then, you can have (if you want) another bind listening on other
interfaces for other stuff.  like the "internal dns" server that you
mentioned.  or maybe a recursive, caching-only server that listens
only on 127.0.0.1.  of course...they can speak to each other if need
be.  :)

I tried 2 instances of BIND and they didn't work right.  One functioned
and the other played dead (very dead ... as in the process blocked and
would not wake up).  One needs 2 separate machines to get it to actually
work right (times the amount of redundancy desired).  If you know the
magic to make it work right, I'd sure like to know.  Maybe some kind of
lock somewhere?

Works great here. You need to make sure that each bind instance has its
own set of named.conf/zone files/pid file/ndc channel, that they bind to
different interfaces. I also like to force them to have different query
ports, but this shouldn't be necessary as long as they are on different
interfaces.
