Despite the capital letters in “WHOIS”, it is not an acronym. Yet as the name suggests, a WHOIS record tells you all about a domain name’s registrant. Each WHOIS record gives pertinent details about the domain, including its age, registration status (creation, last update, and expiration dates), registrar, and owner. It allows users to obtain a domain owner’s contact details for reasons that include cyber investigation, market research, domain purchase, competitor monitoring, and more.
Our WHOIS database contains more than a billion records spanning domains and subdomains scattered across 7,298+ gTLDs, ccTLDs and ccSLDs.
We parse and normalize all of our WHOIS data so it can be used as is or quickly integrated into a variety of internal systems.
We provide query results in convenient formats across all of our products. API outputs are available in XML and JSON, database downloads in CSV and MySQL, and lookup reports are hosted using a custom URL and are shareable.
