1. A communication device comprising:
- a first part transmitting information to and receiving information from an adjacent device;
a second part automatically determining addresses for mounting ports of the communication device and a first port of the adjacent device so that the addresses are not duplicated, the first port being connected to the communication device;
a third part managing address information of all the mounting ports of the communication device, the first port of the adjacent device, and a network to be constructed;
a fourth part managing address determination authority to determine the addresses,wherein one of the communication device and another device in the network to be constructed is selected as a parent communication device having address determination authority to determine the addresses in the network;
a fifth part automatically selecting an unused address from the network including a port to which a terminal is connected, the port being one of the mounting ports of the communication device or a second port of the adjacent device; and
a sixth part selecting one of the communication device and the adjacent device as a managing device performing centralized management of addresses of terminals on the network,wherein said fifth part sets a DHCP server function in the communication device if the sixth part selects the communication device as the managing device and the sixth part establishes tunnel connection to the adjacent device if the sixth part selects the adjacent device as the managing device.

7. A communication device control method comprising the steps of:
-
(a) determining automatically addresses for all mounting ports of a communication device and a first port of an adjacent device connected to the communication device through the first port so that the addresses are not duplicated, the communication device and the adjacent device being included in a network to be constructed; (b) selecting one of the communication device and another device in the network to be constructed as a parent communication device having address determination authority to determine the addresses in the network, wherein the parent communication device manages address information of the mounting ports of the communication device, the first port of the adjacent device, and the network to be constructed; (c) selecting automatically an unused one from addresses on a network including a port to which a terminal is connected, the port being one of the mounting ports of the communication device or a second port of the adjacent device; and (d) selecting one of the communication device and the adjacent device as a managing device performing centralized management of addresses of terminals on the network, wherein said step (c) sets a DHCP server function in the communication device if said step (d) selects the communication device as the managing device and said step (d) establishes tunnel connection to the adjacent device if said step (d) selects the adjacent device as the managing device. - View Dependent Claims (8, 9, 10, 11, 12)
