Hers's the /etc/resolv.conf on my davuan buster laptop:

# Generated by Connection Manager
nameserver ::1
nameserver 127.0.0.1

Now I have no problem resolving domain names, whither in chromium,
firefox-esr, or even just ping.

But a far as I know, I have never put a dns esolver on the laptop.

Does devuan do this for me?
Have I done it and forgotten?

How should I find just how dns lookup is done on my machine,
and how should it be done?
