I don't think I did a good job describing the situation.  I run
so I don't have to use my ISP's DNS since it's broken, often.  It's
just a recursive DNS for my LAN.  I'd like to have reverse mapping
working.  But right now it's not working.  Is my setup out of the
ordinary?  Is no one else doing this?  I guess everyone has slightly
different reasons for running a DNS but I didn't think my reasons were
a corner case.  My question comes down to this.  How do I set this up
so that I get reverse-mappings when I need them?

Also any pointers on getting caching to work (using gqlite) for
positive and negative queries
would be much appreciated.
