The IESG has received a request from the IPv6 Operations WG (v6ops) to
consider the following document:
- 'Unique IPv6 Prefix Per Host'
  <draft-ietf-v6ops-unique-ipv6-prefix-per-host-03.txt> as Best Current
Practice

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
[email-masked] mailing lists by 2017-06-06. Exceptionally, comments may be
sent to [email-masked] instead. In either case, please retain the

Abstract

   In some IPv6 environments, the need has arisen for hosts to be able
   to utilize a unique IPv6 prefix, even though the link or media may be
   shared.  Typically hosts (subscribers) on a shared network, either
   wired or wireless, such as Ethernet, WiFi, etc., will acquire unique
   IPv6 addresses from a common IPv6 prefix that is allocated or
   assigned for use on a specific link.

   In most deployments today, IPv6 address assignment from a single IPv6
   prefix on a shared network is done by either using IPv6 stateless
   address auto-configuration (SLAAC) and/or stateful DHCPv6.  While
   this is still viable and operates as designed, there are some large
   scale environments where this concept introduces significant
   performance challenges and implications, specifically related to IPv6
   router and neighbor discovery.

   This document outlines an approach utilising existing IPv6 protocols
   to allow hosts to be assigned a unique IPv6 prefix (instead of a
   unique IPv6 address from a shared IPv6 prefix).  Benefits of unique
   IPv6 prefix over a unique IPv6 address from the service provider
   include improved subscriber isolation and enhanced subscriber
   management.
