    How does systemd-resolved interact with `/etc/resolv.conf`?

    On modern Linux, systemd-resolved manages DNS. The /etc/resolv.conf file is now just a link to a local stub resolver (127.0.0.53). This stub forwards all DNS queries to the actual servers configured in /etc/systemd/resolved.conf. Therefore, do not edit /etc/resolv.conf directly, as the system will overwrite your changes.
