<!-- start: here's ip stuff --> <script type="application/javascript"> function getip(json) {  document.write(json.ip)  } </script>  <script type="application/javascript" src="https://api.ipify.org?format=jsonp&callback=getip"></script>  <!-- end: ip stuff -->    <form> <input type="text" id="ipadderss"> </form>
