Comment (by nickm):

 Hm. I'm trying to reproduce the bug with DNSPort, and getting strangeness.

 I started Tor with "./src/or/tor -dnsport '9999 preferipv6automap'
 -automaphostsonresolve 1 -automaphostssuffix .  "

 Then I did:
 {{{
 [619]$ dig @localhost -p 9999 aaaa www.torproject.org

 ; <<>> DiG 9.8.3-P1 <<>> @localhost -p 9999 aaaa www.torproject.org
 ; (3 servers found)
 ;; global options: +cmd
 ;; Got answer:
 ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 45384
 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

 ;; QUESTION SECTION:
 ;www.torproject.org.            IN      AAAA

 ;; ANSWER SECTION:

 }}}

 and

 {{{

 ; <<>> DiG 9.8.3-P1 <<>> @localhost -p 9999 example.com

 }}}

 I'm not seeing the behavior where it answers AAAA for every request. In
 fact, it seems to be sending A even if it was asked for an AAAA.

 How do I reproduce the behavior that you are talking about?
