                      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.

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.

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
