NOTES:
* To find the Submask in VLSM, use the S = Num. ^ Num., I.e S = 2 ^ 4 = 128 + 64 + 32 + 16 = 240
* VLAN , IP Address is always in the last valid host range
* For the first hop, for Building 1, get the serial address of Building 2
* The IP address (Fa) for the router of the IP address is the 'default gateway' of the switch.
