Question: How to troubleshoot duplicate ip address?

If you defined a static IP address for a network device, duplicate IP address conflicts may occur on a DHCP network. See more details. To resolve it, convert the network device with the static IP address to a DHCP client. Or, you can exclude the static IP address from the DHCP scope on the DHCP server.

Moreover, what happens when you have a duplicate IP address? If you mistakenly assign the same static address to two devices, you’ll run into a duplicate IP error. This problem can also arise if you set a device to use a static IP without reserving that address in your router. Eventually, your router will try to hand out that address to another device, creating an IP conflict.

People ask also, why is there a duplicate address detected for the IP address? NOTE: A Duplicate IP Address error message occurs when another device, such as a Laptop, Desktop, Cell Phone or Tablet has connected to the Network, and obtained the same IP Address from the DHCP Server that is in use by the Printer.

Similarly, can 2 devices have the same IP address? An IP address conflict occurs when two or more devices on the same network are assigned the same IP address. … Because of this setup, no two devices can have the same IP address on one network. If this happens, the network becomes confused by the duplicate IP addresses and can’t use them correctly.

Quick Answer, how do you check if there is a duplicate IP address on network? Here is how you can check it: On an unaffected host on the same network, open up a command prompt. On a Windows machine, type “arp -a [suspected duplicate IP]” and hit enter. On a Mac or Linux machine, type “arp [suspected duplicate IP]” and hit enter.The most common subnet you will see is 255.255. 255.0. So if two addresses match in the first three sections (reading left to right), and the subnet is 255.255. 255.0 for both addresses, they are in the same subnet.
