Project description

Build Status Documentation Status Codacy Badge Join the chat at Gitter Follow on Twitter


Logo IVRE (Instrument de veille sur les réseaux extérieurs) or DRUNK (Dynamic Recon of UNKnown networks) is a network recon framework, including tools for passive recon (flow analytics relying on Zeek, Argus, Nfdump, and active recon (IVRE uses Nmap to run scans; IVRE can also import XML output from Nmap and Masscan), and JSON output from ZGrab2 and ZDNS.

The advertising slogans are:

  • (in French): IVRE, il scanne Internet.
  • (in English): Know the networks, get DRUNK!

The names IVRE and DRUNK have been chosen as a tribute to "Le Taullier".


You can have a look at the project homepage, the screenshot gallery, and the quick video introduction for an overview of the Web interface.

We have a demonstration instance, just contact us to get an access.

A few blog posts have been written to show some features of IVRE.


IVRE's documentation is hosted by Read The Docs, based on files from the doc/ directory of the repository.

On an IVRE web server, the doc/* files are available, rendered, under /doc/.

On a system with IVRE installed, you can use a --help option with most IVRE CLI tools, and help(ivre.module) with most IVRE Python sub-modules.

Have a look at the FAQ!

Feel free to contact the author and offer him a beer if you need help!

If you don't like beer, a good scotch or any other good alcoholic beverage will do (it is the author's unalienable right to decide whether a beverage is good or not).


Code contributions (pull-requests) are of course welcome!

The project needs scan results and capture files that can be provided as examples. If you can contribute some samples, or if you want to contribute some samples and would need some help to do so, or if you can provide a server to run scans, please contact the author.


For both support and contribution, the repository on Github should be used: feel free to create a new issue or a pull request!

You can also join the Gitter conversation (that is the preferred way to get in touch for questions), or use the e-mail dev on the domain
