Abstract
A router obtains a network address generated by a PC connected to a LAN, and the identification data (MAC address) unique to the PC. When the obtained network address does not match the network address (EUI-64) generated from the obtained identification data unique to the PC according to a predetermined rule, the router sends a collision message.
