Consider a router that interconnects three subnets: subnet1, subnet2, 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 60 interfaces, subnet2 is to suppoprt at least 90 interfaces, and subnet 3 is to support at least 12 interfaces. provide three network address ranges (of the form a. b.c. d/x) that satisfy these constraints.
