The IPFire team has spent years protecting networks at the edge — we understand threats, filtering, and what it takes to keep systems secure. Combined with our community's expertise, we are building a blocklist that is not just comprehensive, but extremely accurate through continuous refinement and real-world feedback.
What sets DBL apart is how we deliver it. Beyond traditional filtering methods, we have implemented DNS Response Policy Zones (RPZ) with IXFR for lightning-fast incremental updates — your resolver only downloads what has changed. We provide Suricata rulesets for deep packet inspection across DNS, TLS, HTTP, and QUIC — catching threats that bypass simple domain matching. And we support standard formats like domain lists and hosts files for maximum compatibility.
This is our contribution to the open-source security community: a blocklist built by firewall experts, maintained by practitioners, and engineered for the real world. Transparent, collaborative, and designed to evolve with every threat we face together.
Category-Based Filtering
Block entire categories of domains including malware, phishing, adult content, social media, gambling, and more. Exercise granular control over what content reaches your network.
Deep Packet Inspection
Integrates with Suricata IDS/IPS to analyze DNS, TLS, HTTP, and QUIC traffic. Blocks malicious domains at multiple network layers for comprehensive protection.
Open & Community-Driven
Built and maintained by the IPFire community with full transparency and a commitment to long-term sustainability. Continuously updated with emerging threats, completely open-source, and welcoming community contributions — you are in control of your security.
Works Everywhere
Built directly into IPFire's Web Proxy and Intrusion Prevention System. Also designed to work with other firewall and filtering solutions. Open standards mean you can use IPFire DBL wherever you need domain-based protection.
