  function(data){
       ip = data.ip;
alert(ip); //return ip address correctly
  });
alert(ip); //undefined or null

Answer 1

This will set the IP Address to a hidden input field.

<script>
ip = null;
$.getJSON("http://jsonip.appspot.com?callback=?", function(data) {
    ip = data.ip;
    $("#getip").val(ip)
    alert(ip); //return ip address correctly
});
alert(ip); //undefined or null
</script>

<input id="getip" type="hidden" />
