The domain name int is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. Its name is derived from the word international, characterizing its use for international organizations and treaty-related purposes. The first use of this domain was by NATO, which had previously been assigned the top-level domain nato.
According to Internet Assigned Numbers Authority (IANA) policy, based on RFC 1591, the sTLD int is reserved for international treaty-based organisations, United Nations agencies, and organisations or entities having Observer status at the UN.
int is considered to have the strictest application policies of all TLDs, as it implies that the holder is a subject of international law. For this reason, the application procedure requires the applicant to provide evidence that it is indeed treaty-based by providing a United Nations treaty registration number and that it has independent legal status.
Hence, the Stockholm Convention on Persistent Organic Pollutants (POPS) saw its initial application for a domain name under int rejected on the grounds that the convention did not explicitly create an entity subject of international law. However, POPS appealed to the IANA Reconsideration Committee and obtained its domain (pops.int) on the grounds that other conventions lacking such specific language had nevertheless obtained a registration. The IANA granted the domain after the committee determined that (1) the organisation was chartered by a treaty that was very likely to enter into force, and (2) despite lacking a legal track record, it met "the requirement for independent international legal personality." This grant was subject to the proviso that the status of eligibility be renewed if the treaty hadn't entered into force within four years of the registration.
Additionally, the domain int was historically also used for Internet infrastructure databases. The name space arpa had been slated to be moved into int, but in 2000 the Internet Architecture Board recommended that no new infrastructure databases should be added to int and that arpa retain its function. The only remaining technical role of int was for reverse translation of IPv6 addresses in the zone ip6.int. This zone was officially removed on 6 June 2006 in favor of ip6.arpa, also administered by IANA.
As of June 2012, the domain int consists of 166 subdomain delegations.
The subdomain eu.int was used by the European Union-affiliated institutions. However, the aforementioned institutions' domain names switched to the TLD eu on May 9, 2006 (Europe Day). All previous eu.int addresses continued to be accessible for a transitional period of at least one year. As of 2012, the European Central Bank continues to use ecb.int in addition to ecb.eu, and the .int domain is the one used for email purposes.
Several domains under int were granted prior to the application of the strict guidelines. The Young Men's Christian Association (YMCA) is an example of the loose guidelines applied in the early 1990s. IANA has not withdrawn the existing assignment from YMCA (ymca.int) and other organisations such as The Phone Company (tpc.int) who do not meet the current criteria.
