masscan
is a network scanning tool that uses a similar approach to discover the available systems that Nmap uses. However, to finish its network scan quickly, Masscan is quite aggressive with the rate of packets it generates.
The syntax is quite similar: -p
can be followed by a port number, list, or range:
masscan MACHINE_IP/24 -p443
masscan MACHINE_IP/24 -p80,443
masscan MACHINE_IP/24 -p22-25
masscan MACHINE_IP/24 ‐‐top-ports 100
