Network scanner for Internet-wide network studies
ZMap is a fast network scanner designed for Internet-wide network surveys. On
a typical desktop computer with a gigabit Ethernet connection, ZMap is capable
scanning the entire public IPv4 address space in under 45 minutes,approaching
the theoretical limit of gigabit Ethernet. ZMap can be used to study protocol
adoption over time, monitor service availability, and help us better understand
large systems distributed across the Internet. While ZMap is a powerful tool for
researchers, please keep in mind that by running ZMap, you are potentially scanning
the ENTIRE IPv4 address space and some users may not appreciate your scanning.
While previous network tools have been designed to scan small network segments,
ZMap is specifically architected to scan the entire address space. It is built
in a modular manner in order to allow incorporation with other network survey
tools. ZMap operates on GNU/Linux and supports TCP SYN and ICMP echo request
scanning out of the box.
