Subject: Re: getaddrinfo() fails for domains with no AAAA records (regression?)
So you're saying that that is the registrar's fault (which also
provides the name servers)? Can you possibly tell how this can be
fixed? Other than by giving up on wildcard dns records?
A couple more points. First, apparently there was some change between
musl-1.2.2-r0 and musl-1.1.24-r10, getaddrinfo() stops working since
Alpine Linux 3.13. Which comes down to the fact that ping and ssh
can't resolve such hostnames. Although host, getent and dig can.
Second, it works on Arch Linux, Debians 8, 9, 10, and CentOS 7. The
way it looks, it works on libc, and doesn't work on musl.
Additionally I've attached the relevant part of the registrars' web interface.
Regards,
Yuri
