[v6ops] Fwd: I-D Action: draft-ietf-v6ops-unique-ipv6-prefix-per-host-07.txt

In the 2nd para of Sec. 4, it reads:

	“… a Unique IPv6 prefix (currently a /64 prefix)…”

Assuming that there’d be at some place upwards where a /48 prefix would be present, which prefix length is up to a common practice for ISPs in assigning a prefix to a site, does the above spec means:

	o the maximum number of devices that the proposed scenario can accommodate is 64K (2**16; 64 - 48 = 16)?

> 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.
