Domain forwarding lets you point your domain name to another home page or web site location. Forwarding is handy when you have a web site built elsewhere and you want to give people an easy-to-remember domain name to reach your site.
Here's an example. You can forward:
http://www.yourdomain.com >>>>>>> http://www.google.com
So when people type http://www.yourdomain.com in their browsers, they'll see http://www.google.com
