OISD Big is a Ad/Tracking Blocklists threat-intelligence feed, refreshed daily, indexed by WhisperGraph.

What is OISD Big

OISD Big is the larger of the two main tiers published by the OISD project, a DNS blocklist aggregator that combines dozens of upstream ad, tracker, malware, and phishing lists into a small number of curated tiers rather than requiring users to manage many individual subscriptions. The Big tier extends the project's default "Small" tier with broader tracker and telemetry coverage, at a correspondingly higher (though still curated and de-duplicated) chance of an occasional false positive. OISD has become one of the more widely recommended DNS blocklists in the Pi-hole and AdGuard Home communities due to its active maintenance and de-duplication process. It is indexed here as a widely-deployed aggregated DNS blocklist tier.
