In fact, it's one particular vendor (whose name I haven't been able to discover) of pay-for-Internet transparent proxy/NAT devices, such as those commonly used in hotels and at hotspots, that's messing the whole thing up. They return an address of 0.0.0.1 in response to any DNS query from an IPv6-capable client, and they've decided to train their service providers' tech support departments to tell customers to turn off v6 rather than fix what should be a very simple bug.
(Granted that's a passable workaround for a few months while a vendor prepares a patch, but this issue has been around for _years_.)
I know it is always fun to blame M$ but really it isn't true.
Agreed. MS is sending a proper query, and every other DNS server on the face of the planet responds correctly. There are a few random apps that still bomb when both ends have IPv6 and there's only a v4 path between them (though most have been fixed over the last few years), but the OS is working correctly.
