title: Identify local PC with JQuery
body: <p>Im trying to identify a PC to check on the amount of login attempts.</p>
  
  <p>At the moment im using code to identify the IP address of the PC. </p>
  
  <p>It works well, but if you are using a dynamic IP of you encounter a bot that changes its IP every second or two, it wont work.</p>
  
  <p>Here is the current code</p>
  
  <blockquote>
  <pre><code>&lt;script type="application/javascript"&gt;
      $(document).ready(function() {
          $.getJSON("http://www.telize.com/jsonip?callback=?",
              function(json) {
                  myIP = json.ip;
              }
          );
      });
  &lt;/script&gt;
  </code></pre>
  </blockquote>
  
  <p>Is there some other unique address or code that I can grab? (like MAC address, but I know that is not allowed.)</p>
