The Top 20 and some deltas
- Date: Wed, 31 Aug 1994 21:10:11 +0200
This is an auto-generated mail on Wed Aug 31 21:10:00 MET DST 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-20.31Aug94
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Please also find a summary of the last weeks changes in terms of withdrawn and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 chuck of classful routes.
This a daily snaphost of changes in classfull routes being withdrawn and added.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.
