Along these lines, have any of the large resolvers implemented
RFC 6975 (DAU/DHU/N3U EDNS codes)?  OpenDNS/Cisco
enabled these a couple of weeks ago but had to disable them
pending qq.com being fixed (its nameservers returned
SERVFAIL).  Now that the fix is there, we’re planning to turn
it up again at the end of the week.

Just curious about its adoption… it feels like we testing new
waters here.
