Valid IP numbers for custom-nameservers

[Estibaliz Alvarez]

Hope this is the right place to post this. If not, sorry!!

I want to allow my clients to insert their own nameservers in the form,
but the code has no restriction regarding the entry in those fields. I
mean, you can enter whatever you want, numbers, any characters,
punctuation marks, etc, and nothing complains. Does anybody have a patch
which validates IP addresses? I guess it should be implemented in the
"validate" procedure in XML_Client.pm

Thanks
