ok, we can merge that to parts together.
I thought about that writing a method that validates, if it doesn't 
validate, for v6 there isn't anything to do more. Thuch a method could 
work in the head for t3lib_div::cmpIP() for switching the two protocol 
versions, the next part could be to normalize the address.

Possibly to ways for the problem, but I think a simple "is a valid IPv6"
could be reached fastest with a regular expression.

That is part of my motivation (all the bugs concerning ipv6).
