Protocol Registries

IANA is responsible for maintaining many of the codes and numbers contained in a variety of Internet protocols, enumerated below. We provide this service in coordination with the Internet Engineering Task Force (IETF).

For more information on how to create registries, please see RFC 5226, Section 4. This document also covers the requirements for IANA Considerations in RFCs.

To view the various protocol registries, just click on their titles. To apply to modify a registry, use the relevant form. The qualifications for changing a protocol vary depending on the governing standards documents.
