🛡️ DNS Blocking

Automated workflows to fetch, filter, and maintain DNS blocklists for privacy and security. The originaly lists worked but used too much memory. The adjustments below clean up the lists, but I am retaining functionality by adding the TLDs directly to the DNS server.

📋 Overview

This project processes and maintains two DNS blocklists:

• NRD 30-day mini domains-only (source)

  • Filters out domains ending with .ru, .cn, .kp, .zip, .by to reduce memory footprint.
  • The filtered list is saved as lists/nrd-14day-mini-shrink.txt.

• StevenBlack Fakenews-Gambling-Porn-Only hosts (source)

  • Removes comment lines and the 0.0.0.0 prefix.
  • The cleaned list is saved as lists/fakenews-gambling-porn-only-shrink.txt.
