Hm...one could also write a 'shortened-form-detection' and let PHP
expand them before actually validating them (does that make sense at all?)
Maybe vice-versa you can also write a function (which probably already
exists somewhere) to shorten your IPv6 addresses before displaying them
in the web interface - that way you have "complete" IPv6 addresses in
your database but your web interface does not get cluttered with tons of

The only problem I had so far happens with MX and CNAME records:
they may not contain IP adresses, but a hostname my contain dots and
numbers - which leads to a quite complicated regex (e.g. allow whatever
a regular hostname can contain BUT fail if it looks like an IPv4 address)
