Newer versions of BIND have some functionality for handling just such
an instance.  From the BIND documentation:

	$ORIGIN 0.0.192.IN-ADDR.ARPA.
	$GENERATE 1-2 0 NS SERVER$.EXAMPLE.
	$GENERATE 1-127 $ CNAME $.0

	is equivalent to 

	0.0.0.192.IN-ADDR.ARPA NS SERVER1.EXAMPLE.
	0.0.0.192.IN-ADDR.ARPA NS SERVER2.EXAMPLE.
	1.0.0.192.IN-ADDR.ARPA CNAME 1.0.0.0.192.IN-ADDR.ARPA
	2.0.0.192.IN-ADDR.ARPA CNAME 2.0.0.0.192.IN-ADDR.ARPA
	...
	127.0.0.192.IN-ADDR.ARPA CNAME 127.0.0.0.192.IN-ADDR.ARPA
