3. (15 points) An organization is granted the block 130.56.0.0/16. The administrator wants to create 1024 subnets. Assume no IP address is reserved for special tasks. a. What is (are) the subnetmask (s)? b. What is the IP address of the first host in subnet 1? Show your answer in decimal IP notation. c. What is the IP address of the last host in subnet 2? Show your answer in decimal IP notation. Note: Hosts and subnets start from 0. So in this problem, e.g., a "fifth host" is actually "host 4". 4. (10 points) Assume a company that wishes to partition its organization into a maximum of 8 individual departments (with no possibility of increasing the departments in future) and each department having 10. a. What is the network mask for the company? Show the mask in decimal IP notation. b. What is the subnetwork mask or each company department? Show the subnet mask in decimal IP notation. 5. (6 points) Combine the following three blocks of addresses into a single block: a) 16.27.24.0/26, b) 16.27.24.64/26, c) 16.27.24.128/25. For the final block show the network address and the mask. 3.
