In this episode you will learn: - VLSM (Variable-Length Subnet Masking) allows using different subnet masks in the same network to conserve IP addresses. - The most critical rule for VLSM planning on the CCNA exam is to always allocate IP blocks from the largest host requirement to the smallest. - Common exam traps include starting with the smallest subnet, miscalculating block boundaries, and creating overlapping address ranges. - To find the correct subnet size, calculate the required host bits (2^n - 2 >= hosts) and use that to determine the CIDR mask. - A helpful mnemonic for VLSM planning is: "Large to Small, or You'll Waste it All."
