Abstract

To allow to specify a network apparatus to which an illegitimate apparatus is connected and its connected port. In the case of detecting an illegitimate connection of an apparatus 31 connected to a repeater hub 42, a connected position specifying apparatus 10 collects the correspondence relation between a MAC address and a port stored in switches 21 to 26 and repeater hubs 41, 42 for returning a response with respect to a network management request, specifies a port P2 of the repeater hub 42 to which the apparatus 31 is connected on the basis of the collected correspondence relation between the MAC address and the port, and externally outputs the specified port P2 of the repeater hub 42.
