Protocol Registries
Protocol parameter registries represent the authoritative record of many of the codes and numbers contained in a variety of Internet protocols. We maintain these records in compliance with the associated technical standards and allocation policies, and we provide this service in coordination with the Internet Engineering Task Force (IETF).
To view or download individual protocol registries, navigate to the individual registries through the index below. Registry data is available for bulk retrieval via Rsync (recommended) or FTP.
To obtain a registration in an existing registry, or to modify existing registrations, consult the relevant application form. For information on creating new registries, please see RFC 8126 for guidance.
