I apologize for my "newbie-ness" but I hope you all can help. I am trying to look up the origin location of an IP address and the only results I can come up with are the internet service provider.

68.50.*5.2**

This person posted some of my personal information and I'd like ***** down the location of the IP. I know you cannot look up a physical name but if I could get the city or state, it would really help to narrow down the search. When I run it through WHOIS, it comes up as Comcast Digital Cable.
