You can do a whois on the IP and you can find out what physical address that IP is registered to. I've done it on my own and the schools computers. You can try it yourself if you know your IP google whois or download the one from sysinternals.com and do a whois on your own IP to see what you get. As far as hacking unless they have some kind of trojan they really can't hack into your computer the most they can do is stalk you.

I was wrong you can find out the info of the service provider. When I tried whois out I did it at school and their ISP gives all the info about the school so I thought it was the same for homes.
