Package masscan

https://github.com/robertdavidgraham/masscan

This is an Internet-scale port scanner. It can scan the entire
Internet in under 6 minutes, transmitting 10 million packets
per second, from a single machine.
It is a faster port scan that produces results similar to nmap,
the most famous port scanner. Internally, it operates more like
scanrand, unicornscan, and ZMap, using asynchronous transmission.
