**Please use a local unbound which is even better!**

Start and enable 

```shell
systemd-networkd
systemd-resolved
```

You probably want to force DNS in `/etc/systemd/resolved.conf`

```ini
[Resolve]
DNS=...

# keep this empty to fail resolving if primary DNS doesn't work
FallbackDNS=
```

**Only if you want to prevent any network manager to change DNS servers**, then execute `sudo chattr -i /etc/resolv.conf; sudo nano /etc/resolv.conf; sudo chattr +i /etc/resolv.conf` to insert the following content:

```shell
options timeout:1
nameserver 80.241.218.68
nameserver 46.182.19.48
nameserver 8.8.8.8
nameserver 1.1.1.1
```
