One year has passed, so it had to be done again!
The result? Pick either of these to find out what I found to be true this year, too!
This time I didn't bother to try it with IPv6 only, I just looked at the DNS results. Also, comically, my IPv6 setup at home is broken (for quite some time now), and I can't figure out what the problem with the tunnel should be. Oh yeah, I still need the tunnel, because my access provider has just not yet discovered IPv6.
