The Top 20 and some deltas

9 Nov 1994

      This is an auto-generated mail on Wed Nov  9 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-20.09Nov94

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Please also find a summary of the last weeks changes in terms of withdrawn and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This a daily snapshot of changes in classfull routes being withdrawn and added.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.
