There are many reasons why a person would want to change his or her IP address. This tutorial will show you how to change the IP address of a wired or wireless computer, not the IP address of an internet connection. (To do this, you need to contact your service provider.) Read on to find out how to change your IP address on both a Windows and Mac computer.

Open the Control Panel. Go to Network And Internet → Network and Sharing Center → Change adapter settings.

Right click on the internet connection that you are using. (Your internet connection may be called "Local Area Connection" or "Wireless Internet Connection.") Click properties. If prompted, type in an admin code to continue.

Find the Networking tab. Open it, and click on the Internet Protocol Version 4 (TCP/IPv4). Press the Properties button.

Under the Networking tab, click on the Internet Protocol Version 4 (TCP/IPv4). Press the Properties button.
