Patent attributes
A managing device includes an identification information requesting unit that requests each network interface for the identification information of all the network interfaces belonging to the image forming device via the network, and an identification information receiving unit that receives reply information from the each network interface in response to the identification information request. When the identification information receiving unit receives a plurality of pieces of the identification information, an identification information equivalency judging unit judges whether a combination of the plurality of pieces of the identification information received from one of the plurality of network interfaces is identical to another combination of the plurality of pieces of the identification information received from another of the plurality of network interfaces. When the combinations are determined to be identical to each other, a managing unit manages the network interfaces as ones belonging to the same image forming device.
