Consider Classless Inter Domain Routing (CIDR) is adopted to allocate the IP addresses to three subnets: Subnet A, B, C. Supposed all of the interfaces in each of these three subnets are required to have the prefix 134.161.154.0/23. Also suppose that Subnet A is required to support up to 250 hosts, Subnet B and C are each required to support 120 hosts. Determine the network address allocations for the three subnets in the form a.b.c.d/x to satisfy the constraints. Please show the process
