Remember, this just looks at the classful routes and tries to cidrize them at the origin AS level. It assumes no holes either so it's quite possible to get a lot more back. Yes there are 31K classful routes. That's either a lot of legacy or not a lot of aggregation. --Tony
Given that the routing table stood at 28000 when CIDRD was killed off, I'd say that there have either been some recent classful allocations, or a lot of ancient networks suddenly getting advertised.
