Following screenshot is from a Windows operation system detecting an IP address conflict. As I mentioned in this article ( ), the station or the server may check if the IP address is already in use and prevent the conflict. There are chances that the statically configured printer IP address can be assigned to another station. Not all DHCP servers check if an IP address is already in use before assigning it to a station. The idea of assigning a static IP address sounds good but it has a caveat.

Otherwise, it would be difficult to use the printer if its IP address was assigned dynamically by the DHCP server in a couple of days. Since it was a network printer, you thought it was a good idea to assign a static IP address to it so that your colleagues can also use it. Imagine you bought a printer and introduced it to the network in the office. However, most of IP conflict happens due to configuration mistakes. Otherwise, an IP conflict arises when two devices on the same network have the same IP address.Īn IP conflict can happen for a variety of reasons.

It is very important that an IP address has to be assigned to only one station in the network.
