When your computer joins to a network or the Internet, it receives an IP address just like any other computer. Your computer’s IP address is a unique address and identity. The IP address system is used to identify and recognize computers on networks (or the Internet in general). As a result, no two computers on the same network (or the Internet in general) can (or should) share the same IP address in principle.

What is the source of the warning “Windows has discovered an IP address conflict”?


A unique number – an IP address – is given to each device that connects to the network, allowing it to be identified and interacted with. As a result, no two devices may have the same IP address in theory. In reality, though, interference is always a possibility. Because of a malfunctioning router, computer settings, or even issues with the Internet service provider, two or more devices may share the same IP address.

In this situation, Windows attempts to inform you that several devices use the same IP address, which may cause connectivity issues. As a result, the error message “Windows has discovered an IP address conflict” will appear. Because the device is unable to connect to and communicate with the network, this is a serious mistake. As a result, it must be addressed right away.

The good news is that the “Windows detected IP address conflict” issue is a very frequent problem with a variety of solutions.
