Problem # 3 (6 points): Consider a router that interconnects 3 subnets: Subnet 1, Subnet 2. and Subnet 3. Suppose all of the interfaces in each of these 3 subnets are required to have the prefix 224.1.18/24. Also suppose that Subnet 1 is required to support 60 interfaces, Subnet 2 is to support interfaces, and Subnet 3 is to support 91 interfaces. Provide three network addresses of the form a.b.c.d/x that satisfy these constraints
