| IMO the easiest way to do input validation is assigning a Regex to each

The current trick used in pdnsadmin is to validate IPv4 with:
~        function is_valid_ip($ip)
~        {
~                return( $ip == long2ip(ip2long($ip))) ? true : false;
~        }

If my understanding of the PHP manual is correct this would work for
both IPv4 and IPv6 if one uses inet_pton and inet_ntop instead.

But the annotated manual said there is an issue with the detection of
some address forms in those routines. So it may not work as well as
expected. I need to think on this a bit more and test it a lot before I
submit patches.
