Efficient Address Allocation with VLSM

Explain how Variable Length Subnet Masking (VLSM) minimizes address waste compared to a fixed-size scheme.

Given a set of host requirements, determine the optimal CIDR prefix for each network segment.

Develop a VLSM allocation plan by ordering segments from largest to smallest and assigning non-overlapping subnets from a parent block.

Document the VLSM plan, including network address, prefix, usable range, and broadcast address for each subnet.

Calculate address utilization efficiency for a given VLSM plan.

Plan subnets for point-to-point links using /30 or /31 prefixes.
