Get Unique Identity Of Pc(system) Using Javascript

Question

I am developing a JavaScript application and I need a piece of code that can identify the PC LAN IP because I want to prevent unauthorized user to access my application and main factor is PC is not connected to internet but only connected to static LAN IP so how can I achieve this?

thanks in advance.

You would normally protect your application at the server, as you have no control over modifications to your client app. — iCollect.it Ltd, Jun 19 '14 at 06:32

function myIP(){ var vi="uses java to get the users local ip number"
    var yip2=java.net.InetAddress.getLocalHost();   
    var yip=yip2.getHostAddress();
  return yip;
}//end myIP

alert("your machine's local network IP is "+ myIP());
