indeed, and a firewall such as norton's Personal Firewall will actually tell you the city the IP is located in. It is remarkably accurate for what i've seen. (It told me what hotel cheyenne was staying in during some xperiements.) Well it told me where the domain resided, and the DNS was under "something HILTON HOTEL, and the address. Of course that will not be the case for personal computers, instead it will mention where the server is located.

I've actually been getting scanned for netBus from the same IP in my ISP for the past week...and its not a zombie. Norton tells me he's in Cambridge, but if I put my IP there, it will say the same...which is the city next to me.
