Well, first of all, an empty file will at least give you a nice clean
fail, and won't refer the request to a root server! I'm sure the people
who run the root servers don't appreciate all the crap that sites like
yours must throw at them all day long.
Second, it is trivial to write a script to generate all possible ranges.
