To do this, you need to edit file with name hosts on your computer. Add following content to it.

NEW_IP_ADDRESS www.yourdomain.com yourdomain.com

Example

127.0.0.1 www.serverok.in serverok.in

At this point, if you take command promt on you computer and type folloing command, you will see the new server IP.

ping www.yourdomain.com
