Firefox has for a long time done both A and AAAA lookups even if the =

Now you're counting DNS servers. Because the provisioning of IPv6 DNS =
addresses has been such a mess and still is problematic, many dual stack =
systems do this over IPv4. And the DNS servers they talk to may be =
IPv4-only, or IPv4-only users may talk to dual stack DNS servers.
In my opinion, looking at this kind of stuff in order to draw =
conclusions about what you should do is a waste of time. It just means =
more work for everyone and it doesn't fix any of the broken stuff that's =
out there.
If the results of world IPv6 day are as we expect and only 0.1 - 0.2 % =
or less of all people have problems, I think the best way forward would =
be to have a second world IPv6 day where we again enable IPv6 =
industry-wide but this time we don't turn it off again.=
