From my under standing (correct me if im wrong) but isnt your intial login point on the internet is already logged by your ISP?
That would be my understanding also. Certainly it is the way my connection works, as it uses my telephone line, which is uniquely identifiable. I cannot connect from another line because it matches my account to my telephone number.

If I messed with the IP address that my ISP gave me then I might be able to connect, but the ISP wouldn't know where to send the replies? I think that 127.0.0.1 would find rather a lot of computers in the World, and would be a one-way conversation? ............. I would expect that situation to provoke some sort of error condition, as it cannot be correct?

I must admit that I find this whole thing a little confusing, because if you don't trust your ISP why are you doing business with them?
