Duplicate IP addresses occur when two or more devices on a network are assigned the same IP address. This can cause conflicts and disrupt network connectivity. To avoid these issues, it’s crucial to check for and resolve duplicate IP addresses promptly.
There are several methods to check for duplicate IP addresses on a network. One common approach involves using the Address Resolution Protocol (ARP) table. The ARP table maps IP addresses to their corresponding Media Access Control (MAC) addresses. By examining the ARP table, network administrators can identify devices with duplicate IP addresses.
