How do i use nmap to scan hosts on a network segment?



  • Nmap can use a number of methods to scan for hosts.

    The option used is:

    -sn: Ping Scan - disable port scan
    

    The description says Ping Scan, here Ping means nmaps various ping methods, some are dependent on if the privileges available. For more on this see the nmap documentation: https://nmap.org/book/man-host-discovery.html

    $ nmap -sn <target>
    

    Where the target can be a CIDR address.
