In a VoIP network system, when a host terminal detects a link with a network, a connection-time determiner determines the time required for reconnection from a disconnection time when a link with the network was disconnected before to an establishment time when a link with the network is reestablished. If the time required for connection is shorter than a predetermined period of time, the connection-time determiner determines that address information is not to be transmitted since the time required for connection is too short to transmit the address information. Otherwise, the connection-time determiner determines that the address information is to be transmitted. According to a result of the determination, self-address information is transmitted by multicast communication to other terminals.
