1.  Introduction

   This is a direction to [IANA] concerning the creation and management
   of the IANA IPv4 Special Purpose Address Registry.  The registry will
   be used for recording IETF protocol assignments from 192.0.0.0/24 and
   any other address prefixes allocated to the registry in the future,
   as described in Section 3.

2.  IANA IPv4 Special Purpose Address Block

   [RFC5735] records the assignment of an IPv4 address prefix to IANA
   for IETF protocol assignments.

      192.0.0.0/24 - This block is reserved for IETF protocol
      assignments.

   This address allocation to IANA is intended to support IETF protocol
   assignments.  A more general view of the roles of IANA with respect
   to address allocation functions is documented in [RFC2860]:

      4.3. [...]  Note that [...] (b) assignments of specialised address
      blocks (such as multicast or anycast blocks), and (c) experimental
      assignments are not considered to be policy issues, and shall
      remain subject to the provisions of this Section 4.  (For purposes
      of this MOU, the term "assignments" includes allocations.)

   The reference to Section 4 here is to the general technical work for
   the IANA as described in [RFC2860]:

      4.1.  The IANA will assign and register Internet protocol
      parameters only as directed by the criteria and procedures
      specified in RFCs, including Proposed, Draft, and full Internet
      Standards and Best Current Practice documents, and any other RFC
      that calls for IANA assignment.

   This document directs IANA to designate special purpose address
   blocks in compliance with [RFC2860].

RFC 5736                 IPv4 Special Registry              January 2010

   This document directs IANA to open an IPv4 Special Purpose Address
   Registry for the management of these IANA-designated address blocks.
   Special Purpose registrations to be made from this registry include
   addresses for IETF protocol assignments and other special purpose
   cases, as documented in IESG-reviewed RFCs, according to the
