What it sounds like is one of the following: 1) They got confused with 192.168.xxx.xxx networks when setting it up. 2) They got 192.255.xx.xx from some group that said they could have it when they couldn't 3) They grabbed it a long time ago and don't remember they did so. 4) Some combination of the above. In any of the cases, its their local network which is foo-bared one way or another. Their local routers must have had a route to it and no longer does.. getting a traceroute from them or something to show where their router thinks it should go (or if they have an old one to show where it was.) > -- > Hector Herrera > President > Pier Programming Services Ltd. > > -- Stephen J Smoogen.
