ZMap: The Internet Scanner
ZMap is a fast single packet 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. With a 10gigE connection and PF_RING, ZMap can scan the IPv4 address space in under 5 minutes.
ZMap operates on GNU/Linux, macOS, and BSD. ZMap currently has full implemented probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a large number of UDP probes. If you are looking to do more involved scans, e.g., banner grab or TLS handshake, take a look at ZGrab, ZMap's sister project that performs application-layer handshakes.
The latest stable release of ZMap is version 2.1.1 and supports Linux, macOS, and BSD. It can be installed through the built-in package managers on the following operating systems:
|Debian or Ubuntu||
|Fedora, CentOS, and RHEL||
|macOS (using Homebrew)||
Instructions on building ZMap from source can be found in INSTALL.
A guide to using ZMap is found in our GitHub Wiki.
We added IPv6 support to ZMap and include the following new probe modules:
- ICMPv6 Echo Request:
- IPv6 TCP SYN (any port):
- IPV6 UDP (any port and payload):
You can specify the respective IPv6 probe module using the
--probe-module command line flag.
In addition, you need to specify the source IPv6 address with the
--ipv6-source-ip flag and a file containing IPv6 targets using the
More information can be found using the
As targets for your IPv6 measurements you can e.g. use addresses from our IPv6 Hitlist Service.
