EXERCISE 2 (7.5 points) - The network depicted in the figure below uses addresses from the address space 131.175.0.0/16. a) Divide the address range in at least 5 blocks with maximum host size. How long is the network portion of the addresses? Write the network portion of the first 5 blocks. (1.5 points) b) Use the first of the 5 blocks obtained at point a) to attribute addresses to the subnets connected to router E. Each of these subnets must contain 62 hosts PLUS the router. Which is the maximum number of subnets you can obtain? How long is their network prefix? (1.5 points) c) Write the network address, the range of addressable hosts and the broadcast address of the last subnet obtained at point b)? (1 point) d) Use the second of the 5 blocks computed ad point a) to attribute addresses to the 7 subnets connected to router F. Which is the maximum number of hosts that each subnet can contain? How long is their network prefix? Enumerate the network addresses of the 7 subnets. ( 2 points) e) The third block obtained at point a) is divided in 4 subnets. The first subnet is assigned to eth2, the other 3 are assigned to the subnets connected to router G. How long is the network prefix of these 4 subnets? List their network addresses. ( 1.5 points)
