Network Working Group G. Huston Request for Comments: 4773 APNIC Category: Informational December 2006 Administration of the IANA Special Purpose IPv6 Address Block Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The IETF Trust (2006). Abstract This is a direction to IANA concerning the management of the IANA Special Purpose IPv6 address assignment registry. 1. Introduction This is a direction to IANA concerning the management of the IANA Special Purpose IPv6 address assignment registry. 2. IANA IPv6 Special Purpose Address Block [RFC2928] specified the assignment of the IPv6 address prefix to IANA. The rationale for this allocation is: "The block of Sub-TLA IDs assigned to the IANA (i.e., 2001: 0000::/29 - 2001:01F8::/29) is for assignment for testing and experimental usage to support activities such as the 6bone, and for new approaches like exchanges." [RFC2928] This address allocation to IANA was intended to support testing and experimental activities. 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.)" [RFC2860] Huston Informational [Page 1] RFC 4773 IANA IPv6 Registry December 2006 The reference to section 4 here is to the general technical work for the IANA: "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." [RFC2860] This document directs IANA to undertake designation of special purpose address blocks within the purview of direct assignments by the IANA under the terms of the assignment criteria specified in RFC 2928. This document directs IANA to open a Special Purpose IPv6 address registry for the management of these IANA-designated address blocks. Special Purpose registrations to be made from this registry include addresses for experimental purposes, as described in [RFC2928], and other special purpose cases, as documented in IESG-reviewed published RFCs, according to the provisions described in section 4.1 of [RFC2860]. 3. IANA Considerations IANA maintains an "IANA IPv6 Address Special Purpose Registry". The registry records current IANA address designations from the IANA- managed Special Purpose IPv6 address pool. This recommendation concerns the management of the address pool assigned by the IETF to the IANA in July 1999 by [RFC2928], namely 2001:0000::/23. Following the policies outlined in [RFC2434], further assignments of address space to IANA for subsequent designation of address prefixes for the purposes listed here shall be undertaken only through an IETF Consensus action. Such directions for assignments of address space to augment the IANA-managed special purpose address pool should, in the general course of events, be consistent with prevailing IANA IPv6 address management policies [IPv6-Policies]. IANA may undertake IPv6 address designations in support of special purposes as requested in "IANA Considerations" sections in IESG- reviewed RFCs, where an address is requested with an intended use of the designated address block for the purpose of testing or experimental usage activities initiated by IETF, or for specialised use of the address block in a context (e.g., anycast) associated with an Internet Standards track protocol. Huston Informational [Page 2] RFC 4773 IANA IPv6 Registry December 2006 The IANA IPv6 Special Purpose Address Registry records, for all current address designations undertaken by IANA: 1. The designated address prefix. 2. The RFC that called for the IANA address designation. 3. The date the designation was made. 4. The date the use designation is to be terminated (if specified as a limited-use designation). 5. The nature of the purpose of the designated address (e.g., unicast experiment or protocol service anycast). 6. For experimental unicast applications and otherwise asShow full document text
