You mean 66.20.53.128/27, I believe.

The name of the domain that has been delegated to you is
128.53.20.66.in-addr.arpa, not 128/27.53.20.66.in-addr.arpa.  Get rid of
the /27 in the zone statement.

You see how much easier it is for us to advise you once you tell us the
real info.

Get rid of the /27 here.  Or get rid of the $ORIGIN statement entirely
(it's redundant, since the origin defaults to the zone name, and putting
the same thing in two places is a good way to cause problems if they get
out of sync).

Add NS records for your ISP's secondary servers:

         IN      NS      ns2.cl.bellsouth.net.
         IN      NS      ns3.cl.bellsouth.net.

>128     IN      PTR     amril.net.

Replace "128" with "@", since the .128 entry is actually the zone name.
