You are a network planner tasked with developing an IP structure for the following networks. The IP space is to be assigned sequentially from the lowest to the highest address. The largest subnet is to be assigned first then followed in turn by the next largest subnet until they are all assigned. The answers are to be put into the appropriate boxes in the table. You have the address space $14\mathrm{.}126\mathrm{.}112\mathrm{.}0/20.$ The networks are listed below:

Network A: $102$

Network B: $265$

Network C: $3$

Network D: $392$

Network E: $627$

Range of unused addresses:

Complete the table above and explain the results for each subnet in an Excel Spreadsheet.
