Sure. Let's say the subnet is 192.168.0/24. You might have zone data files that look something like this:
db.abc.com:
@ IN SOA ...
IN NS ...
foo IN A 192.168.0.1
db.def.com:
@ IN SOA ...
IN NS ...
bar IN A 192.168.0.2
db.ghi.com:
@ IN SOA ...
IN NS ...
baz IN A 192.168.0.3
db.192.168.0:
@ IN SOA ...
IN NS ...
1 IN PTR foo.abc.com.
2 IN PTR bar.def.com.
3 IN PTR baz.ghi.com.
