    I take the opportunity to tell that I checked Fennec's config and
it seems to have DoH disabled, as I'd expect.

    Maybe dnsmasq features a DHCP service, but it is not enabled in my
configuration. Not that this is like a systematic test, but, when I need
to ssh to the desktop and it is off, then I just power it and, after a
minute it's address name is resolved. I think I'd rather suspect the
thing works with Linux machines thanks to avahi-daemon. I couldn't find
anything on the web about the DNSSEC protocol on Android; this is
frustrating, but, after all, wifi on these engines is a goodie while
they are primarily designed for GSM.
