well, someone must create them, because that's how DNS works. you can of
course redirect them to one zone but that may cause useless troubles
- if you made error in _any_ of two zones through lookups will go, the
lookups may fail.

Therefore it's better to create separate zones for /24, unless you have /16
(or /8) and want to put all into one file (well, one mistake can make whole
file and all records unreachable).

This descries classless DNS for subnets smaller than /24.
For wider than /24 it's mostly useless.
