unwanted DNS requests to localhost:53



Hey list,

I am working offline and couldn't help notice that my applications
still try to resolve DNS hostnames.

There are no routes, no addresses of any kind, and all interfaces --
except lo -- are down. avahi-daemon is not running, and
/etc/resolv.conf is empty.

I noticed that /etc/nsswitch.conf includes mdns stuff, so I removed
that (I certainly am not a friend of this kind of
auto-configuration), and now it just says: "hosts: files dns".

Yet, when I ping debian.org, tcpdump sees 2 (!) DNS A requests to
127.0.0.1:53.

Where are the coming from? How can I tell that source to stop trying
to be smart; if there were a DNS server on the loopback address, I'd
have configured it in /etc/resolv.conf. But I did not, and I run
Debian because I like to be in control of things. So what's going
on, and how can I restore the norm?
