why?? are you doing something illegal?? No ,its not.........once you login to THEIR network........they see it because you are given an IP address.........

How it is illegal , could u plz. explain it ??
Give me specific reason.

320mb was just asking if you're doing something illegal that you want to hide.

Any way, there are various levels of anonimity that you can have. You could for instance only log into sites that are protected by SSL and that would prevent your ISP from knowing what you're looking at, but it would not prevent them from knowing what the IP address is of sites that you're visiting. You could also set up all your traffic to go through a proxy on a different network, so your ISP would only know that you're using a particular proxy (or set of proxies).

The problem with what you're asking is that you don't control whether other sites use SSL or not, and for a proxy strategy to work, you must have viable proxies for every type of traffic you send (HTTP, SMTP, NNTP, etc). Also, proxies only protect you from your ISP. The ISP of where ever the proxy is can see incoming requests (at least the source IP) and can see what the outgoing requests are in total.
