Could you make an option for the user to decide whether to get the A result or the AAAA result or the result of ANY? Not everyone has an ipv6 address. Those who don't have a native ipv6 address have to use a tunnel. And your software is very good.However, your software has only a backup mechanism and no complementary mechanism.which makes the software somewhat inadequate. If you can do it ,I would be appreciate

That would be breaking standards IIUC. It sounds like you are using some non-standard environment. If you only have IPv4, your host shouldn't be trying to use AAAA records. ANY queries return both A (type 1) and AAAA (type 28) records. Your host should choose the most appropriate.

Yes, I am using a 6in4 tunnel, which is why I need to use a DoH service with different EDNS client subnets such as first ECS A is where my ipv4 address,and last ECS B is ipv6's . I thought I could force it to accept only one of the results returned by ipv4/6 by adding type=1 or type=28 before parsing the URL, but I failed. It seems that their order determines ipv4 and ipv6 results by the first ECS A ,I sincerely hope that users can choose different ECS that ipv4/6 should use.
