Provides an easy way to check if an IP or a CIDR is blacklisted.
Why was this tool born? I maintain a very big pool of IP addresses, so I needed a way to check if some of the have been blacklisted or not.
Installation is also very easy, if you have debian you can install the application easily by executing the commands bellow
echo "deb http://packages.matoski.com/ debian main" | sudo tee /etc/apt/sources.list.d/packages-matoski-com.list
curl -s http://packages.matoski.com/keyring.gpg | sudo apt-key add -
sudo apt-get update
sudo apt-get install blacklist-checker
