I'm not too good at networking stuff and would be glad if someone could give some pointers.
Recently, I had a debate with my friends. The topic was about whether a person is "tracable" via his IP address assuming he is using a dial up account and a proxy server, give the IP address and the time of login.
My friends argued that IP logging is like having a used train ticket. He said that even if we have the train number, the time of boarding etc, we won't know who excatly was on the train, unless a intensive and time consuming search is made.Futhurmore, he insisted that proxy server users are almost impossible to trace due to the high destination traffic information per day.
1) Are any of his claims true ?
2) Then, assuming it's possible to trace someone(who uses a dial up account and proxy servers), how do we go about tracing ?
Thanks for any answers - I need them quick, this question is driving us crazy
