UT1 Toulouse → NextDNS Blocklists

This repository automatically converts UT1 (Université Toulouse 1 Capitole) blacklist categories into NextDNS-compatible blocklists.

Contents

• update_lists.py: downloads the UT1 archive, cleans domain entries, and generates dist/*.txt plus ut1<id> metadata.
• dist/UT1-<group>.txt: grouped blocklists generated from multiple categories (large ones are automatically split into ...-1.txt, ...-2.txt, etc.).
• ut1<id>.json (example: ut1adult.json): NextDNS-compatible metadata file generated per published list.

Requirements

• Python 3.10+
• Python dependencies: requests, PyYAML

Quick installation:

python -m pip install requests pyyaml

Local Usage

1. Edit the existing .env file (already committed in the repo). It is written in YAML and serves as the canonical template for defining bundles and GitHub metadata. Adjust the sections to match the categories you want to publish—no separate example is required.

• bundles describes every published list (comma-separated strings or true YAML lists are both supported). At least one entry is required.
• Per-category files are always generated for every available UT1 category.
• When a bundle exceeds ~70 MB, it is automatically split into multiple UT1-<group>-N.txt files. The corresponding ut1<id>.json entries follow the "UT1 bundle " naming convention and list every part so you can add them all in NextDNS.

2. Run:

python update_lists.py

Automation

The GitHub Actions workflow (.github/workflows/update.yml) runs every day, then automatically commits and pushes updated files.
