Published Outputs

Ready-to-use blocklist files are published daily to the output branch:

  • Domain and IP blocklists/allowlists compatible with Pi-hole, pfBlockerNG, AdGuard Home
  • Lists organized by size (mini, lite, normal, big) and category (ads, malware, privacy)
  • Top entries based on source frequency for high-confidence blocking

⚡ Quick Usage: Add https://raw.githubusercontent.com/phani-kb/dns-toolkit/output/[filename] to your DNS filtering tool (Pi-hole, AdGuard Home, pfBlockerNG).

Most commonly used outputs; Click any link to open the file.

Category Files (click to open)
🗂️ Consolidated 🛑 Blocklists: adguard · cidr_ipv4 · domain · ipv4 · ipv6
Allowlists: adguard (allowlist) · domain (allowlist) · ipv4 (allowlist)
📏 Mini — low false positives 🟢 mini_adguard, mini_cidr_ipv4, mini_domain, mini_ipv4
📏 Lite — balanced protection 🟡 lite_adguard, lite_cidr_ipv4, lite_domain, lite_ipv4
📏 Normal — broader protection 🔵 normal_adguard, normal_cidr_ipv4, normal_domain, normal_ipv4
📏 Big — aggressive coverage 🔴 big_adguard, big_cidr_ipv4, big_domain, big_ipv4, big_ipv6
⭐ Top lists — min3 to min12 top_adguard_min3, top_adguard_min5 · top_domain_min3, top_domain_min5 · top_ipv4_min3, top_ipv4_min5 (min3 means "at least 3 sources", min5 means "at least 5 sources", etc.; higher minN → higher confidence, fewer entries.)

View Detailed Overlap Analysis Comprehensive analysis showing how entries are shared across different DNS sources.

Conflicts Report (allowlist vs. blocklist) A daily-generated report listing entries found in both allowlists and blocklists, including the source(s) where they were found.

Processing summaries and metadata are archived in the summaries branch with 1-year retention.

Quick add (copy-ready URLs)

Copy one of these raw URLs directly into your DNS filtering tool.

Pi-hole (domain lists)

https://raw.githubusercontent.com/phani-kb/dns-toolkit/output/domain_blocklist.txt

AdGuard Home (AdGuard format)

https://raw.githubusercontent.com/phani-kb/dns-toolkit/output/adguard_blocklist.txt

pfBlockerNG (pfSense)

Use the 'DNSBL' > 'DNSBL Groups' section and add a custom list using the raw URL. Example domain list (paste into pfBlockerNG custom list):

Source Configuration (Important!)

Sources are configured in data/config/sources*.json files. Each source specifies:

  • Download URL and frequency
  • Source type (domain, IPv4, IPv6, AdGuard, etc.)
  • Categories (ads, malware, privacy, etc.)
  • License and website information

Special Note on Top Domains (tranco-list.eu)

Top domains sourced from the tranco-list.eu list (domain_top type) are treated as an allowlist.
