Okay, this would have to be done in code, and isn't a MySQL issue.
Presuming you're using PHP, I'm going to also copy this message to
the PHP General mailing list, Payne, so that others can benefit from
it in the archives as well. If you're not already subscribed and
would like to follow along with the thread, please send a blank
message to php-general-subscribe@xxxxxxxxxxxxxx
To get the Class C on that, here's a simple function you can use:
<?php
function get_subnet($ip) {
return substr($ip,0,strrpos($ip,'.'));
}
?>
As a quick illustration of how it works, here's an example script
(to use MySQL, just replace the $ips array with your <?php $row =
mysql_fetch_array($result); ?> or similar line):
<?php
$ips = array('192.168.0.0','10.0.0.1','127.0.0.1','216.37.159.240','99.99.99.99','127.0.0.2','192.168.1.1','10.0.0.0','192.168.0.1','192.168.0.150');
function get_subnet($ip) {
return substr($ip,0,strrpos($ip,'.'));
}
foreach($ips as $ip) {
echo $ip."'s Class C is ".get_subnet($ip)."\n";
}
?>
