<DIV><FONT face=Arial size=2>Very good question.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The thinking around here goes like this (with all
the usual "my thoughts, not my employer disclaimer"):</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Pre-V4 Exhaustion: Dual stack 4/4 and 6/6
(and maybe 4/6)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>As we approach exhaustion: Dual Stack 4/4/4 and
6/6 (and maybe 4/6)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>That middle '4' is a bone of great contention which
I am not going to let go of. Failed to get it APNIC 25.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Getting into more general terms I think we all need
to acknowledge that for 99.99% of our customers, there is nothing in V6 for
them. For the industry, it's all about keeping the lights on in world depleted
of V4 address space.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My personal view is that, from a customer's
perspective, we should not be insisting that they upgrade their home network
devices (PC's) to support V6. That implies some clever CPE and thats the real
problem. The CPE vendors are behind.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [AusNOG] What does an IPv6
broadband service look like? WAS Re:IPv4 Exhaustion</DIV>
<DIV><BR></DIV>To change direction a little here to focus this on something
other than NAT:
<DIV><BR></DIV>
<DIV>One thing that is on my mind and we have internally been struggling with
is:</DIV>
<DIV><BR></DIV>
<DIV>What DOES an IPv6 broadband service really look and smell like?</DIV>
<DIV><BR></DIV>
<DIV>It's not that easy to map our existing ingrained views on an IPv4
broadband service onto a v6 or dual stack world.</DIV>
<DIV><BR></DIV>
<DIV>What IP ranges do customers get with IPv6? /128 and NAT/Proxy?
/96? /64? /48? etc </DIV>
<DIV>Do they necessarily get a static subnet? Why/Why Not? What
implications does it have for your internal IGP?</DIV>
<DIV>If they get a static subnet then do they get to play with reverse
mappings?</DIV>
<DIV>How will the transition from v4 to dual stack to some interim step to v6
only go?</DIV>
<DIV><BR></DIV>
<DIV>I know a lot of the geeks will go "well, obviously a static /48 with our
own controllable reverse mappings" but on a LARGE scale with mostly non-geek
home users then what exactly does it look like?</DIV>
<DIV><BR></DIV>
<DIV>What do the CPE vendors need to support? What do we need to
support? </DIV>
