Hey TB, neat stuff as always. A few comments for you and others below. -scott -- Tony Bates <tbates@cisco.com> wrote
AS Summary ---------- Number of ASes in routing system: 1792
Number of ASes announcing only one prefix: 737 (378 cidr, 359 classful
Wow! Is a correct assumption that some 40% of the ASs could be reclaimed?
Largest number of cidr routes: 461 announced by AS3561 Largest number of classful routes: 1266 announced by AS174
Neat stuff. Could you list the top ten or five of each of these?

I do not see how you get to this conclusion. He did not say number of ASs which only appear through one other unique AS, i.e. are single homed. Oh, Joel!

What is a 'top' prefix? Lowest IP? Shortest prefix? Actually, for embarrassment sake, I would want to see the most likely candidates for aggregation. But if I wanna see it, I can look in one of my routers.

Far out! Maybe so!

Sorry. I have to convert my RADB RPSL one into a placeholder RIPE-181++ for the MCI-RR, and that's the descr:. For the real aut-num: see the RADB. I would think Tony would be picking up the latter. Old habits, TB? randy

Old habits, TB? * The RADB doesn't keep AS information for things not in the IRR. MCI (and RIPE) takes the Internic AS allocation and massages it into a basic aut-num (you need -a flag but it is there) so I use this as it gives me a single point with the most AS to name mappings. I wonder who thought doing the Internic mappic was useful ? --Tony * randy
