What is a Proxy Server?
The technical definition for "Proxy": The technique in which one host, usually a router, answers Address Resolution Protocol (ARP) requests intended for another machine. By "faking" its identity, the router accepts responsibility for routing packets to the "real" destination. Proxy ARP allows a site to use a single IP address with two physical networks. A proxy is a server that will act as the "middle-man" between you and whatever else you connect to. It is most commonly used as a "safety net" for your connection. Using a proxy usually hides the true identity of the person using it.
