Thanks *every one of you* who replied / helped.
So it turns out to be a no-issue, just I didn't understand the proper
way to use `dig`.

Good question, I do remember that I configured my network interface
(eth0) via NetworkManager *on the server side*, but I don't recall
doing anything on the client side. Maybe I'm taking everything by
default? How can I confirm that?
- my "/etc/network/interfaces" is not touched, still contains nothing
- I do have a "/etc/NetworkManager/system-connections/Wired\
connection\ 1" file, but I have no recollection whether I created it
or system created it for me.
- I do remember, when things "didn't work out", I installed the
'resolvconf' package again -- previously I always remove it without
seeing much side effects.

So my "/etc/resolv.conf" is controlled by 'systemd-resolved', but I
have no idea what/how 'systemd-networkd' is/works. hmm....

This is the fist time I am hearing this! as the content on the
Internet will tell you to add this or add that, without telling you
why. So if I want to keep my *client* system clean, without mixing
them and not having extra packages, what shall I do? Would staying
with systemd (not NM) work? (for normal cases like taking my Laptop
Further on that, seems to me previously Ubuntu use
NetworkManager+dnsmasq.base for local DNS caching, but now it is
moving to pure systemd based as well, for local DNS caching, right?
All in all, what's the recommended way to configured my network
interface of my client system with modern Ubuntu/Debian?
