Information processing device, address duplication handling method, and computer-readable non-transitory recording medium

摘要

A sensor device 20 includes a terminal detection unit 21 that detects a terminal connected to a network segment 2, a duplication detection unit 22 that detects duplication of IP addresses by comparing an IP address used by a detected terminal 10X that has been detected by the terminal detection unit 21 with a predetermined IP address, and a notification unit 23 that notifies a notification object terminal 10B that could have been notified of a MAC address of the detected terminal 10X by this detected terminal 10X, of a MAC address of a terminal other than the detected terminal 10X, when duplication of the IP addresses has been detected by the duplication detection unit 22.

主权项

1. An information processing device comprising:
a processor programmed with executable instructions causing the processor to operate as
a terminal detection unit to detect a terminal connected to a network;a duplication detection unit to detect duplication of upper layer addresses by comparing an upper layer address used by a detected terminal that has been detected by the terminal detection unit with a predetermined upper layer address; anda notification unit to notify a notification object terminal that could have been notified of a lower layer address of the detected terminal by the detected terminal, of a lower layer address of a terminal other than the detected terminal, when duplication of the upper layer addresses has been detected by the duplication detection unit, wherein the duplication detection unit detects duplication of the upper layer address used by the detected terminal and an upper layer address of the information processing device, and the notification unit notifies the notification object terminal of a lower layer address of the information processing device when duplication of the upper layer address used by the detected terminal and the upper layer address of the information processing device has been detected by the duplication detection unit.
