Project Overview: ban-pcdn-ip
The "ban-pcdn-ip" project is dedicated to collecting a comprehensive list of IP addresses associated with Peer-to-Peer Content Delivery Network (PCDN) traffic that maliciously inflates CDN (Content Delivery Network) usage for websites. This issue has emerged as some PCDN owners have redirected their previous BitTorrent (BT) traffic towards CDNs used by websites, leading to unexpectedly high operational costs for many web administrators.
IP List
The project features a file named ipdb.txt, which contains a sorted list of IP address segments known to be used by PCDN entities for undesirable activities.
Script: main.py
A Python script called main.py is part of the project toolkit. This script is used to sort and eliminate duplicate entries in ipdb.txt. If contributors have a Python environment set up on their local machines, they are encouraged to run main.py after adding new IP segments before submitting changes. For those without Python, manually sorting and inserting the addresses in the correct position within the file is an acceptable alternative. Ideally, new address segments should be added in sorted order to minimize the need for post-merge adjustments.
Contributing to the IP Database
The project heavily relies on community contributions to expand the IP database. Contributors are encouraged to directly add new IP segments to ipdb.txt and submit them for review. To prevent incorrect blocking of legitimate IPs, it's important for those submitting pull requests (PRs) or issues to provide evidence of CDN abuse, such as screenshots or a reliable source link, to facilitate verification.
