Abstract: To study the space distribution and the transmission mode of network traffic in P2P network, this paper analyzes and evaluates the IP address geomapping technique. The advantages and the principle of the technique are present with comparing different network location acquirement techniques. A simple random sampling method is implemented to evaluated the most popular IP address geomapping data-base. Results show that the accuracy rate of province-level locations is 100%, and the accuracy rate of city-level locations can achieve 98.40%. It proves the reliability of the technique.

Key words: Peer-to-Peer(P2P), network measurement, location awareness, geomapping
