No. I don't think anyone can find your house through your ip addy. They can figure out your isp and general area, but not exact location. That's why the recording companies had to sue ISP's for customer info a few years back. Only your ISP knows where you live and unless you download some kiddie porn or blockbuster movie, they won't tell no one.

At least that's how I understand it. I welcome anyone to explain how I'm wrong.
