Pinger is a tool for doing really fast ping sweeps.
It's nothing special really, pinger just calls ping on the local machine in a subprocess for each host in the subnet via a multiprocessing pool.
Python >= 3.4
pip3 install --user https://github.com/bobthebutcher/pinger/archive/master.zip
You may need to restart your shell to update your path
