DNS over TLS on Arch Linux
20 Aug 2020
Domain name resolution is not standardized, some application use NSS, some use D-Bus, others use stub resolvers.
systemd-resolved handles all of them and comes with systemd that Arch Linux uses.
systemd-resolved configuration file is at
/etc/systemd/resolved.conf, yours should look like this:
[Resolve] DNS=22.214.171.124 FallbackDNS=127.0.0.1 ::1 Domains=~. #LLMNR=yes #MulticastDNS=yes DNSSEC=yes DNSOverTLS=yes #Cache=yes #DNSStubListener=yes #ReadEtcHosts=yes
You should enable the
sudo systemctl enable --now systemd-resolved
Since you are probably using NetworkManager,
you should tell it to use
systemd-resolved by going to its configuration file (
This is how your
/etc/NetworkManager/NetworkManger.conf should look like:
[main] plugins=keyfile dns=systemd-resolved
You will probably need to restart your computer for changes to take effect.
