P2P Tools
An anonymous P2P computer network is a particular type of peer-to-peer network in which the users and their nodes are pseudonymous by default. The primary difference between regular and anonymous networks is in the routing method of their respective network architectures. These networks allow for unfettered free flow of information, legal or otherwise.
