Network switch and method of preventing IP address collision

摘要

A network switch and a method of preventing an IP address collision is provided. When a new node tries to use an IP address, which is being used in one broadcast domain, it is possible to detect and prevent an IP address collision in real-time, disconnect only the new node which caused the IP address collision, and quickly resolve network environment to the original state that existed prior to the collision, in order to prevent communication breakdown without the use of an additional device.
