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
Pinging cisco.com [72.163.4.161] with 32 bytes of data

ping www.cisco.com

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.
