In this chapter, you subnetted a Class C private network into six subnets. In this project, you work with a Class B private network. Complete the steps as follows:
- Your employer is opening a new location, and the IT director has assigned you the task of calculating the subnet numbers for the new LAN. You’ve determined that you need 50 subnets for the Class B network beginning with the network ID 172.20.0.0. How many host bits will you need to use for network information in the new subnets?
- After the subnetting is complete, how many unused subnets will be waiting on hold for future expansion, and how many possible hosts can each subnet contain?
- What is the new subnet mask?
- Complete the following table:
Subnet number Extended network prefix Range of host addresses Broadcast address 1 172.20.0.0 172.20.0.1 through 172.20.3.254 2 172.20.4.0 through 172.20.7.254 3 172.20.8.1 through 172.20.11.255 4 5 … … … … 50 - What is the CIDR notation for this network?
- What is the broadcast address of the subnet for the host at 172.20.6.139?
- Is the host at 172.20.11.250 on the same subnet as the host at 172.20.12.3? How do you know?
