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.

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.

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 addr...
