Consider the topology shown below with following requirements: Three subnets A, B, C, should have enough addresses to support 250 interfaces, 120 interfaces, and 1000 inter- faces, respectively. The IP addresses for three subnets should be assigned continuously, with spacing of power-2, that means, 250 will be rounded to 256, and so on. For each subnet, the assignment should take the form a.b.c.d/x a) What is the IP address range, lowest and highest address for subnet A? b) What is the IP address range, lowest and highest address for subnet B? c) What is the IP address range, lowest and highest address for subnet C? d) Give valid (3) IP addresses for each router.
