Huh?

There is no need to make the figure a power of 2.

If the company request 200 IDs, the one-layer-up entity can delegate
exactly 200 IDs.
Or, if the the one-layer-up entity think 200/256 large enough (I think
this is the case), it can delegate 256 IDs.

No.
Read the following sentense, again and again.
