IPV6 renumbering painless?

Fri Nov 12 16:56:11 UTC 2004

Hmmm....It walks like a duck:
	Can be advertised to any v6 ISP.
Talks like a duck:
	Does not have to be returned to ISP when changing transit providers.
Floats like a duck:
	Provides globally unique v6 addresses to said organization

Must be made of wood and so it must be a witch.

I don't care whether you want to call it PI space or not, the bottom line
is that it has all the same practical uses and effect as PI space, and,
this is exactly what the real world is likely to do with v6 for any
organization that wants to multihome without renumbering.  They'll get
an AS and they'll get a /32, and, suddenly, each department within the
company will become a "customer" of the IT-ISP department.

I'm not saying this is clean, friendly, nice, whatever.  However, it is
what people are really going to do with the current v6 address allocation
policies.

If it wasn't crypto-signed, it probably didn't come from me.
