DNS fallback behaviour

In u-OS, the systemd service systemd-resolved is used for name resolution via DNS. The following DNS servers are configured as default fallback servers:

To prevent usage of the default DNS servers, you can configure your own DNS servers. If you did not configure DNS servers, the system automatically selects one of the systemd default servers as a fallback. Should your DNS server be unreachable, the system will not revert to any of the default fallback servers.
