This won't work as you need NS records that match up to the zone name,
In this case, the common zone name is only "in-addr.arpa." but no NS for
that. Also if it was only "in-addr.arpa." the two PTR records would be
useless. If your zone name does match so you have a NS record, as it is
now, you'd have "out-of-zone data" which is ignored. Try using two
different more specific zone files such as for 11.148.132.IN-ADDR.ARPA.
