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

86400 ; default_ttl
)
;
NS public.r65.org.

34.219.64.in-addr.arpa. IN NS public.r65.org.
33.34.219.64.in-addr.arpa. IN NS public2.r65.org.

33.34.219.64.in-addr.arpa. IN PTR public2.r65.org.
35.34.219.64.in-addr.arpa. IN PTR r65gate1.r65.org.
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
