Abstract: Disclosed is a peer to peer (P2P) network system in the present specification. A peer activity management server (PAMS) of the P2P network system receives inquiry whether the PAMS controls a peer from another PAMS or receives status information of the peer or service use or content of the peer from the peer or another PAMS. Further, the PAMS determines whether the peer is controlled based on the inquiry by the PAMS or updates a peer list based on the service use or content of the peer. In addition, the PAMS transmits the status information of the peer included in the peer list to an overlay management server or transmits the service use or content of the peer to a user management server.
