摘要

Disclosed is an IP sharer detecting and intercepting system and method. According to the IP sharer detecting and intercepting method, all the IP packets transmitted through the network are detected, an ID value of the IP header is extracted from the detected IP packets, and an IP sharer user is estimated based on the number of states of ID values for the same IP. A notice packet is transmitted to the estimated IP sharer user to detect a private IP of the IP sharer user, it is determined whether the IP sharer user uses the IP sharer based on the detected private IP, and the checked IP sharer user's Internet connection is intercepted. In this instance, a notice packet for introducing an entrance to a normal cable is generated to the IP sharer user before the checked IP sharer user's Internet connection is intercepted.
