Why is reverse not working?

Lisa,
I'm just guessing here but it looks like you are delegated a /26 address
space. Here is a result of my dig query for one of your addresses.
;253.157.203.207.in-addr.arpa. IN PTR
;; ANSWER SECTION:
253.157.203.207.in-addr.arpa. 43200 IN CNAME 253.192.157.203.207.in-addr.arpa.
I also checked and your ISP BellSouth shows that your names server is
authoritative for 207.203.157.192.
I admit I am not that familiar with non-octet aligned delegations (RFC
2317) but it may work if you do the following type of change for all your
records.
253.192 IN PTR ppp47.campbellcounty.com.
Depending on which Bind you are using you should be able to simplify this
with the $GENERATE directive. I suggest trying this with one or two
records before committing to a complete change.
Changing your zone to 192.157.203.207.in-addr.arpa in your config file may
also work and be simpler.
