IP address is a unique address your computer gets when it connects to a network. It’s the computer’s address and identity which is used to identify it among all the other computers and network devices. This error, as you can see in the message, shows that the IP address you have is in use. Usually, this is a Private IP Address and has nothing to do with your Internet Provider since it is a glitch with your PC Settings or Router. All Private IP Addresses on your network must be unique.
Think of it as a postal address, let’s assume you have 4 devices connected (a computer, a printer, an iPad and an iPhone) to your Network, a message is sent from somewhere destined for the iPad but the iPad and the Computer have the same IP (Address). Now how is the Post Man supposed to know which of the two is the correct recipient?
Now let’s proceed with troubleshooting the issue.
Method 1: Restart Your Router
Your router can be failing to assign an appropriate IP address to the connected device. This can be caused by a temporary glitch, but most of the time this is cleared by a simple reboot/power cycle. To do this, switch off the router, wait 1-2 minutes and turn it back on. Once it’s on, give it another 2-3 minutes to settle, and then connect your device back. This will refresh the DHCP server of your router and it will assign a new IP address to all the devices connected to the router.
Method 2: Release and Refresh IP Address
Click Start and type cmd, right-click cmd and choose run as administrator.
In the black command prompt window, type the following commands and press Enter after each:
netsh int ip reset c:\resetlog.txt
Now test to see if the issue has been resolved.
Method 3: Remove Static IP
Press and Hold Windows key and press R. In the run dialog type ncpa.cpl and Click OK
Right-click on Local Area Connection if you are using a wired internet connection or Right-click on Wireless Network Connection if you are using Wi-Fi. Click on Properties in the drop-down menu.
Double click on Internet Protocol Version 4 (TCP/IPv4). Select Obtain an IP address automatically.
Select Obtain DNS server address automatically. Click OK > OK and close all windows.
Restart your system and check if the issue resolved.
