We don't have those policies. Supposed-to-be-globally-routable /48s do
already exist.

If we really consider crippling CIDR lookups to less than 128 Bit:

I don't think that "64 bit or bit 48" makes much of a difference in
terms of router scalability... but I'm guesstimating here with about
nothing to back that. Other folks might comment.

ACK. And our job is to design something desireable, not something that
has serious shortcomings compared to IPv4 (no PI for endusers).
