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, subnet-1 is required to support upto 125 interfaces and subnet-2 and 3 are each required to support upto 60 interfaces
Write a feasible set of subnet address / subnet mask pairs?
