In what zone were you searching for PTR records?  The command

     ls -d andyf.com

will not return any PTR records, because (I assume) that there are no
PTR records in that zone.   If you tried a zone transfer on a zone like
this

     ls -d 221.150.207.in-addr.arpa

you will see PTR records, assuming that you are allowed to do the zone
transfer.
