Re: How can I get the serverName in a servlet?

I believe that request.getLocalAddr() returns the IP address

So if you connect to localhost you get localhost and if you connect to
the real host you get the real host.

This seems rather logical to me since the host may have no real
IP address or 10 real IP addresses

Assuming you have a newer Java version you can get all IP
addresses with:

         Enumeration<NetworkInterface> e =
NetworkInterface.getNetworkInterfaces();
         while(e.hasMoreElements()) {
             NetworkInterface ni = e.nextElement();
             Enumeration<InetAddress> e2 = ni.getInetAddresses();
             while (e2.hasMoreElements()){
                 InetAddress ip = e2.nextElement();
                 // do something with ip.getHostAddress()
             }
         }
