[ppml] [iesg-secretary at ietf.org: Last Call: 'Unique Local IPv6 Unicast Addresses' to Proposed Standard]

[Suzanne Woolf]

Per discussion in Vancouver....The IETF has an internet-draft
(proposed RFC) out for review regarding the assignment of a global
IPv6 prefix intended strictly for local communications. This is
approximately the role filled by RFC 1918 address space in the IPv4
address hierarchy, but also includes an attempt to resolve the
addressing conflicts that arise now when two entities using RFC 1918
space want to interoperate.

The IESG has solicited comments, preferring to receive them by July
15. 

The introduction states:

   This document defines an IPv6 unicast address format that is globally
   unique and is intended for local communications [IPV6].  These
   addresses are called Unique Local IPv6 Unicast Addresses and are
   abbreviated in this document as Local IPv6 addresses.  They are not
   expected to be routable on the global Internet.  They are routable
   inside of a more limited area such as a site.  They may also be
   routed between a limited set of sites.

   Local IPv6 unicast addresses have the following characteristics:

      - Globally unique prefix.
      - Well known prefix to allow for easy filtering at site
        boundaries.
      - Allows sites to be combined or privately interconnected without
        creating any address conflicts or requiring renumbering of
        interfaces using these prefixes.
      - Internet Service Provider independent and can be used for
        communications inside of a site without having any permanent or
        intermittent Internet connectivity.
      - If accidentally leaked outside of a site via routing or DNS,
        there is no conflict with any other addresses.
      - In practice, applications may treat these addresses like global
        scoped addresses.

Subject: Last Call: 'Unique Local IPv6 Unicast Addresses' to Proposed
	Standard 

The IESG has received a request from the IP Version 6 Working Group WG to 
consider the following document:

- 'Unique Local IPv6 Unicast Addresses '
   <draft-ietf-ipv6-unique-local-addr-05.txt> as a Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action.  Please send any comments to the
iesg at ietf.org or ietf at ietf.org mailing lists by 2004-07-15.
