A terminal connected to a network stores association information between a physical address and a logical address of the terminal as first association information in an address association information storing unit. The terminal obtains association information between a physical address and a logical address, which is transmitted to the terminal via the network, as second association information. The terminal determines, based on the first association information stored in the storing unit and the second association information, whether or not the logical address included in the first association information is duplicate. If the logical address is determined to be duplicate, the first association information is notified to a device belonging to the network to which the terminal belongs, and the device is instructed to resolve duplication of the logical address.
