Is This IP Bad? is a python script that will check an IP against popular IP and DNS blacklists.
python3 isthisipbad.py
I don't know what I am doing.
Update: I wrote this code over six years ago as a side project and had not given it much thought. Since people were still using it, it had some errors and bad lists, so I updated it to Python3 and removed offline or bad sources.
