I believe your answer would be:
1: Open the command prompt window. Do this by clicking the "Start" button, and then selecting "Run." In the window that appears, type "cmd" into the text box and click the "OK" button.
2: Release the computer's current IP address. To do this, type "ipconfig /release" into the command prompt window and press Enter.
3: Acquire a new IP address. Do this by typing "ipconfig /renew" into the command prompt window and pressing Enter. This should assign the computer a new IP address, which will be different from the previous address.
4: Cycle your modem's power. If the above steps don't work, you can try renewing your IP address by cycling your modem's power. Turn off both your computer and your modem (and your router, if you have one). Wait at least 5 minutes, then turn everything back on. If your computer is set to receive an IP address dynamically (the most likely configuration), you should be assigned a new IP address automatically.
5: Check to make sure your IP address has changed. To do this, you can log on to a number of different websites that tell you your IP address.
