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

   Portions of three

   Three IANA registries are associated with the Internet Numbers
   Registry System: AS Numbers, unicast IPv4 Addresses, and unicast IPv6
   Addresses.  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).

   Reservations (RIRs) public policy development processes.

   Some special-purpose AS numbers have been reserved.  Section 3 of
   this document establishes an IANA registry for special-purpose AS
   Numbers are that have already been reserved.  Future additions to this
   registry can be made through Internet
   Standards actions.

Internet Numbers Registries                                December 2013

   At this time, "IETF Review" as defined in [RFC5226].
   Once a future reservation is approved, it is recorded in the special-purpose special-
   purpose AS numbers are:

   AS 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 unicast addresses are handled by the Internet
   Numbers Registry System in accordance with policies developed by the
   Regional Internet Registries (RIRs).

   Reservation (RIRs) public policy development
   processes.

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

   At
   IANA registry [IANA-IPv4-Reg].  Future additions to this time, registry can
   be made through "IETF Review" as defined in [RFC5226].  Once a future
   reservation is approved, it is recorded in the special-purpose IPv4 unicast addresses are:

   IPv4 Addresses   Reason for Reservation
   ---------------  -----------------------------------------------
   0/8              For self-identification; reserved by [RFC1122]
   10/8             For private use; reserved by [RFC1918]
   100.64/10        For shared
   address space; reserved by [RFC6598]
   127/8            For loopback; reserved by [RFC1122]

                      by [RFC5737]
   240/4            Reserved by [RFC1112]

Internet Numbers Registries                                December 2013 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, IETF [RFC3513], with the
   expectation that further assignment of globally unique unicast
   address space will be made from this reserved space in accordance
   with future needs.

   The allocation and registration functions for all non-reserved
   globally unique unicast IPv6 unicast addresses are handled by the Internet
   Numbers Registry System in accordance with policies developed by the
   Regional Internet Registries (RIRs).

   Reservation (RIRs) public policy development
   processes.

   Reservations of special-purpose IPv6 addresses are can be found in the
   IANA registry [IANA-IPv6-Reg].  Future additions to this registry can
   be made through
   Internet Standards actions.  Reserved IPv6 unicast addresses are
   registered "IETF Review" as defined in [RFC5226].  Once a future
   reservation is approved, it is recorded in the Special Purpose IP special-purpose IPv6
   address Registries [RFC6890]. registry with a reference to the IESG-approved RFC that
   documents the reservation.

3.  IANA Considerations

   Please establish an IANA registry for special-purpose AS numbers.
   Future additions to this registry can be made through "IETF Review"
   as defined in [RFC5226].  At this time, the special-purpose IPv6 addresses AS
   numbers are:

                     mapped, link-local, site-local, and addresses

   2002::/16 [RFC5398]
   4200000000-4294967294  For 6to4; private use; reserved by [RFC3056]

3.  IANA Considerations

   "IETF Review" as defined in [RFC5226] is required to reserve special-
   purpose AS numbers, IPv4 addresses, or IPv6 addresses. [RFC6996]
   4294967295             Reserved AS
   numbers, IPv4 addresses, or IPv6 addresses may be designated to
   support testing, IETF experimental activities, or other special uses
   (e.g., anycast).  These reservations are recorded in the relevant
   IANA registry with a Special Purpose designation, referencing the
   IESG-approved RFC that documents the reservation.

4.  Security Considerations

   This document identifies the IANA registries that are part of the
   Internet Numbers Registry System at this time.  It does not change
   the security posture of the Internet in any way.

   Network operators should take care that special-purpose numbers and
   addresses are used on the public Internet Numbers Registries                                December 2013 in a manner that is
   consistent with their reserved purpose.
