As per the article mentions of resolving AAAA IPv6 records, a feature was just merged into Linux's systemd-resolved last week. https://github.com/systemd/systemd/pull/34165 https://github.com/systemd/systemd/pull/34165 So you can do. RefuseRecordTypes=AAAA So there, your DNS won't ever query for IPv6 AAAA records. (in fact you can refuse any DNS questions like MX, SRV, TXT as well with: RefuseRecordTypes=MX SRV TXT) Note - I started adding that feature because some applications were "misbehaving" and querying AAAA records when IPv6 stack was disabled.
