I'm talking about those generic IPs that  router gives out, like 192.168.1.1 or 192.168.2.200 for example. From reading online alot of people state it is impossible, however, 'http://www.whatsmyip.org/more/' will give out the router IP, for example mine, on that website states 'Internal (LAN) IP: 192.168.1.68', which is correct.

I'm not certain how this can be replicated, I'm not looking for the real IP, I am looking the the internal/router IP. Any suggestions on how this can be achieved?

Right now using basic PHP/Javascript, can call any apache vars if needed too.

It's a server variable, $_SERVER['REMOTE_ADDRESS'].   They are listed there.  This short PHP page will show all the $_SERVER variables that are available from your server.

<body><h1>PHP Server Variables</h1>
<?php

//reset($_SERVER);
foreach($_SERVER as $key => $value) {
    echo "<b>$key :</b> $value<br />\n";
}
echo "<hr>";
echo "<b>ENVironment variables.</b><br>";
foreach($_ENV as $key => $value) {
    echo "<b>$key :</b> $value<br />\n";
}

?>

For the internal address you can use the script from this site:

http://www.reglos.de/myaddress/MyAddress.html

It has a MyAddress.class Java program will get the local IP address (192.168.1.x, for example.)

Here is a link to a demo page that gets the address of your computer.  http://www.reglos.de/myaddress/demo3.html


This is what the whatsmyip.org site uses.

Hope that helps.
