If APNIC gave you only a single class C, yes.
The bottow line is: you need to follow the APNIC rules. If they assigned a
class C to you is because their current rules for that class C range is to
assign on a /24 manner. Most likely they have other blocks of class C that
they assign on CIDR mode.
Does it help?

It means that if you got an allocation from arin of say a /24, /23,
etc. That its the least likely space to be routable. Back in the
day,
ARIN would allocate a /24 to just about anyone on the net with a
presense......this space is not part of any provider aggregate, and
its
the least likely to be routable.
