Ping Only Scan
The -sP option is used to perform a simple ping of the specified host.
Usage syntax: nmap -sP [target]
Output of a ping only scan
This option is useful when you want to perform a quick search of the target network
to see which hosts are online without actually scanning the target(s) for open ports.
In the above example, all 254 addresses in the 192.168.10.0 subnet are pinged and
results from live hosts are displayed.
When scanning a local network, you can execute Nmap with root privileges for
additional ping functionality. When doing this, the -sP option will perform an ARP ping and return the MAC addresses of the discovered system(s).
Usage syntax: nmap -sP [target]
Output of a ping only scan (as root)
