  <p>I need to let my users find very quickly and easily their local (LAN) ip.</p>
  
  <p>Our network has a squid proxy so all the users sit behind it (and this is a problem for internal ip detection: all php scrips I've tried are able - at best - to detect proxy's ip and not client's).</p>
  
  <p>Any kind of language working on a LAMP server is welcome...</p>
  
  <p>Also a simple EXE file on Windows could work as "plan b" but I couldn't find anything working.</p>
