while i am not "totally convinced," i am certainly concerned.  we are
doing many of the same things all over again.  remember when rip forced
a homogenous, often classful, mask length in a network and we chewed
through /24s?  think /64 in ipv6, except it's half the bits not 1/4 of
them.  remember when we gave out As and Bs willy nilly?  look at the
giant swaths of v6 we give out today in the hopes that someone will
deploy it.

and don't bs me with how humongous the v6 address space is.  we once
though 32 bits was humongous.
