hi sander,
one would think that the goal would be to maximally get ipv4 space into play Unless we can get IPv6 completely deployed before we run out of IPv4 space, I think this should indeed be our current goal.
i think we should start a betting pool. when the last /8s are given to the rirs by iana, X percent of traffic in bits/sec measured at some easy point (say linx, amsix, or de-cix). i take X=6. yes, i am an optimist. and i do not believe that any amount of screaming, twisted policies, threats, ... will change this at all significantly, just as it does not for bcp 38, dns vulnerability patching, ... there are the folk who do things and the folk who don't. transfer is one of the few things we can do in the address policy space which may actually make a difference, albeit not a large one, but still a difference. randy
