INFORMATION PROCESSING DEVICE, ADDRESS OVERLAP HANDLING METHOD, AND ADDRESS OVERLAP HANDLING PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent a problem which can be caused by overlap of high-order layer addresses in a network.;SOLUTION: A sensor device 20 comprises: a terminal detection part 21 which detects a terminal connected to a network segment 2; an overlap detection part 22 which compares an IP address used by a detected terminal 10X detected by the terminal detection part 21 with a predetermined IP address to detect the overlap of the IP addresses; and a notification part 23 which when the overlap detection part 22 detects the overlap of the IP addresses, notifies a notification target terminal 10B which can have been notified of the MAC address of the detected terminal 10X by the detected terminal 10X, of the MAC address of a terminals other than the detected terminal 10X.;COPYRIGHT: (C)2012,JPO&INPIT
