 A while ago we had a user on irc who had a DnsPort and a SocksPort,
 transparent proxy style. He went somewhere that his dnsport resolved to an
 IPv6 address:

 https://gitweb.torproject.org/tor.git/tree/src/or/dnsserv.c?id=6cb1daf062df525224ee7e3f7cd63ee858aacf9f#n147

 But then later he tried reaching that address and his vanilla Socksport
 line didn't specify it could handle ipv6, or maybe it was some other
 issue, but in any case he ended up with this confusing warning message:
 {{{
     log_warn(LD_EDGE, "I'm about to ask a node for a connection that I "
              "am telling it to fulfil with neither IPv4 nor IPv6. That's "
              "not going to work. Did you perhaps ask for an IPv6 address "
              "on an IPv4Only port, or vice versa?");
 }}}

 Maybe this bug is fixed already. Or maybe this person wasn't fully
 explaining his situation. But I figure it's better to file it than to
 leave it sitting in a browser tab for another two weeks.

 Feel free to triage to 0.2.7 or to close if you think it's nonsense by
 now.
