Tutorial 2 - Network Layer (Part3)

Exercise 05
We have the IP address 140.25.0.0/16. 
To achieve this division into subnetworks, the first work consists of dividing the initial network prefix into 8 subnetworks of the same size. 
number 14 of the last subset is itself divided into 8 subnetworks.
We study the deployment of the subnets with variable lenght subnet mask (VLSM) principle.
Here is the sub-network division plan. 



Among these 8 subnetworks, network number 1 is again divided into 32 subnetworks and network number 6 into 16 subnetworks.  
1.       What is the list of addresses of the 8 subnetworks resulting from the first level division?
2.       What is the usable address range for subnet number 3?
3.       What is the list of addresses of the 16 subnets obtained from subnet number 6?
4.       What is the usable address range for subnet number 6 - 3?
5.       What is the broadcast address for subnet number 6 - 5?
6.       What is the usable address range for subnet number 6 - 14 - 2?
7.       What is the broadcast address for subnet number 6 - 14 - 5? 

Exercise 06
We have the IP address 172.16.0.0/16. We study the deployment of the subnets with variable lenght subnet mask (VLSM) principle. 

- Give an addressing plan for this set of subnetworks using VLSM.
