Heh. I didn't really doubt that you understood the math. Was just
being a bit snarky. :p (this whole thread is sort of flame bait anyway
Anyway, with just 2000::/3 alone, there's about 500 million /32s.
According to the CIDR report, there's ~34,000 ASs in BGP right now.
Lets double that "for future growth" just for fun. If we do that, it
means if we divided those /32s evenly among all of those ASes, each
would get about 7800 of them. Each one contains 64Ki /48s. And again,
that's just one /3 of the entire v6 space (yeah I know they won't be
divided evenly ... different sizes orgs, regional assignments, etc, etc,
Anyway, I think the addy space will tide us over for quite a while, even
if it's "not enough" as your last post seemed to indicate. Hey, and if
we ever do run out, we can just NAT! ;) ;) ;)
