The client system uses DNS to translate “volokh.com” to “174.37.144.148″ and sends the HTTP request to that address. While at the TCP/IP level, the packet is not addressed to “volokh.com”, the web client includes an HTTP HOST header that specifies “volokh.com”. When the web server (Apache in this case) receives the HTTP request, it looks at the HOST header and decides which content to serve based on that. So when I browse to http://174.37.144.148/, it gets to the same web server, but it does not know that I am looking for the “volokh.com” content and serves content based on the defaults.

Is this correct?
