How To Fix Ip Address Conflict In Your Pc

You may have encountered the problem Windows has Detected an IP Address Problem when many of your devices are connected to your home network. Once this happens, you will either lose your network connection, or it will not be stable.

Why Does This Problem Occur?

Your PC will have a unique IP address. Every PC on a given network has it as this is the only means to which the router can track from where a particular request, the new web page is coming as well as where the information that we get from the Internet is arriving at.

The IP address is assigned to your PC by the Dynamic Host Configuration Protocol (DHCP) server that is already present in your router. DHCP consists of some IP addresses from where it assigns them to the different devices that are connected to that particular network.  However, what happens sometimes is that this DHCP gives the same IP address to two different devices. After one of the devices have received the IP address, and after working for some time it is kept in sleep mode, the DHCP senses that device is not being put to use, gives the same IP address to the second device. The problem of conflict in IP address arises when the first device is again put to use, and it uses the IP address used by the second device. 

It can also happen that the same IP address is given to multiple devices connected to the same network. This happens when the DHCP starts malfunctioning.
