FYI the host(1) command offers a MUCH simpler way of checking these sorts of things. Just a single command, and a single option "host -C zone" (or add '-u' to do the query/queries with TCP). IMNSHO host(1) is far easier to use, and far more versatile, than any other DNS query tool.
The latest version of host(1) can always be found here:
ftp://ftp.nikhef.nl/pub/network/host.tar.Z
Namespace collision! ftp.nikhef.nl has versions of programs that are very similar to "canonical" distributions but are different in option syntax and features. Usually somewhat more featureful, but not always. For instance, traceroute that differs from the canonical version (ftp.ee.lbl.gov). "host" that differs from any of the canonical versions (like that distributed with bind), etc., etc. I think promulgating their usage as long as they conflict in name with more popular versions of the same programs is A Poor Idea. --jhawk
