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.

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with the
   provisions of BCP 78 and BCP 79.

1.  Introduction

   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

   Portions of three IANA registries are associated with the Internet
   Numbers Registry System: AS Numbers, IPv4 Addresses, and IPv6
   Addresses.

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).

   Reservations of special-purpose AS Numbers are made through Internet
   Standards actions.

Internet Numbers Registries                                December 2013

   At this time, the special-purpose AS numbers are:

   AS Numbers             Reason for Reservation
   ---------------------  -------------------------------------------
   0                      Reserved by [draft-ietf-idr-as0]
   23456                  AS_TRANS; reserved by [RFC6793]
   64496-64511            For documentation and sample code; reserved
                            by [RFC5398]
   64512-65534            For private use; reserved by [RFC6996]
   65535                  Reserved by [RFC1930]
   65536-65551            For documentation and sample code; reserved
                            by [RFC5398]
   4200000000-4294967294  For private use; reserved by [RFC6996]
   4294967295             Reserved

2.2.  IPv4 Addresses

   The allocation and registration functions for all non-reserved
   globally unique unicast IPv4 unicast addresses are handled by the
   Internet Numbers Registry System in accordance with policies
   developed by the Regional Internet Registries (RIRs).

   Reservation of special-purpose IPv4 addresses are made through
   Internet Standards actions.  Reserved IPv4 unicast addresses are
   registered in the Special Purpose IP address registries [RFC6890].

   At this time, the special-purpose IPv4 unicast addresses are:
