How to get client / user ip address?

Question

Is it possible to get the ip address of the user (visitor of my website) without using server side language like PHP?

I have a problem while using the server language (PHP) because of load balancer for my server. I tried http_x_forwared_for that is also not retrieving the perfect ip address.

Answer 1

Try this:

$.getJSON("http://smart-ip.net/geoip-json?callback=?", function(data){
   alert(data.host);
});

Answer 2

function get_client_ip() {
    $ipaddress = '';
    if (getenv('HTTP_CLIENT_IP'))
        $ipaddress = getenv('HTTP_CLIENT_IP');
    else if(getenv('HTTP_X_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_X_FORWARDED_FOR');
    else if(getenv('HTTP_X_FORWARDED'))
        $ipaddress = getenv('HTTP_X_FORWARDED');
    else if(getenv('HTTP_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_FORWARDED_FOR');
    else if(getenv('HTTP_FORWARDED'))
        $ipaddress = getenv('HTTP_FORWARDED');
    else if(getenv('REMOTE_ADDR'))
        $ipaddress = getenv('REMOTE_ADDR');
    else
        $ipaddress = 'UNKNOWN';

    return $ipaddress;
    }

IN PHP :)
