Hi,


if you are running a phpbb board, here is a useful hack to give a whatismyip dot com like service

search at phpbbhacks dot com website
"what is my ip address"

Regards,
Ferman

Or just use PHP, so much easier, just a line of code....

<b>IP Address is:</b></h2><H1>

<?php
//Obtain IP Address
$ipaddr = getenv("REMOTE_ADDR");
echo $ipaddr;
?>

start, run, cmd, "ipconfig /all"


Or

start, run, cmd, "ipconfig /all >C:\Documents and Settings\%username%\desktop\MY IP.txt"
The file will appear on your desktop as a text file :)

Or...
<h2><strong>IP Address is: </strong></h2><h1><?= $_SERVER['REMOTE_ADDR'] ?></h1>

We're talking about displaying it on websites....

The PHP super global $_SERVER['REMOTE_ADDR'] contains a visitors IP address, so it is very easy just to use it. Works very well.

REMOTE_ADDR will work unless the visitor's ISP puts them behind a proxy. If that's the case you might have to use HTTP_X_FORWARDED_FOR to get their true IP.

in that case, what is the full code to check it?

If a user isn't behind a proxy I don't think you get anything from HTTP_X_FORWARDED_FOR so it might be best to do something like:

if there is an HTTP_X_FORWARDED_FOR
echo HTTP_X_FORWARDED_FOR
else echo REMOTE_ADDR

Maybe someone can put that into PHP code for you.

This covers all bases:


function GetUserIP()
{

if (isset($_SERVER))
{
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"]))
{
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
elseif(isset($_SERVER["HTTP_CLIENT_IP"]))
{
$ip = $_SERVER["HTTP_CLIENT_IP"];
} else
{
$ip = $_SERVER["REMOTE_ADDR"];
}
}
else
{
if ( getenv( 'HTTP_X_FORWARDED_FOR' ) )
{
$ip = getenv( 'HTTP_X_FORWARDED_FOR' );
}
elseif ( getenv( 'HTTP_CLIENT_IP' ) )
{
$ip = getenv( 'HTTP_CLIENT_IP' );
}
else
{
$ip = getenv( 'REMOTE_ADDR' );
}
}


return $ip;

}


Hope it helps!
