Now i was wondering of what there might be the best way to validate an
IPv6
address.


from this url..
http://phpro.org/tutorials/Filtering-Data-with-PHP.html#9

<?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";
}
?>
