For the variable-size subnetting, show (1) the sizes of the subnets and (2) the IP-address ranges for each subnet. d. Network 205.10.10.0/24 into the variable length subnets: Net-A, Net-B, Net-C, such that: Net-A supports 100 hosts, Net-B supports 55 hosts, and Net-C supports 16 hosts, at least. e. Network 170.5.23.0/21 into the variable length subnets: Net-A, Net-B, Net-C, such that: Net-A supports 480 hosts, Net-B supports 75 hosts, and Net-C supports 800 hosts, at least. f. Divide the network 150.50.125.0/21 into the variable length subnets: Net-A, Net-B, Net- C, and Net-D, such that: Net-A supports 200 hosts, Net-B supports 600 hosts, and Net-C supports 200 hosts, and Net-D supports 100 hosts, at least.
