I run unbound (full version) on one of my servers.  All my systems are entered into it's database as local-data in local-zone.  All the systems use that system for DNS.  If the internet is down, local DNS still works.  I don't the RDNS entries and haven't needed them.  If they are necessary, unbound can do that also.
