This is an auto-generated mail on Wed Nov 2 21:10:01 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.02Nov94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.
