Re: The Choice: IPv4 Exhaustion or Transition to IPv6

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, ostensibly to solve a very 
specific scaling problem.

So, go ahead and continue talking about migration while ignoring the very policies within which that is permitted to 
take place and don't let me interrupt that ranting.

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
