This mean over 57% of the routing table consists of /24s. So in order to
facilitate getting this fixed, I have prepared a list of the worst

not being aggregated. If all of these entries could be aggregated (and I'm
certain this simple script missed some), it would reduce the routing table
by over 29,000 entries, to less the 78k. I think it's pretty obvious that
a lot of these simply have no excuse.

I'd suggest you review your data. Checking our AS (7657) you list networks
we havn't had for 6 months advertised to a peer we havn't had for 3
months.

Not to mention you don't even list a bunch of /24s we are advertising
(for various reasons (not all good)).
