KALI – MASSCAN – Faster than NMAP

19/12/2015

This is the fastest Internet port scanner. It can scan the entire Internet in under 6 minutes, transmitting 10 million packets per second.

Masscan scans a port at a time, whereas NMAP scans a host at a time.  It reports a port at a time, rather than combining all results for the host.  Its Asynchronous so is a 1,000 times faster.

In conclusion, to scan a couple of hosts use NMAP.

To scan thousands of ports use Masscan.

The two tools are complementary.
