Re: .int
Be careful with that: the International Telecommunication Union has a .int domain:
That would be because .int is reserved for international organisations.
Two relevant paragraphs from the Unreliable Source:
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.[1] 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 organizations, United Nations agencies, and organizations or entities having observer status at the UN.[2] 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.
