hello,
  this could really benefit from CASM architecture, IMHO.

Marc.

>    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.
