I have no idea, I think I have read it is *hardcoded* into systemd-
resolved, but I didn´t check, so take this with a grain of salt. It seems
you can only disable this behavior by configuring a DNS server.
>From resolved.conf(5):
FallbackDNS=
A space separated list of IPv4 and IPv6 addresses to be
used as the fallback DNS servers. Any per-interface DNS
servers obtained from systemd-networkd.service(8) take
precedence over this setting, as do any servers set via
DNS= above or /etc/resolv.conf. This setting is hence only
used if no other DNS server information is known. If this
option is not given, a compiled-in list of DNS servers is
used instead.
Okay, it depends whether it is possible to set this on a zero value.
If that doesn´t work it may work with setting it to 127.0.0.1 or even
a non existing 127.0.0.0/8 address.
I set it to an empty value now. But how do I get confirmation that it
works? Do I really have to deconfigure DNS to find out?

I didn´t even report the bug, but I was surprised how Marco just closed it
as wontfix. But on the other hand I see a pattern there. I have seen that
with systemd related bug reports as well.
Its more this "I won´t fix this, go away" attitude I have seen with
systemd upstream and with Debian packagers of systemd than systemd itself
that lets me ponder to avoid systemd at least for my server VM.
Thanks,
