Internet Assigned Numbers Authority

The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. Learn more about what we do »

Domain Names

IANA manages the DNS Root Zone (assignments of ccTLDs and gTLDs), as well as the .int registry, and the .arpa zone.

Number Resources

IANA coordinates the global IP and AS number space, and allocates these to Regional Internet Registries.

Protocol Assignments

IANA is the central repository for protocol name and number registries, used in many Internet protocols.

 
2010-07-15 — The DNS Root Zone is now signed with DNSSEC, with trust anchors and other information now available.
