WHOIS is now RDAP
Since 28 January 2025, RDAP has replaced WHOIS as the official source of registration data for generic domains such as .com, .net and .org. This tool uses RDAP, so the data comes straight from the registry.
What you won’t see
Owner names, emails and addresses are usually hidden for privacy. To contact an owner, use the registrar’s contact form, or report abuse through the registrar abuse contact shown.
Some country domains, such as .pk, don’t offer RDAP yet. For those, check the country registry’s own website.
How the check works
Your browser sends the address to our server, which makes the request and sends back the result. We don’t keep the addresses you check. To stop misuse, each visitor can run about 20 checks a minute.
Frequently asked questions
How do I find a domain's owner?
Most details are private. You can ask through the registrar, or use ICANN’s request system for legitimate reasons.
Why is the expiry date useful?
An expiring domain may soon be up for renewal, or for sale if it lapses.
Is the lookup stored?
Results are cached for a few hours to keep the registries’ load down. Your search isn’t linked to you.
