Yup, you are right. I managed to pick the only service actually
discarding the address provided. It's a protocol thing, their protocol
doesn't allow anything but using the addresses visible from afraid.org.

I have learned some things about this since my original post. This mess
inspired me to write ddupdate[1], a in my eyes more sane updating client
than ddclient. These kind of mistakes just shouldn't happen using this.


Cheers!
