How to Flush an IP Address

You can flush your IP address by following a few simple steps.

An IP address is much like a home address. It's a unique number assigned to each computer connected to the Internet , an ID of sorts for your machine. If you are experiencing problems and errors with your IP address, or if you want to change it for protection purposes, the process is quite easy, especially for those who are technically-minded.

Instructions

Windows

1. Turn your computer on, and select the "Start" button. This button can usually be found on the lower-left side of your screen.

2. Select "Run" from your Start menu once it pops up.

3. Type "cmd" in the prompt in the "Run" window.

4. Look for the cmd program to pop up. It will look like a small black DOS window. Type "ipconfig/release" in the prompt.

5. Type "ipconfig/renew" in the prompt. Doing this will flush your IP address and replace it with a new one.

2. Select "View"and "Network."
