From manual page: http://www.php.net/filter.examples.validation
---

<?php
$ip_a = '127.0.0.1';
$ip_b = '42.42';

if (filter_var($ip_a, FILTER_VALIDATE_IP)) {
    echo "This (ip_a) IP address is considered valid.";
}
if (filter_var($ip_b, FILTER_VALIDATE_IP)) {
    echo "This (ip_b) IP address is considered valid.";
}
?>

This (ip_a) should be: This ($ip_a)
This (ip_b) should be: This ($ip_b)

Have a look at the expected output:

| This (ip_a) IP address is considered valid.

That wouldn't match for $ip_a. Of course, the output could be
changed, but what would that be good for? The example already
shows, that the first IP address is considered valid, while the
second is not.
