.int

Definition
The .int TLD is strictly limited to organizations, offices, and programs which are endorsed by a treaty between two or more nations.

Overview
.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.
