Where to buy Internet IP addresses

Tue May 5 21:19:58 UTC 2009

Jumping in against my better judgment ...

The /64 boundary was for a number of reasons, the fact that "only" autoconfig breaks when that isn't the case is irrelevant (and not entirely true, but many of the breakages are minor/not intractable).

Complaining about it now doesn't help, and many other decisions have since been made that rely on /64s. 

So, half-assed or not - this is the protocol we have, and it works today ... So what is the operational debate?

Ah, but they half-assed the solution.  IPv6 makes no distinction between  
network and host (eg. "classless"), yet SLAAC forces this oddball,  
classful boundry.  Routing doesn't care.  Even the hosts don't care.  Only  
the tiny craplet of autoconfig demands the network and host each be  
64bits.  That's brilliant!
