Fortunately there are 'only' 65k ASN's, thus that would mean only 65k routes in the routing table, which should be quite practical. Seeing only ~650 routes now I don't see that happening that soon, especially with the slowness of deployment of IPv6 in the US, though it is catching on ;). Left to wonder though what happens when we run out of ASN's, 32bit ones?
32bit ASNs are already in the works. I would expect not more than 2-3 years before you see widespread 32bit ASN code in routers.
Hmmmm: Routing Table Report 04:00 +10GMT Sat 13 Nov, 2004 Analysis Summary ---------------- BGP routing table entries examined: 150665 Prefixes after maximum aggregation: 88779 Unique aggregates announced to Internet: 71952 Total ASes present in the Internet Routing Table: 18421 <---- 30% usage and we need 32 bit ASNs? -Hank
