Abstract
In a communication device for carrying out communications according to an Echonet protocol on a network of a prescribed network layer protocol, a prescribed bit sequence value of a network layer address or a datalink layer address of the communication device is set as a candidate for an Echonet address to be used in the Echonet protocol. Then, an inquiry packet for inquiring whether the prescribed bit sequence value is identical to the Echonet address used by each other communication device or not is transmitted, and the prescribed bit sequence value is determined as the Echonet address of the communication device when the prescribed bit sequence value is judged as not identical to any of Echonet addresses used by the other communication devices.
