Case Project 2-1
The key to easily solving this problem comes from assuming that each building will have its own single subnet.
That means that the number of bits in the subnet mask needs to cover at least six addressable subnets. Thus, you
Case Project 2-2
Where expense is a concern, reducing the size of the IP address block that must be leased monthly can matter a lot.

minimum.)
Case Project 2-3
Many corporate IT administrators still manage their IP addresses using an Excel spreadsheet, so this might be a
