Got a friend who is having some marital problems, basically she filed a restraining order, but in order for it to be valid he has to atleast acknowledge that he knows about it. Well the other day he tried to call her at the office. The number came up as ISDN - Basically meaning it was blocked. Well he also sent her an e-mail. We have the e-mail but is there anyway to determine where it was sent from? Like can we call Yahoo? Thats what provider he used. Obviously everyone has an IP address, and most likely he is in a Hotel, and I would imagine a hotel would have a permanent address. Note - I found a site that looks up to see who the IP is registed to. But is there a way to see location? Or should I say a hotel would have its own IP subnet etc? Help?
