Enterprise-Grade, Accurate and Real-Time

Firmographic Data

We source all our data from authoritative WHOIS databases, and cross-check each record with RDAP endpoints.

IP addresses (whole blocks of them) are assigned by the IANA, to Regional Internet Registries (RIRs) who then assign them to their members. Each member can then allocate them to their customers.

Large to medium-sized corporations, universities, institutes and governments typically own their own IP blocks. For other organizations, the Internet service providers (ISPs) are responsible for allocating IP addresses.

We provide accurate and up to date data for all these cases.

Trusted IP to Company Data: Transparent Sources and Methods

Open Infrastructure

We share our data aggregation process and data sources openly. We offer a public status page to show the current state of our data.

Use it to debug our data against other providers, your own data or to build your own aggregator. We show low-levels details, down to the network requests and database operations.

We do this to set a higher standard for data quality, and to make it easier for you to understand where our data comes from.
