Unfortunately this doesn't seem to be possible currently, since at the
end of the circuit creation the exit node replies with a single IP and
TTL [0].  (Tor is TCP-only, hence not suitable to route DNS packets; DNS
resolution is left to SOCKSv5 server [the tor client], which in turns
delegates it to the exit node.)

There is a proposed amendment to the Tor protocol [1] to support full
DNS (and DNSSEC) resolution, but the proposal is still sketchy and has
never been implemented.
