Domain intelligence

Investigate a company domain through DNS, registration, certificates, and subdomains.

Start with a domain

Enter a company domain in Domain Tool to collect technical context that can help validate a business, understand its web footprint, or prepare a website review.

Use the evidence carefully

Domain records can reveal related hostnames, but they do not prove company ownership or an active commercial relationship. Confirm important conclusions with additional sources.
