Have any of your systems ever popped up with an error message concerning your IP address conflict? What internally happens is when you link your system, smart-phones, or any such devices to a local network; they all get a unique IP address. The main purpose of this is to grant a significant addressing technique for the network & its elements. This helps in distinguishing each device on the same network and converse to each other digitally.
Even though it is not something that occurs frequently, IP address conflicts are authentic problems and troubles a lot to the users. Conflicting IP address happens when 2 or more systems, connection end-points or hand-held devices in the same network wind up being allocated the same IP address. These endpoints can be either PCs, mobile devices, or other network entities. When this IP conflict occurs between 2 endpoints, it causes trouble to use the internet or connect to the internet.
How do IP Address Conflicts happen?
There are different ways a device can acquire IP address confliction.
✓ When a system administrator allocates 2 systems with the same static IP address on a LAN.
✓ Cases, when your local DHCP server assigns an IP address and that same IP address is assigned by system administrator while allocating static IP within the range of local DHCP network.
✓ When the DHCP servers of your network malfunction and end up assigning the same dynamic address to multiple systems.
✓ IP conflicts can also occur in other forms. A system may experience an IP address clash with itself when that system is configured with various adapters.
Recognizing IP Address Conflicts
The error warning or indications regarding IP conflicts will arise based on the type of machine affected or the OS that the system is running. On a lot of Microsoft Windows-based systems, you will obtain the following pop up error message:
“The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.”
For the new Microsoft Windows systems, you receive a balloon error pop up below in the Taskbar regarding dynamic IP conflicts saying:
“There is an IP address conflict with another system on the network.”
On some old Windows machines, a warning message or informative message may appear in a pop-up window saying:
“The system has detected a conflict for IP address…”
“Windows has detected an IP address conflict.”

Method 3: Set Static IP Address For Your Windows Computer Manually

5. Now, double click on “Internet Protocol Version 4 (TCP/IPv4)” option.
6. It will allow you to configure your static IP based on your details of modem or router. Below is just an example in one of such cases:
Note: If the IP address of your modem/router is different, such as 192.168.11.1, then your static IP address needs to follow its form, for example, 192.168.11.111. Otherwise, your Windows computer won’t be able to connect to the network.
IP address: 192.168.1.111 Subnet mask: 255.255.255.0 Default gateway: 192.168.1.1 Preferred DNS server: 18.104.22.168 Alternative DNS server: 22.214.171.124
