IANA internet country code TLD - Country Codes
Although you may already be familiar with internet top-level domains such as “.com” and “.net”, IANA internet country code top-level domains (ccTLDs) are internet top-level domains that are generally used or reserved for a country or other territory. These codes are implemented by the Internet Assigned Numbers Authority (IANA). IANA is also responsible for determining an appropriate trustee for each ccTLD.
A number of the world’s smallest countries have licensed their TLDs for worldwide commercial use. Many of these countries have ccTLDs that are considered “vanity” ccTLDs. Vanity ccTLDs are TLDs which are used for various purposes outside their home countries because their code either means something or is a word in English, or another language. Some examples are Tuvalu (.tv), Italy (.it), and Tonga (.to).
