That doesn't always work.  Take cases where multiple sites live on a 
server with one IP address.

I pinged www.gc.maricopa.edu to get their IP address 140.198.200.163.  I 
put in firefox and got their site.

I tried the same for www.foxnews.com 24.143.206.89 but got the following 
instead.


  Invalid URL

The requested URL "/", is invalid.

Reference #9.55ce8f18.1321555305.131e3b52
