Black Hole Zone Generator

A really simple set of tools to automate the generation of black hole Bind zones for known malicious hosts.

DNS black holing is a simple and effective way of preventing malicious traffic on your network. Usually this is done by maintaining a list of entries in your systems hosts file but you can easily protect a whole network in a single place by offloading the responsibility to a single Bind server.

Installation

All that's needed is to run the included install script:

./install.sh

Usage

The blackhole lists are created & updated by running the following:

./run.sh

This repo comes with a predefined set of host sources in sources.csv. This could easily be expanded with additional sources to suit your needs.
