Doesnt filter_var() require PHP5+ ?
Yes. In fact, 5.2.3 or above, if I'm not mistaken. I know it's fine in
5.2.5. Check your servers; several are "stuck" at 5.2.2 for some reason
I don't understand and it won't work right.
HTH
I have quite some systems still running 4.4.8.

<?php
/*** an IP address ***/
$ip = "2001:0db8:85a3:08d3:1319:8a2e:0370:7334";
/*** try to validate as IPV6 address ***/
if(filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6) === FALSE)
{
echo "$ip is not a valid IP";
}
else
{
echo "$ip is valid";
