How To Change Your Pc's IP adress

There are MANY methods to change your IP address. Some methods will work for you but may not work for someone else and vice versa. We’re going to cover how to change your IP address in Windows 2000, XP, 2003, and Vista using command prompt.


What Is An IP Address Lease Time?

An IP lease time is the amount of time your ISP determines you’ll be assigned a particular IP. Some IP lease times could be just a couple of hours, where some are set to a few days, and other IP lease times could be set for as long as a year or more. This setting is completely up to your ISP.

One of the easier methods to change your IP address is to turn off your modem/router/computer overnight. Then turn it back on the following morning. This method WILL NOT work if your ISP has a long lease time set for your IP.

The following method will ONLY work if your computer is being assigned your external IP and not a router.

If your connection is direct to your computer and your computer gets the public IP and not a router, you can try this:
