# ZMap: The Internet Scanner  ZMap is a fast stateless single packet network scanner designed for Internet-wide network surveys. On a typical desktop computer with a gigabit Ethernet connection, ZMap is capable of scanning the entire public IPv4 address space on a single port in under 45 minutes. For example, sending a TCP SYN packet to every IPv4 address on port 25 to find potential SMTP servers. With a 10gigE connection and either [netmap](http://info.iet.unipi.it/~luigi/netmap/) or [PF_RING](http://www.ntop.org/products/packet-capture/pf_ring/), ZMap can scan the IPv4 address space in under 5 minutes. ZMap operates on GNU/Linux, Mac OS, and BSD. ZMap has fully implemented probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a large number of [UDP probes](https://github.com/zmap/zmap/blob/master/examples/udp-probes/README). If you are looking to do more involved scans (e.g., banner grab or TLS handshake), take a look at [ZGrab 2](https://github.com/zmap/zgrab2), ZMap's sister project that performs stateful application-layer handshakes. ## Using ZMap ZMap is easy to use. A simple scan of the entire IPv4 space on TCP port 80 can be performed with the following command (requires root privileges): sudo zmap -p 80 $ sudo zmap -p 80 ... 0:00 0%; send: 5 1 p/s (185 p/s avg); recv: 0 0 p/s (0 p/s avg); drops: 0 p/s (0 p/s avg); hitrate: 0.00% 52.8.107.196 ... 0:01 0%; send: 10327 10.3 Kp/s (10.1 Kp/s avg); recv: 118 118 p/s (115 p/s avg); drops: 0 p/s (0 p/s avg); hitrate: 1.14% If you haven't used ZMap before, we have a step-by-step [Getting Started Guide](https://github.com/zmap/zmap/wiki/Getting-Started-Guide) that details how to perform basic scans. Documentation about all of ZMap's options and more advanced functionality can be found in our [Wiki](https://github.com/zmap/zmap/wiki). For best practices, see [Scanning Best Practices](https://github.com/zmap/zmap/wiki/Scanning-Best-Practices). ## Installation The latest stable release of ZMap is [4.4.0](https://github.com/zmap/zmap/releases/tag/v4.4.0) and supports Linux, macOS, and BSD. See [INSTALL](INSTALL.md) for instructions on to install ZMap through a package manager or from source. ## Architecture More information about ZMap's architecture and a comparison with other tools can be found in these research papers: * [ZMap: Fast Internet-Wide Scanning and its Security Applications](https://zmap.io/paper.pdf) * [Zippier ZMap: Internet-Wide Scanning at 10 Gbps](https://jhalderm.com/pub/papers/zmap10gig-woot14.pdf) * [Ten Years of ZMap](https://arxiv.org/pdf/2406.15585) ## Citing ZMap If you use ZMap for published research, please cite the original research paper: @inproceedings{durumeric2013zmap, title={{ZMap}: Fast Internet-wide scanning and its security applications}, author={Durumeric, Zakir and Wustrow, Eric and Halderman, J Alex}, booktitle={22nd USENIX Security Symposium}, year={2013} } ## License and Copyright ZMap Copyright 2024 Regents of the University of Michigan Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
