There is such a thing as private addressing where you can have any address you want, but you usually have something set up at the router that dynamically assigns you an address space when you leave your network, such as out in the internet world. That way you remain legal... And the addressing within your network is your own business then. I do not know how this actually works, but I do know this is an option. I think I read something about NAT providing this service. The group would know about this. I do not. Chuck is a good one to ask on this issue... The question is how come someone can have a class a address that internic did not assign. Anybody?? Jen ------------------------------------------------------------ Have a Good Day!!
