You are given the IP address block 172.16.224.0 with the subnet mask 255.255.240.0 and told to design a system that supports at least 14 subnets (You may end up supporting more subnets but each subnet must support as many hosts as possible while not violating this constraint). All subnets are expected to be of equal capacity in terms of number of hosts supported (in other words, no VLSM). Note that your last subnet may not be the 14th one.

• How many assignable hosts can each subnet support? [A]
• What is the new subnet mask in dotted-decimal notation? [B]
• What is the first assignable host address on the first subnet? [C]
• What is the broadcast address for this first subnet? [D]
• What is the last assignable host address on the last subnet? [E]

(Enter all the IP address and subnet mask answers in dotted-decimal notation in the spaces provided.)

You are given the IP address block 192.168.112.0 / 20 and told to use this network to build subnets (as many as possible) that will support at least 120 hosts per subnet.All subnets are expected to be of equal capacity in terms of number of hosts supported (in other words, no VLSM).

• What is the subnet mask in dotted-decimal notation that you need to use to meet this requirement? [F]
• How many subnets will this produce? [G]
• What is the network address for the last subnet? [H]

(Enter all answers in dotted-decimal format in the space provided.)
