The IPFire DBL is published as a Response Policy Zone (RPZ) and can be consumed by many popular recursive DNS resolvers.

Resolvers fetch the list via AXFR/IXFR, store it locally, and only transfer updates when the zone changes — keeping bandwidth usage low and resolution fast.

All IPFire DBL lists are also available as downloadable domain and hosts files.

These formats are intended for setups where the lists are consumed directly, for example by firewalls, filtering proxies, custom tooling, or systems using hosts-file based blocking. The files can be fetched periodically and applied locally.
