Case 1: Create an Addressing Scheme.
Step 1: Use the 147.144.0.0/16 address to create an addressing scheme to accommodate all hosts on the network. Begin the address assignments with the 147.144.64.0 address. Start with the largest subnet and assign address blocks in decreasing order of size, without skipping any addresses.
Document all subnet addresses in Table 1.
