Our domain lookup tool queries the same production-grade DNS filtering service that powers our enterprise deployments. Here is what happens when you submit a domain.
You enter a fully qualified domain name. Our system normalizes it, strips protocols and paths, and prepares the query for our distributed lookup infrastructure.
The normalized domain is matched against our 90 million domain index using a high-performance hash lookup. This step completes in under one millisecond on average.
Simultaneously, the domain is cross-referenced against our content classification engine, geographic databases, and hosting infrastructure analysis.
The complete classification profile is assembled and returned: primary category, additional categories, country of origin, and content filtering metadata.
Whether you are investigating a suspicious domain during an incident or auditing your allow-list, our lookup tool gives you the intelligence you need in seconds.
Every lookup queries our complete production database, covering active domains, newly registered domains, and historical entries going back over a decade.
Our globally distributed infrastructure ensures that lookups complete in under five milliseconds, regardless of your location or the volume of concurrent queries.
content risk data is continuously updated from over 40 commercial and open-source feeds. When a domain is newly flagged as malicious, results reflect it within minutes.
See when a domain was first observed, its category change history, and its reputation trajectory over time. Essential context for incident investigation workflows.
The same lookup capability is available via our REST API. Integrate domain intelligence directly into your SIEM, SOAR, ticketing system, or custom tooling.
