SYSTEM FOR NUMBER OF IP ADDRESS SHARING CLIENT, METHOD FOR PERFORMING THE SAME, AND COMPUTER READABLE MEDIUM STORED THEREON COMPUTER EXECUTABLE INSTRUCTION FOR PERFORMING THE METHOD

摘要

PURPOSE: A system and a method for monitor an IP(Internet Protocol) sharing client number, and a recording medium storing a program are provided to monitor the client number sharing an IP address without entering the inside of a private network sharing the IP address. CONSTITUTION: A network management tool(40) carries out the network connection management in order to communicate with a WAN(Wide Area Network)(30) based on a TCP/IP(Transmission Control Protocol/Internet Protocol) protocol forming the private networks, and collects a TCP/IP packet from a client. An IP sharing monitoring tool(50) reads an IP packet ID code included in each IP packet by collecting the IP packet inputted to the parallel-connected network management tool, and calculates a number of an increasing set of an ID code by comparing the continued IP packet ID codes with each other for each monitored ID address.
