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.

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.
NOTE: Marks are given for the correct answers AS WELL AS for the
workings/calculations. Illustrate in detail how you obtain the answers.
(a)
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.
