That's higher than my number! I was more conservative and said 2^21.
Even 2^26 is a effectively an AS per 5 people on the planet, even if the
population quadruples within the lifetime of IPv6, that's one per 20
people on the planet. As I said, it's not a bet I'd take, I like
overprovisioning by orders of magnitude, but that should really bring
home how ridiculously big the number space is. Oh, and even if we
totally mess up, we've burned a /3, there's a few more where that came
