NMAP Ping Commands

If you have been following the NMAP articles I have written then you may have noticed something important about the scans. NMAP prefers to perform a Ping. A Ping to NMAP is a test to verify that the system to be scanned is really on-line and exists. If NMAP is to scan multiple systems on a subnet, or a whole subnet, then it will first test which systems are available to scan.
