What is MASSCAN?

MASSCAN produces results similar to Nmap icon Nmap , the most famous port scanner. Internally, it operates more like scanrand, unicornscan, and ZMap, using asynchronous transmission. The major difference is that it's faster than these other scanners. In addition, it's more flexible, allowing arbitrary address ranges and port ranges.

NOTE: masscan uses a custom TCP/IP stack. Anything other than simple port scans will cause conflict with the local TCP/IP stack. This means you need to either use the -S option to use a separate IP address, or configure your operating system to firewall the ports that masscan uses.
