Shame IPv4 Users!

To add this box to your page, insert the code below the examples. All of them are on a transparent background. The only differences are the font color and whether the IP address is shown.

PHP Source Files

If you want to do this yourself, feel free! Here's the PHP I used for ip5.php, my favorite:

<div align="center" valign="middle">
<small><font color="white">
Your IP Address is
<strong><?php echo $_SERVER['REMOTE_ADDR']; ?></strong>
<br>
<?php

if (preg_match("/:/", $_SERVER['REMOTE_ADDR'])) {
echo "You've got IPv6!<br>";
echo "<a href='http://attack.samsclass.info/shamev4.htm' target='_blank' style='color: #ffffff;'>More information</a>";
} else {
echo "You still use IPv4 :(<br>";
echo "<a href='http://attack.samsclass.info/shamev4.htm' target='_blank' style='color: #ffffff;'>More information</a>";
}

?>
The others are trivial modifications.

Counters

I realized I could collect data on views over IPv4 and IPv6. (I don't collect anything else intentionally.) So I modified the script to this:

<div align="center" valign="middle">
<small><font color="white">
Your IP Address is
<strong><?php echo $_SERVER['REMOTE_ADDR']; ?></strong>
<br>
<?php

if (preg_match("/:/", $_SERVER['REMOTE_ADDR'])) {
echo "You've got IPv6!<br>";
echo "<a href='http://attack.samsclass.info/shamev4.htm' target='_blank' style='color: #ffffff;'>More information</a>";

$my_file = 'countv6';

} else {
echo "You still use IPv4 :(<br>";
echo "<a href='http://attack.samsclass.info/shamev4.htm' target='_blank' style='color: #ffffff;'>More information</a>";

$my_file = 'countv4';
}


$fp = fopen($my_file, 'c+');
flock($fp, LOCK_EX);

$count = (int)fread($fp, filesize($my_file));
ftruncate($fp, 0);
fseek($fp, 0);
fwrite($fp, $count + 1);

flock($fp, LOCK_UN);
fclose($fp);
