Zmap

Zmap is an open-source network scanner designed for performing fast, large-scale internet-wide scans. It uses a novel approach that sends packets in a stateless manner, allowing it to scan the entire IPv4 address space in under 45 minutes. This makes it particularly useful for security research, network monitoring, and census studies of internet-connected devices.

Also known as: ZMap, zmap, Z-map, ZMap Scanner, Internet Scanner

Why learn Zmap?

Developers should learn Zmap when they need to conduct rapid, comprehensive scans of the internet for security assessments, vulnerability research, or academic studies. It is ideal for tasks like identifying open ports, detecting vulnerable services, or mapping network topologies across large IP ranges, where traditional scanners like Nmap are too slow.
