1. Disable `systemd-resolved` if you want to use plain `resolv.conf`.
2. Either use router's DNS: Restart machine to have and updates `resolv.conf` file.
3. Use dedicated DNS, e.g. see [https://www.kuketz-blog.de/empfehlungsecke/#dns](https://www.kuketz-blog.de/empfehlungsecke/#dns) or your own.
4. Edit  `resolv.conf` by making it immutable afterwards: `sudo chattr -i /etc/resolv.conf; sudo nano /etc/resolv.conf; sudo chattr +i /etc/resolv.conf`

    ```shell
    options timeout:1
    options single-request
    # IPv4
    nameserver ...
    # IPv6
    nameserver .............
    ```
