     This simple JavaScript code demonstrates how to use JavaScript in conjunction with SSI to display the user's IP address.

I found this interesting JavaScript code that can be used to reliably display the user's IP, whether in a form box or elsewhere on the page, by saving the IP in a variable. It requires that the page be Server Side Includes (SSI) enabled for the actual IP detection portion to work

<script language="JavaScript">
//IP address display: By http://www.Host
//     route.com
//Script featured on JavaScript Kit (htt
//     p://www.javascriptkit.com)
var ip = '<!--#echo var="REMOTE_ADDR"-->'
    function ipval() {

window.onload=ipval </script> <form method="post" action="" name="myform"> <input type="text" name="ipaddr" readonly> </form>

Here's a demo of the script:

This is not javascript, it's SSI You can do the same with PHP instead of SSI: var ip = '<? echo $REMOTE_ADDR; ?>'
