I notice that too. If both A and AAAA are sent and there is a response 
for A and NXDomain for AAAA

musl-libc discard both results. It's the expected behaviour according to 
this commit:

And it conform to

It's was not the case before Alpine-Linux 3.13

But I also notice that if the DNS reply ServFailed instead of NXDomain 
for AAAA request, musl-libc retry 10 times, return 'bad address' and do 
not fallback to return a A record.

According to 
it's not expected.
