This is an auto-generated mail on Fri Nov 1 12:00:00 PST 1996 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me. In the future I hope to put some (or most) of this report up on the web. ------------------------------------------------------------------------------ CIDR REPORT for 01Nov96 0) General Status Table History ------------- Date Prefixes 261096 41599 271096 41493 281096 41624 291096 42078 301096 42058 311096 41986 011196 41917 Possible Bogus Routes --------------------- *** Bogus 90.0.0.0 from AS4747 AS Summary ---------- Number of ASes in routing system: 1732 Number of ASes announcing only one prefix: 702 (362 cidr, 340 classful) Largest number of cidr routes: 493 announced by AS3561 Largest number of classful routes: 1534 announced by AS174 1) Gains by aggregating at the origin AS level --- 01Nov96 --- ASnum NetsNow NetsCIDR NetGain % Gain Description AS174 1534 1093 441 28.7% Performance Systems International AS3602 621 333 288 46.4% Intergrated Network Services Inc.
