FAQ

What is an IP to company lookup?

An IP to company lookup maps an IP address to the organisation that operates it. IP Trust returns the company's legal name, a classification (ISP, business, hosting, government, or education), the company's website domain, and a short description of what they do. This powers use cases like B2B lead enrichment, audience analytics, and access control.

What data does the IP to company API return?

The IP to company API returns four fields for each IP address: the company name, the organisation type (one of ISP, business, hosting, government, or education), the company's primary domain, and a human-readable description of their products or services. All fields are available on Plus and Premium plans.

How does IP Trust map an IP address to a company?

IP Trust derives company data from public RIR (Regional Internet Registry) records, WHOIS data, and reverse DNS lookups. These sources are cross-referenced and cleaned to produce accurate organisation names and metadata. The dataset is updated daily to reflect ownership changes, new IP allocations, and corporate restructuring.

Can I download the IP to company database for local use?

Yes. IP to company data is included in the Hosting & Company database package, available for download in MMDB, CSV, JSON, and Parquet formats. Once downloaded, you can run IP to company lookups entirely on your own infrastructure with zero external API calls and unlimited query volume. See our database downloads page for details.

How accurate is IP to company data?

IP to company accuracy depends on how IP address space is allocated. Large organisations that own their own IP ranges are identified with high confidence. Smaller companies using shared ISP or cloud hosting address space may not be individually identifiable. IP Trust combines multiple data sources - RIR records, WHOIS, and reverse DNS - and updates daily to maximise coverage and accuracy.
