Change IP address of your computer in few steps

Click on "Start" in the bottom left hand corner of screen.
Click on "Run".
Type in "command" and hit ok.

Now the MS-DOS prompt screen will appear in your window.

Type "ipconfig" after the prompt and hit "enter".
(If you have an IP address already for your computer, it will list the IP address)
Type "exit" and come out of the MS-DOS prompt screen.

Right-click on "Network Places" or "My Network Places" on your desktop.
Click on "properties".

You should now be on a screen with something titled "Local Area Connection".

Right click on "Local Area Connection" and click "properties".
Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab.

Click on "Use the following IP address" under the "General" tab.
Now you are ready to create an IP address. (fill in the area with the IP address that you need)
Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.
Hit the "Ok" button here.
Hit the "Ok" button again.

You should now be back to the "Local Area Connection" screen.

Right-click back on "Local Area Connection" and go to properties again.
Go back to the "TCP/IP" settings.
This time, select "Obtain an IP address automatically".

Hit "Ok".
Hit "Ok" again.
You now have a new IP address for your computer.

Pls Note:

This only changes your dynamic IP address, not your ISP/IP address.
If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back.
