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:
