It may be legit on your network, but people generally don't do that.... If they publish a aaaa record, it usually has a legit v6 address in it.
That is a legit IPv6 address. That it won't work on a host that is IPv6-only is a different issue, and one I agree is probably an unexpected and unwanted side effect.
This doesn't sound like a host issue, but a broken dns64 implementation. If it checked the content of the aaaa response for an ::ffff... answer and treated that as an A-only response, the host would never be involved. Tony
