Masscan
An Internet-scale TCP port scanner that can scan the entire Internet in under 5 minutes using asynchronous SYN packets.
What is Masscan?
MASSCAN is a high-performance, asynchronous TCP port scanner built for scanning massive IP ranges at extreme speeds. It uses its own custom TCP/IP stack to send SYN packets asynchronously, capable of scanning the entire Internet in under 5 minutes. The tool solves the need for rapid, large-scale network reconnaissance, particularly for security researchers and network administrators mapping open ports across vast address spaces.
Network security professionals, penetration testers, and researchers who need to perform fast, wide-ranging port scans across entire subnets or the global Internet. It's also suitable for organizations conducting large-scale network inventory or vulnerability assessments.
Developers choose MASSCAN for its unparalleled speed and scalability in port scanning, leveraging asynchronous I/O and kernel-bypass techniques to achieve millions of packets per second. Its nmap-compatible interface lowers the learning curve, while features like built-in banner grabbing, IPv6 support, and PF_RING integration make it a robust tool for Internet-scale scanning tasks.
