even if you tried contacting the isp it would be a dead end.. I know this because I'm a dunner.. and my account leads nowhere.
I could always try to locate your ISP, they are normaly within a good distance from you. I havea a dynamic IP adress, however my isp uses a static gateway, but luckly that gateway's server is located just outside of my city, I've use AO's IP locater to find it .

I can't find you with what I can find.
