A company owns the network 192.168.0.0/24 and needs subnets for three departments: Department A requires at least 50 hosts, Department B at least 20 hosts, and Department C at least 10 hosts. Using variable‑length subnet masking (VLSM) and allocating the largest subnet first, assign a subnet to each department, give the network and broadcast addresses for each, and state the remaining unused address block.
