PROBLEM TO BE SOLVED: To avoid waste of a node address by assigning the address on the occurrence of communication between networks. SOLUTION: Upon the receipt of a SYN packet, an address assignment request generating module 31 of a router assigns an address and sends an address assignment request 32 to an address assignment module 33. The address assignment module 33 assigns a proper address and informs it to a routing module 35. The routing module 35 records routing information to a routing able with respect to the assigned address. A node sends a FIN packet of a TCP protocol. When the router receives the FIN packet, an address release request generating module 36 sends an address release request 37 to an address release module 38. The address release module 38 releases the address assigned to the node and informs it to the routing module 35. |
