perhaps, remember that japan has +100m 'users' on them islands, eh?
"we are planning a dsl network rollout to the home island of japan,
expected subscriber base is 15M users conservatively"
now I get a /8. simple, see? :)

Actually, I think it'd be GOOD if the v4 space got very scarce very
fast... it'd make people stop putzing around with v6 amd mae it production
for real. (perhaps even someone would think about how to multihome in v6?
in a workable manner)

So, makes you wonder:
1) comcast doesn't care about subscribers getting 'partial' connectivity
due to acls/bogon-filters/blah
2) comcast fights this battle silently, with battle hardened network
ninjas, silent killers of bogon filtering
3) the mythical bogon filtering 'problem' isn't really a problem?
(sort of poking fun, mostly being serious...)
