	Do each zone in a seperate file if you want seperate zones.

A.B.0.rev:
$TTL <value>
@	SOA ..
	NS ..
$GENERATE 1-254   $ PTR   a$.a.com.

A.B.1.rev:
$TTL <value>
@	SOA ..
	NS ..
$GENERATE 1-254   $ PTR   b$.a.com.

	If you want it to be in one file the the zone need to be
	B.A.IN-ADDR.ARPA.

zone "B.A.IN-ADDR.ARPA" {
	type master;
	file "A.B.rev";
};
