sTLD

.int domain information

The .int TLD is reserved for international organizations and treaty groups, used by entities like the UN and the EU. However, many international organizations prefer to use .org, a gTLD for non-profits, or their country's ccTLD (like .cn or .ca), rather than .int.

Introduction

The .int TLD stands for "international" and is a sponsored top-level domain (sTLD) in the internet domain name system, primarily intended for international intergovernmental organizations and treaty-based entities.

Initially, the .int domain was created for the North Atlantic Treaty Organization (NATO) to replace the old .nato domain.

Historically, the .int domain was also used for the Internet infrastructure database. There were plans to move .arpa to .int, but in 2000, the Internet Architecture Board (IAB) recommended reinstating .arpa for its original purpose, and the internet infrastructure database was no longer associated with .int.

According to the Internet Assigned Numbers Authority (IANA) policies based on RFC 1591, the sTLD .int is reserved for organizations established by international treaties, UN agencies, and entities or bodies with observer status at the UN. The .int domain is considered to have the strictest registration requirements among all TLDs because the registrant must be a subject of international law. The application process requires the applicant to provide evidence of a treaty basis, including a United Nations treaty registration number, and to have an independent legal personality.
