Abstract
A network address supply system includes terminal equipments, a server, and a switching HUB to which the terminal equipments and the server are connected via communication lines. Each terminal equipment includes an address supply requesting unit. The switching HUB includes interfaces, a first line data storing unit, and a communication line control unit that when one of the interfaces receives an address supply request broadcast packet from one of the terminal equipments, transmits the address supply request broadcast packet to only an interface corresponding to the interface information stored in the first line data storing unit. The server includes a network address storing unit and an address supplying unit that when receiving the address supply request broadcast packet, broadcasts an address broadcast packet containing an unused network address stored in the network address storing unit as a response packet to the address supply request broadcast packet.
