I can not get reverse DNS working, forward works great. When I do I reverse
I get *** localhost can't find 64.219.34.34: Non-existent host/domain. When
I do a dig @ns1.sbwell.net I get the follow:
****************************************************************************

So I am an authority for this in-addr.arpa, so why is it not resolving? Here
is a copy of my /var/named/db.64.219.34 file:
****************************************************************************

$TTL 86400
34.219.64.in-addr.arpa.         IN      SOA     r65.org.

                        10800 ; refresh
                        3600 ; retry
                        604800 ; expire
                        86400 ; default_ttl
                        )

34              IN      PTR     public.r65.org.
****************************************************************************

What I find confusing is my upstream DNS provider told me to add an
in-addr.arpa db for 32.34.219.64.in-addr.arpa, but this is the broadcast
address for my little 5 usable ip subnet so there is nothing to assign to
this.

Thank you very much
