I managed to get reverse DNS resolution to work. However, it would be nice to have forward DNS resolution on subnets as well. I can't seem to find anything about this in the FAQ. It seems pretty logical and straight-forward to have something like <myhost>.<tunnelname>.sixxs.net where I would be responsible to provide resolution for the 'tunnelname' part (assuming tunnel names are unique globally). Ofcourse, I could register a 2nd-level domain but 3rd-level domain would be enough. Am I really missing something or should I propose this to the sixxs staff?
