I would triply emphasize that.  Data from the root servers show that
the vast majority of queries they get are garbage: technically
ill-formed or for names that have never existed and likely never will.

That's less of a problem at less prominent servers, but even at my
tiny system hosting domains you've never heard of, I get plenty of
junk queries for things like AFSDB records and for domains I don't
