pinging a domain name

Experts,

I've noticed that when you ping a website by WWW and without WWW, the reply is different.  Can someone explain why?

ping cisco.com

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Diffferent servers, different IP. You can decide yourself if you want domain.com or www.domain.com to be the same server or not. Domain admins decide that for themselves.
In this specific example, cisco.com has a simple webserver, ONLY to forward you to www.cisco.com (which is really the server holding the complete website). Cisco.com probably has other functions as well, while www.cisco.com probably has the sole function of serving the website.
