Masscan

AGPL-3.0

馃寪 Network ReconC

Masscan is the fastest Internet port scanner. It can scan the entire Internet in under 6 minutes, transmitting 10 million packets per second from a single machine. It produces results similar to Nmap but operates asynchronously, transmitting packets without waiting for responses. The internal architecture is more similar to scanrand and unicornscan than traditional scanners. It uses a custom TCP/IP stack to avoid the overhead of the operating system's networking stack.
