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 60 interfaces, Subnet 2 is to support at least 90 interfaces, and
Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of
the form a.b.c.d/x) that satisfy these constraints.
