Your boss wants you to add one subnet to an existing design. The existing design already has five subnets: 10.0.0.0 /24 10.0.1.0 /25 10.0.2.0 /26 10.0.3.0 /27 10.0.6.0 /28 The boss cannot decide among five competing subnet masks to use for this next new subnet to add to the internetwork. However, the boss wants you to practice VLSM and plan the subnet ID that he would use for each of those four possible masks. He tells you that the new subnet ID must be part of Class A network 10.0.0.0, that the new subnet must not overlap with the original five subnets, and that the new subnet ID must be the numerically lowest possible subnet ID (without breaking the other rules). Pick the one subnet ID that you would plan to use based on each of the following mask choices by the boss: /24, /23, /22, /25
