Abstract: Abstract: The appearance of new applications such as Internet advertising sets forth requirements for the position on accurate understanding of network entities, and IP Geolocation technology can meet this demand. This paper introduces the basic concepts of IP positioning technology and related applications, describes the existing IP Geolocation technology, and then proposes a IP Geolocation method based on network path measurements. The method estimates the geographic location of IP by measuring paths and delay from observation point to destination IP, converting the measurement packet size inferred path distance and combining the relationship of paths. This paper establishes a experimental environment, carries out experiments using the method and compares it with other methods. The results show that this method can geolocate IP more accurately.
