IPC: H04L12/28
Filed: 2002-03-12
Abstract: PURPOSE: A method for detecting IP(Internet Protocol) share is provided to prevent the deterioration of network speed due to IP share by periodically checking an IP shared state. CONSTITUTION: An IP share detecting program checks whether a network card is installed in a user PC. When the network card is detected, the program acquires the user's local IP address(S100). Based on the acquired local IP address, the program generates a search target IP address(S110). The program transmits an ICMP(Internet Control Message Protocol) traceRT packet to the search target IP address(S112). After transmitting the ICMP traceRT packet, the program waits during TTL(Time To Live)(S114), and checks whether time is out or an error is generated(S116). Then, the program judges whether the hop counter is smaller than or equal to 1(S118). If the hop counter is smaller than or equal to 1, the program acquires an IP address in normally echoed data(S120). The program compares whether the acquired IP address is identical to the search target IP address(S122). In case that the acquired IP address is identical to the search target IP address, the program stores it as an additionally used IP address(S124).
