MASSCAN is an Internet-scale port scanner. It can scan the entire Internet in under 5 minutes, transmitting 10 million packets per second, from a single machine. It uses its own ad hoc TCP/IP stack.
It uses asynchronous transmission, similar to port scanners like scanrand, unicornscan, and ZMap. It’s more flexible, allowing arbitrary port and address ranges.
Its usage (parameters, output) is similar to nmap, the most famous port scanner. When in doubt, try one of those features — features that support widespread scanning of many machines are supported, while in-depth scanning of single machines aren’t.
This is free and open source software.
