Question 3) IP Addressing Design In the following network R1 and R2 are routers, and SW1, SW2, SW3 and SW4 are layer-2 Ethernet switches. Building 1 and Building 2 each have 100 PCs, and Building 3 has 50 PCs. The company intends to assign all IP addresses from the range 10.0.100.0/23. Design an IPv4 addressing plan for this company. For each subnet, identify the network address, subnet mask, broadcast address and the total number of host addresses available in that subnet. Building 1 SW1 SW4 R1 R2 SW2 SW3 Building 2 Building 3
