Problem B: You have been given the 192.168.40.0/24 network address to subnet, with the following topology. Step 1: Determine the number of subnets in Network Topology A. 2) How many subnets are there? Remember: - All LANs connected to Routers are to be counted as a subnet - Router1 (R1) to Router2 (R2) is to be counted as a subnet. - Router2 (R2) to Router3 (R3) is to be counted as a subnet. - Router3 (R3) to Router4 (R4) is to be counted as a subnet. 3) How many bits should you borrow to create the required number of subnets? 4) How many usable host addresses per subnet are in this addressing scheme? 5) What is the new subnet mask in dotted decimal format? Page 3 of 4 IST 220 Data Communications Name IPv4 Address Subnetting - \#3 6) What is the new CIDR notation for each new subnet? (original network = /24) 7) What is the increment between subnets? 8) How many subnets are available for future use? step 2: Record the subnet information. Fill in the following table with the subnet information
