-------------------------------------------------+-------------------------
From #10465: 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:
www.torproject.org. 60 IN A 127.237.144.204

}}}
and
{{{
[621]$ dig @localhost -p 9999 example.com
; <<>> DiG 9.8.3-P1 <<>> @localhost -p 9999 example.com
; (3 servers found)

example.com. 60 IN A 127.201.101.133

}}}
It seems to be sending A even if it was asked for an AAAA.
(There are deeper DNSPort+IPv6 issues going on, of course, but this part
is probably easier, and it's an independently useful bit of
functionality.)
