Yes, you can get it, but I wonder: why?

i have proxy server its giving me proxy ip not my machine IP

That's what a proxy is supposed to do...

You can try checking the Forwarded address - but very few proxies set it, because it pretty much makes using a proxy rather pointless!
There is some code here that does that:

But if that doesn't work, it's by design...

Hi,

Try following.

JavaScript

<script type="text/javascript" src="Scripts/jquery-1.6.2.js"></script>

 <script type="text/javascript">

     $.getJSON("http://jsonip.appspot.com?callback=?",

    function (data) {

        alert("Your ip: " + data.ip);

    });

 </script>
