Many thanks, Marc - that's a good tip. I'll have
forgotten it tomorrow, though, so I agree with Christian's
plea.

Christian,
For the ARIN database (and some others), try not adding "AS" before the
AS number, as in:
% whois -h whois.arin.net 11042
Orion Network Systems, Inc. (ASN-ONSI-NET1)
2440 Research Blvd., Suite 400
Rockville, MD 20850

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A summary of the last weeks changes in terms of withdrawn and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.
