To change the computer’s IP address open a Control Panel and navigate to “Network and Internet à Network and Sharing Center”
Then when the Network and Sharing Center opens, click on “Change adapter settings”. This will be the same on Windows 7 or 8.x. Right-click on your local adapter and select Properties.
In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button.
Now select the radio button “Use the following IP address” and enter in the correct IP, Subnet mask, and Default gateway that corresponds with your network setup.
Now close out of the Local Area Connections Properties window.
Now you can open the “Command prompt” and do an ipconfig to see the network adapter settings have been successfully changed.
