. If approved, IANA is also responsible for the implementation of the request.[4]
Conceptually speaking, the delegation and redelegation processes are simple. However, they can easily become complex if there are many organizations and individuals involved in the process. There is a set of steps that must be followed before sending the request for delegation or redelegation. An initial request should be developed, based on The Change Request Template and supplementary information, to prove that the eligibility criteria have been met by the initial request. All the information supplied is used by IANA to analyze the request received.[4]

Related Article - Open Use ccTLD
An open ccTLD refers to a country code top level domain name that can be registered by anyone, regardless of which country the person resides in. These ccTLDs generally represent a particular branding opportunity aside from the name of the country or territory it represents. Examples include .cc (Cocos Island) for consulting companies, .tv (Tuvalu) for television, .ws (Western Samoa) for websites, and .co (Colombia) as an alternative to .com for companies.[9]
The following is a list of the current ccTLDs, including their registry operators and any special notes about registration of the domains.[10][11]
