Displaying IPs - exposing rogues!

[bladechob]

Hi I'm currently using the script

<?php 
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) { 
echo $_SERVER['HTTP_X_FORWARDED_FOR']; 
} else { 
echo $_SERVER['REMOTE_ADDR']; 
} 
?>

to display ip address and any proxy - but it only seems to generate a 'random' ip from somewhere along the server path (I tried it myself using a proxy address and it came up with some German ip!)

 

Is there a definitive way of establishing the genuine visitor IP? I want to deter people using nicked credit card info to purchase my stuff.

 

Thanks

There's no reliable way to be sure your user's IP is real.

 

I can bounce my IP off 8 proxies before I hit your site and you'd have no idea what country I'm from.
