Question

Figure 1 shows two Administrative Systems (AS) assigned with the network 202.2.176.0/21 and 200.2.96.0/21 respectively. Using variable-length subnet masking (VLSM), create the necessary subnets for the areas shown in Figure 1 (assume IP subnet-zero). Ensure that you always utilize the next available network in your IP plan.

 

1) Calculate the network address, and subnet masks for all the subnets (Area 1 to Area 7). Hint: The number of usable addresses in Area 4 corresponds to the number of gateway interfaces.
