1. Check your router’s DHCP log. Many routers have a log that shows all of the IP addresses that have been assigned to devices on the network. If a device is assigned the same IP address as another, this will appear in the log.
2. Use a network scanning tool. There are a variety of network scanning tools available that can scan the network for duplicate IP addresses.
3. Check the ARP table. The Address Resolution Protocol (ARP) table stores the mapping of IP addresses and MAC addresses. If two devices have the same IP address, they will both appear in the ARP table.
4. Use a command line tool. On Windows, you can use the “arp -a” command to display the ARP table, and on Linux/Unix systems you can use the “arp -n” command. This will display a list of all IP addresses and their corresponding MAC addresses. If two devices have the same IP address, they will both appear in the list.
