ttdnsd is just a transport relay for dns over tcp with no real knowledge of
DNS(SEC). It would be much better to use a DNSSEC aware nameserver, so avoid
needing to rely on Tor Nodes or directory servers. Not to say the least about
trustig google(!!!) of all places with anonymity.

I have no idea about what "first" and "second" mode you are talking about.
