Your employer is opening a new location, and the IT director has assigned you the task of calculating subnets for the new network. 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?

 

2

After the subnetting is complete, how many unused subnets will be waiting on hold for future expansion? How many possible hosts can each subnet support?

3

What is the new subnet mask?

5

What is the CIDR block for this network?

6

What is the broadcast address of the subnet for the host at 172.20.6.139?

7

 

Is the host at 172.20.11.250 on the same subnet as the host at 172.20.12.3? How do you know?
