The most logical approach to use when managing an address space is to assign ranges of host addresses in a sequential fashion. This approach is sometimes referred to as a right-to-left bitwise approach, because you assign blocks from the lowest end of the address range first (using the rightmost bits) and progress in sequence to the higher numbers (moving toward the leftmost bits) in the address space.
Strengths and Weaknesses
There are many benefits to using this simple approach to address assignment. It's eminently logical and easy to follow. Those are important attributes if you inherit someone else's hostmaster responsibilities, or if you hope to someday pass the torch to someone else. Perhaps the greatest benefit of ...
