Hi Mauro.<br><br>Got any ideas on a generic mechanism for finding the AS numbers of a network from a client PC? It seems if you can RSH into a router, then it's pretty easy to determine, but most users don't have RSH access to a router any place. It seems as though this information should be available, but I've been unable to determine exactly where or how. Of course, the AS number doesn't really help determine geographic location, but it does help determine network boundries - which would be a most interesting piece of information to add to Ping Plotter's graphs.<br><br>Thanks!<br><br>
