There's no single/reliable way to determine the implementer and/or
version of the DNS server by querying it via DNS.  Best way would be to
track down the machine by IP address, find its owner, and ask them.

Not sure it's still enabled by default, but BIND can be queried like so:

`dig +norecurse @$BIND_NAMED_SERVER CH TXT version.bind.`

Other implementations may have their own methods, if at all.
