A method and system for entering the address of an address server to plural terminals connected to a switch, selecting a target address and switching to a substitute address server when a failure occurs in the target address server. In the invention when the switch is activated, its address management section generates a logical network table. Next when each terminal is activated, its address processing section generates a server address table and informs the switch of the address and the logical network of the terminal and whether the terminal is an address server. The address management section of the switch registers this information to logical network table. When another terminal is activated and informs the switch of its address and logical network, the address management section of the switch registers the information to its logical network table, and checks whether the address server of the other terminal has been registered. If the address server of the other terminal has been registered, the other terminal is informed of the address of the terminal and the address is registered to the other terminal. The other terminal informs the terminal of the address of the terminal other using the address of the terminal and the terminal registers this address.
