Internet Engineering Task Force (IETF) R. Housley Request for Comments: 7249 Vigil Security Category: Informational May 2014 ISSN: 2070-1721 Internet Numbers Registries Abstract RFC 7020 provides information about the Internet Numbers Registry System and how it is used in the distribution of autonomous system (AS) numbers and globally unique unicast Internet Protocol (IP) address space. This companion document identifies the IANA registries that are part of the Internet Numbers Registry System at this time.

Housley Informational [Page 1] RFC 7249 Internet Numbers Registries May 2014 1. Introduction In accordance with the IETF-IANA Memorandum of Understanding [RFC2860], RFC 7020 [RFC7020] provides information about the Internet Numbers Registry System and how it is used in the distribution of autonomous system (AS) numbers and globally unique unicast Internet Protocol (IP) address space. This companion document identifies the IANA registries that are part of the Internet Numbers Registry System at this time. 2. Internet Numbers Registries Three IANA registries are associated with the Internet Numbers Registry System: "Autonomous System (AS) Numbers", "IANA IPv4 Address Space Registry", and "IPv6 Global Unicast Address Assignments". However, in each case, there are special-purpose values, and those special-purpose values are outside the Internet Numbers Registry System. 2.1. Autonomous System Numbers For historical reasons, there are 16-bit AS numbers and 32-bit AS numbers. However, the 16-bit AS numbers are really just zero through 65535 of the 32-bit AS number space. The allocation and registration functions for all non-reserved AS numbers are handled by the Internet Numbers Registry System in accordance with policies developed by the Regional Internet Registries (RIRs) in accordance with their processes. Some special-purpose AS numbers have been reserved. Section 3 of this document establishes an IANA registry for special-purpose AS Numbers that have already been reserved. Future additions to this registry can be made through "IETF Review" as defined in [RFC5226]. Once a reservation is approved, it is recorded in the special-purpose AS numbers registry with a reference to the IESG-approved RFC that documents the reservation. Housley Informational [Page 2] RFC 7249 Internet Numbers Registries May 2014 2.2. IPv4 Addresses The allocation and registration functions for all non-reserved, globally unique unicast IPv4 addresses are handled by the Internet Numbers Registry System in accordance with policies developed by the RIRs in accordance with their processes. Reservations of special-purpose IPv4 addresses can be found in the IANA registry [IANA-IPv4-Reg]. Future additions to this registry can be made through "IETF Review" as defined in [RFC5226]. Once a reservation is approved, it is recorded in the special-purpose IPv4 address registry with a reference to the IESG-approved RFC that documents the reservation. 2.3. IPv6 Addresses The vast bulk of the IPv6 address space (approximately 7/8ths of the whole address space) is reserved by the IETF [RFC4291], with the expectation that further assignment of globally unique unicastShow full document text
