An Internet Service Provider (ISP) is granted a block of addresses starting with 150.80.0.0/22. The ISP needs to have 4 subblocks of addresses to use in its four subnets: one subblock of 200 addresses, one subblock of 330 addresses, one subblock of 100 addresses, and one subblock of 62 addresses. With the available information, a) Calculate the number of addresses in the block and determine the address mask, first address, and last address of the block. b) Determine the number of allocated addresses, subnet mask (n), address mask, first address, and last address for each of the subblocks. c) Calculate the number of unused addresses and provide its first address and last address.
