Network Working Group G. Huston Request for Comments: 4147 APNIC Category: Informational August 2005 Proposed Changes to the Format of the IANA IPv6 Registry 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 Internet Society (2005). Abstract This document proposes a revised format for the IANA IPv6 address registries. Rather than providing a formal definition of the format, it is described by giving examples of the (current as of preparation of this document) contents of the registries in the proposed format. The proposed format would bring the IANA IPv6 address registries into alignment with the current IPv6 Address Architecture specification, as well as update it to a more useful and generally accepted format. 1. Introduction This document proposes a revised format for the IANA IPv6 address registries. The proposed format would bring the IANA IPv6 address registries into alignment with the current IPv6 Address Architecture specification, as well as update it to a more useful and generally accepted format. The current (as of preparation of this document) IANA IPv6 registries [iana-ipv6-registry] [iana-ipv6-tla] are based on a now-deprecated address architecture that used the concept of Top Level Aggregation Identifiers (TLAs) and sub-TLAs. The current IPv6 Address Architecture [RFC3513] uses the terminology of Global Identifiers instead of TLAs and sub-TLAs. Huston Informational [Page 1] RFC 4147 IANA IPv6 Registry August 2005 2. IPv6 Address Registry The proposed format for the IPv6 address registry is indicated by example, using the registry state that is current as of preparation of this document, in Figure 1. The registry explicitly notes which entity is placing a reservation on an address block and notes the defining RFC document for each allocation. The proposed format of the registry is a title line, the date of the last change to the registry, the registry in a tabular format, notes and references. The table uses 4 columns. Within the table, the first column contains an IPv6 address prefix, using a hexadecimal notation of the address prefix and a prefix length. There are no overlapping address blocks in the first column, and the set of address blocks in the registry spans the entire IPv6 address space. The second column denotes the current disposition of the address block, using notation derived from the defining RFC document. The third column contains a reference to the RFC that describes the current disposition of the address block. The fourth column uses numeric footnote notation to reference any additional text associated with the address block. The notes in the registry may include a summary of previous disposition status values associated with an address block, as this summary is specifically not included in the registry table. The notes are numbered sequentially. The reference section uses a conventional citation format. The references include documents referenced in the registry table and documents referenced in the notes. ----------------------------------------------------- INTERNET PROTOCOL VERSION 6 ADDRESS SPACE [last updated 13 January 2005] IPv6 Prefix Allocation Reference Note ----------- ---------- --------- ---- 0000::/8 Reserved by IETF RFC3513 [1] 0100::/8 Reserved by IETF RFC3513 0200::/7 Reserved by IETF RFC4048 [2] 0400::/6 Reserved by IETF RFC3513 0800::/5 Reserved by IETF RFC3513 1000::/4 Reserved by IETF RFC3513 2000::/3 Global Unicast RFC3513 [3] 4000::/3 Reserved by IETF RFC3513 Huston Informational [Page 2] RFC 4147 IANA IPv6 Registry August 2005 6000::/3 Reserved by IETF RFC3513 8000::/3 Reserved by IETF RFC3513 A000::/3 Reserved by IETF RFC3513 C000::/3 Reserved by IETF RFC3513 E000::/4 Reserved by IETF RFC3513 F000::/5 Reserved by IETF RFC3513 F800::/6 Reserved by IETF RFC3513 FA00::/7 Reserved by IETF RFC3513 FC00::/7 Reserved by IETF RFC3513Show full document text
