WHOIS Domain Lookup
Queries a public record from our server — not your files.
Look up a domain's registration: the registrar, when it was created, when it expires, the EPP status codes with what each one means, and the nameservers it is delegated to. It queries RDAP rather than port-43 WHOIS — the same data in a structured form that every gTLD registry has been required to publish since 2019, instead of free text that varies by registry. The domain you enter goes to our server, which asks the registry directly. It is a public record, and it is the only thing sent.
This tool is an exception on this site. Everything else here runs entirely in your browser, but a web page cannot query DNS, read a certificate or see another site’s response headers — so the name or URL you enter is sent to our server, which looks up the public record and sends the answer back. The answer is cached for up to a minute. No file of yours is read, uploaded or stored, and there is no account.
How to use WHOIS Lookup
- 1
Enter the domain name — the registrable one, so example.com rather than www.example.com.
- 2
Read the expiry date and the status codes; a "hold" status means the domain is out of DNS regardless of its records.
- 3
Check the nameservers match the DNS provider you think you are using.

Frequently asked questions
Does this send my data anywhere?+
It sends the domain name to our server, which queries the authoritative registry for that TLD over RDAP and caches the answer briefly. Registration data is a public record maintained by the registry. Nothing from your device is uploaded, and no account is involved.
Why is the owner's name and email missing?+
Because it is redacted, not absent. Since GDPR took effect in 2018, registries and registrars withhold the personal details of private registrants and publish a forwarding contact instead. Every WHOIS tool shows the same gap — one claiming otherwise for an ordinary domain is showing you stale data.
What is the difference between RDAP and WHOIS?+
WHOIS is a 1980s plain-text protocol on TCP port 43 with no defined format, so parsing it means a pile of per-registry guesses. RDAP is its ICANN-mandated replacement: the same registration data, as JSON, over HTTPS, with the same field names everywhere. The name "WHOIS" survives because it is what people call the job.
What do clientTransferProhibited and the other statuses mean?+
They are EPP status codes, and the report explains each one it finds. The "client" prefix means your registrar set it — a transfer lock, which you want on. The "server" prefix means the registry did, which usually indicates a dispute or an abuse case. Any "hold" status removes the domain from DNS entirely, whatever its records say.
It found nothing for my domain.+
Most likely its registry does not publish RDAP. Every gTLD does, but a number of country-code registries — some of them large — still run WHOIS only, or restrict lookups to their own website. The tool says so rather than reporting the domain as unregistered.
