Where do you get this? There are more than 25000 AS numbers out there.
At some point, most of those networks will want to run IPv6.

It is very easy to get an AS number: if you want to multihome, you
qualify. It's not even very expensive: $500 in the ARIN and APNIC
regions last time I checked and no charge from RIPE if requested through
a RIPE member. The hard part about multihoming in IPv4 is the address
space. But if an AS number automatically means IPv6 PI space, that part
won't be a problem either.

This is what we in Dutch call an "open einde regeling" (open end
arrangement): you know where it starts, but you can't know where it ends
and thus how expensive it will be.

What's the alternative? Say to the 64511th person to request an AS
number we're all out?
