Manual Setup

Want to update the DNS server in your favorite Linux distro? Well, there are only about 20 ways to do it. But in all seriousness, if you require a tutorial to do this, it may be a better idea to use the Automatic Setup method. It abstracts the setup to a single command.

We'll briefly go over some common ways to update DNS.

systemd-resolve

If you are running a version of Linux that uses systemd-resolved, you can likely configure DNS-Over-TLS on it.

Open Terminal and edit your resolved.conf file

nano /etc/systemd/resolved.conf

Update your config as follows if you are using a custom premium resolver. abcd1234 will be different for you.

[Resolve]

DNS=76.76.2.22#abcd1234.dns.controld.com

DNSOverTLS=yes

The value of DNS after the # will be your DNS-over-TLS resolver for the chosen Device. Save the file and restart the systemd-resolve service.

stubby

If you're using stubby, edit the config file.

sudo nano /etc/stubby/stubby.yml

Find round_robin_upstreams and set this value to 0.

Then search for DEFAULT UPSTREAMS and and comment out all of them. Then add a new entry. abcd1234 will be different for you.

- address_data: 76.76.2.22
  tls_auth_name: "abcd1234.dns.controld.com"

The value of tls_auth_name will be your DNS-over-TLS resolver for the chosen Device. Save this file and restart stubby.
