Assume that a large number of consecutive IP addresses are available starting at 198.16.0.0 and suppose that two organizations, A and B, request 4000 and 2000 addresses, respectively, in that order. For each of these, give the first IP address assigned, the last IP address assigned, and the mask in slash notation (w.x.y.z/s). Convert the IP address whose hexadecimal address 0 times D31EC251 to dotted decimal notation. Your answer must be exact. Use the format 255. 255. 255. 255 and DO NOT enter any spaces
