What is hostmap

hostmap is a free, automatic, hostnames and virtual hosts discovery tool written in Ruby by Alessandro `jekil` Tanasi and licensed under GNU General Public License version 3 (GPLv3). It's goal is to enumerate all hostnames and configured virtual hosts on an IP address. The primary users of hostmap are professionals performing vulnerability assessments and penetration tests.

It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.

- Sun Tzu, The Art of War

As Sun Tzu said, you have to know your enemy. During an hacking engagement, like a penetration test, you need to retrieve as much information as possible from your target in order to be successful.

hostmap helps you using several techniques to enumerate all the hostnames associated with an IP address.

The major features are:

  • DNS names and virtual hosts enumeration
  • Multiple discovery techniques, to read more see documentation.
  • Results correlation, aggregation and normalization
  • Multithreaded and event based engine
  • Platform independent
