If you selected DNS Server during the task selection on installation
(of the original Debian, whatever that was) you got bind9. dnsmasq must
have been manually installed at some point.

It can also use root hints, without asking any other DNS server. I'm
not sure if there's any other DNS server in the Debian repositories
which will do that. Many public DNS servers do things other than
honestly return results or 'not found'. Google barefruit dns.

I once had a fairly reputable router which would not resolve *some* MX
records. That was a pig to track down, and I still don't know how that
could happen.

There may be bind9 client bits installed on computers which do not
use bind9, and I'm guessing should probably not be removed.
