AS690 was originally aquired by Merit for the NSFNET T3 network
and subsequently assumed by ANS --> AOL --> UUNET --> WorldCom
(I'm not entirely sure if this ordering is correct).
I've nagged Lee Howard a couple times to get this transferred
over. Perhaps I need to go through a less busy person.
Well, here is an email I sent last month that didn't result in a single response - either human or auto-response:

Subject: Global routing table bloat - AS690
Cc: "Barry Raveendran Greene" <>,

AS690 has been lately seen to be sending out too many prefixes not based on CIDR boundries, thereby increasing the global router table size:

ASnum NetsNow NetsCIDR NetGain % Gain Description
AS690 513 319 194 37.8% MERIT-AS-27 Merit Network Inc.

See and and
for further details.

I hope you can take the time to add the appropriate BGP filters so that the we all do not suffer from global router table bloat.
