Announcement: Partial support of Legacy Subdomains and Hosts Lists - Migration to a new repository

Effective August 1, 2026, blocklists in domains and hosts formats that require explicit subdomain enumeration will no longer be fully supported.

Affected Software

This mainly affects software that still depends on these legacy formats, including:

• Pi-hole (only older versions with an FTL version lower than v5.22); starting with FTL v5.22, the AdBlock/ABP format is supported.
• Blocky older than v0.23
• Diversion older than v5
• PersonalBlocklist
• pfBlockerNG
• AdAway
• uMatrix
• OpenSnitch
• DNS66
• NetGuard
• Hostfile (Windows/Linux)
• Other tools using subdomain-based domains or hosts lists

Timeline

• Links to these formats will be removed from the README during this week.
• The lists will continue to be updated via the existing URLs until August 1, 2026.
• From August 1, 2026, GitHub RAW/jsDelivr cached links will no longer work.
• After this date, the host and subdomain formats will only be available in the following repository: https://github.com/hagezi/dns-blocklists-legacy
• The lists will be updated daily.

Reason

These formats are inefficient, incomplete by design, require large lists, increase maintenance effort, and are no longer considered modern or practical for reliable subdomain blocking.

Please migrate to a supported modern format before August 1, 2026.

If migration is not possible, the formats will remain available in the following repository. The lists are updated daily:

Thank you for your understanding,
Gerd
