ISP communities

Hi there, Is there any web site summarizing communities defined by major ISP? I'm looking for UUnet (AS701), MCI (euhh C&W sorry) (AS3561), BT (AS5400). Of course, their communities are not published in the whois database, like UU europe (AS702), Ebone (AS1755), Swisscom (AS3303). TIA, Cheers. -- Philippe Strauss, ingenieur systeme/reseau, Urbanet SA philippe.strauss@urbanet.ch tel +41 21 623 30 20 --
