> Up until January 1 2010, ARIN distinguishes between 2-byte and 4-
> byte ASNs, and lets you have a 2-byte if you need it, but gives out
> 4-bytes otherwise, to spur adoption.
> After January 1 2010, ARIN ceases to make any distinction between 2-
> byte and 4-byte ASNs. Instead, they simply give out ASNs as they

> out will be <64k. Eventually, when that block of ASNs is used up,
> they'll move on to higher numbers >64k. Presumably by then everyone

More importantly, by then, it really doesn't matter since there aren't
any 16-bit ASNs left to give out.
