I think, *that* is called a search algorithm. Try it at root level, with
WinNT, you'll find that it doesn't work. Better yet, try it with BIND8
(*nix, of course) too, and compare the results.
If your test doesn't produce the same results, please send test-plan,
scripts, and methods to me. I'd be very interested.
