The 2k server thinks that it's maintaining the reverse map for the various
10.1.x/24 blocks it's responsible for.  Indeed, if you ask it about those
it gives the right answers.  Trouble is that the OpenBSD boxes don't want
to ask it -- they just say "we don't know" :-(

named.conf makes it primary for 10.1/16.  I *thought* that should allow me
to delegate the various 10.1.x/24 ranges to another server -- presumably
this is what our ISP has done with the "real" class C block that we're
happily serving the reverse lookups for.

I know, I should just go buy the book and learn how to do this properly :-)
