Extracted text: An organization is given a block of addresses and one of the addresses in the block is 8.16.32.64/27. You need to create four variable length subnets: one subnet of 60 addresses, one subnet of 30 addresses, and one subnet of 12 addresses and one subnet of 12 addresses. Design the subnets by finding the subnet mask, the first address and the last address for each subnet. Also identify the range of addresses left unused.
