Subject: Re: getaddrinfo() fails for domains with no AAAA records (regression?)
I wrote a tool some time ago that was precisely designed to work
around buggy DNS servers incorrectly returning NXDOMAIN, precisely
because such a need was expressed in Alpine.
This tool is called dnsfunnel, and is available here:
https://skarnet.org/software/dnsfunnel/
It is also available in Alpine, in testing/ - it has been rotting there
for months because I asked Alpine people to test it in situations
involving actual buggy servers (my own infrastructure is not exposed
to this problem), but my request apparently got lost in the void.
If there is motivation to actually work around incorrect NXDOMAINs,
it may be a good idea to bring this back to life and actually test
dnsfunnel in real situations where it could be useful, so it can
properly be packaged in Alpine and set up for users who need it.
