Masscan vs ZMap
GitHub Stats
About Masscan
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.
About ZMap
ZMap is a high-speed network scanner designed to perform internet-wide scans using single packets. Capable of scanning the entire IPv4 address space in under five minutes, it is ideal for large-scale network research. Written in C, ZMap is used by researchers and security professionals to uncover open ports and services across vast network segments. Its efficiency and scale make it a vital tool for comprehensive network analysis.
