I always use the range for several reasons, mostly related to ease of
management. I like to give my zone files the same names as the zones
they represent, and names with / in them require subdirectories. The /
can also require special handling in scripts. Finally the range makes it
very clear exactly what IP addresses are intended to be part of the zone
which cuts down on errors in the parent /24 zone file (especially when
you correctly specify the range, which you did not do above). :)
