4. Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24. Also suppose that Subnet 1 is required to support at least 90 interfaces, Subnet 2 is to support at least 50 interfaces, and Subnet 3 is to support at least 10 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints and complete range of addresses for three subnets. (6)

5.Suppose a sender using the CRC generator 1001 needs to send the bits 11010111010. What bits are actually transmitted? Show your work. (5)
