Re: who gets a /32 [Re: IPV6 renumbering painless?]

Jeroen, this is nonsense and you know it.Larger enterprises probably consist of 200 'sites' already, eg seperate offices, locations etc. Thus they can, after becoming a LIR and getting an ASN, which most of the time they already have, easily get a /32.
We've been discussing the big enterprise problem in multi6 (multihoming in ipv6) circles very extensively. At some point, I realized that the "I'm so huge I need private space" claim is false in 99% of all cases, as these organizations tend to have multiple sites (as you indicate above) but they generally do not have real connectivity between those sites. This means a single large prefix won't do them much good, and basically they're no different than a bunch of smaller single-site organizations.
Now I hate to be the bearer of bad news, but having unaggregatable globally routable address space just doesn't scale and there are no routing tricks that can make it scale, whatever you put in the IP version bits, so learn to love renumbering. And again, IPv6+NAT makes no sense as NAT works much better with IPv4 and with NAT you don't really need the larger address space.
Actually, I would even go so far that the really large corps should beIf you want to introduce geography into routing, do it right. The above "solution" is the worst of several worlds.
