Assume that a large number of consecutive IP addresses are available starting at 198.16.32.0 and suppose that two organizations, A, B, C, and D, request 1000, 3000, 2000, and 4500 addresses, respectively, in that order. For each of these, give the first possible IP address within the assigned subnet, the last possible IP address within the assigned subnet, and the subnet representation in slash notation (w.x.y.z/s). In the imagine I have the answers but I am very confused on how to get them. Specially after A and B I do not undertand how the initial address of C is 198.16.64.0 how did that 64 happen??? Please explain all in detail. Thank you!
