Country code top-level domainsA country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country or a dependent territory.
ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs. Creation and delegation of ccTLDs is performed by the Internet Assigned Numbers Authority (IANA), and with certain exceptions noted below corresponds to the ISO 3166-1 alpha-2 country codes maintained by the United Nations.
The IANA (currently contracted to ICANN) is responsible for determining an appropriate trustee for each ccTLD. Administration and control is then delegated to that entity, which is responsible for the policies and operation of the domain; the current delegation can be determined from IANA's list of ccTLDs. Individual ccTLDs may thus have varying requirements and fees for registering subdomains. There may be a local presence requirement (for instance, citizenship or other connection to the ccTLD), as for example the Canadian (ca) and German (de) domains, or registration may be open.
