Abstract
One or more LAN switches capable of accessing the contents of a MAC address table, which the LAN switch contains, from the outside; and a presence server storing in a storage device a first correspondence table between a MAC address of a network interface, which equipment contains, and its user, and a second correspondence table between a port of the above-described LAN switch, and a physical range wired therefrom, are used to thereby obtain a correspondence table between the equipment, its user, and its physical location (range), whereby making applicable also to a wired LAN at the time of determining the location of the equipment or the location of a user using the equipment in a building, and making realizable at low cost, and allowing the location to be determined accurately within a predetermined segmented area, and not being affected even if an IP address is changed.
