HTTP 1.1 requires a Host: header field; this way, multiple web servers may  
share the same IP address. So you can't identify a host by its IP alone;  
the host name is required. This was devised in order to save IPv4  
addresses; LACNIC (the Latin America addresses register) does not assign  
addresses to ISP's based solely on web hosting anymore - they MUST share  
existing IPs. And I think a similar policy is used on other regions.
