Until there's a practical solution for multihoming, this whole discussion is
pretty pointless.

multihoming is simple, you get an address block and route it to your upstreams.
the policy surrounding that is another debate, possibly for another group
this thread is discussing how v4 to v6 migration can operate on a network level

Amazink! Some things on NANOG _never_ change. Trawling for trolls I must be.
If you want to emulate IPv4 and destroy the DFZ, yes, this is trivial. And you
should go ahead and plan that migration.
As you well known, one of the core assumptions of IPv6 is that the DFZ policy
stay intact,
In ARIN you have a policy to request IPv6 PI. So what is the problem ?

Hey, that's a very simplistic IGP point of view !!
I'm afraid I disagree :)

Hi Christian,
I am not seeing how v4 exhaustion, transition to v6, multihoming in v6 and
destruction ov DFZ are correlated.
If you took everything on v4 today and migrated it to v6 tomoro the routing
table would not grow - actually by my calculation it should shrink (every ASN
would only

Given IPv6 is IPv4 with 96 more bits (or, if you prefer 16 more bits
from the ISP perspective), why would you assume there is a choice?

I'm not sure what destroy the DFZ
Hi Steve,
Sure... I've never mention 3 STM4... the example said 3 carriers.
OK, you may do it with communities, but if you advertise all in just one
prefix, even with communities, I find it very difficult to control the
trafic when it pass through 2 or more AS (it may be quite easy for the

A. v4 runs out, use v6 or similar
B. not run out of v4
The detail of A and B may safely be debated by all for some time as
nobody knows what will happen, feel free

Hmm I find this topic quite interesting.
First is the belief that the Internet will suddenly break on the day when the
last IP block is allocated by an RIR - the fact that most of the v4 space is
currently not being announced may mean we have many years before there are real
widespread
Steve -
For the first end site that has to connect via IPv6,
it will be very bad if there is not a base of IPv6
web/email sites already in place.
While there are going to efforts to recover unused
IPv4 space, we're currently going through 10 to 12
blocks of /8 size
