Abstract:
An electronic device is disclosed that generates an interface identifier to determine an IP address to use. The electronic device comprises an interface identifier generating unit to generate the interface identifier, a temporary IP address determining unit to determine a temporary IP address containing the interface identifier and a prefix, a duplication determining unit to determine whether the temporary IP address is the same as an IP address of another electronic device, and an IP address determining unit to specify the temporary IP address as the IP address to use, when the duplication determining unit determines that the temporary IP address is not the same as the IP address of another electronic device, wherein the interface identifier generating unit generates another interface identifier when the duplication determining unit determines that the temporary IP address is the same as the IP address of another electronic device.
