current text in the "Command" field, and replace it with your own command$),$ and specify all networks in the organization as the target. You can specify multiple networks by adding commaseparated numerical values in the appropriate octet to account for all networks.

Use the Internet to discover the nmap option that performs OS fingerprinting as part of the scan. Once you have determined the correct command, run it to take inventory of the operating system on each host in the organization. This process will take about $5$ minutes.

Hint: The resulting command will have the following format, where coptions is a letter that corresponds to the OS fingerprinting method, and where $A,B,C,$ and D correspond to the first, second, third, and fourth octet values: nmap $-$ coptions $A,B,B,B,B,B,B.C.\frac{D}{24}$

In your Network Assessment spreadsheet, open the Asset Inventory tab and, in a new column, document the OS nmap was able th discover for each host. If an OS was not discovered for a host, place a question mark beside it to indicate further exploration is required $($or$,$ if you're inclined, access that machine and determine the os for yourself$).$

Make a screen capture showing the completed Asset Inventory tab with the new OS column.
