WHOIS Domain Lookup

Look up a domain's registration record — who it's registered with, when it was created, when it expires, its status codes and name servers — right in your browser. The tool queries RDAP (Registration Data Access Protocol), the structured, JSON-based successor to the old text-based WHOIS protocol, directly from your browser.

How to use it

Type a domain name (e.g. example.com) and click Look up. The result shows the registrar, important dates with a plain-English "days until expiry" note, name server list, DNSSEC status, and every EPP status code with a short explanation of what it means. A Show raw RDAP response toggle reveals the full underlying JSON if you need it — for scripting, debugging, or checking a field the summary doesn't surface.

What is RDAP, and how is it different from WHOIS?

RDAP is the modern replacement for WHOIS, standardized by IETF and adopted by ICANN-accredited registries. Where classic WHOIS returns loosely-formatted plain text that differs by registry, RDAP returns consistent, structured JSON — which is what makes a reliable summary like this one possible. Functionally they answer the same question ("who owns this domain, and what's its status"), so this tool effectively replaces a whois command for most registries.

Why don't I see the registrant's name or address?

Since GDPR and similar privacy regulations took effect, almost all registrars redact personal registrant details (name, email, address) from public RDAP/WHOIS records by default. When a registrant organization is present and not redacted, it's shown; when it isn't public, the field is simply omitted rather than shown as "N/A" for every domain.

What do the status codes mean?

EPP status codes (like clientTransferProhibited or ok) describe restrictions the registrar or registry has placed on the domain — for example, whether it can be transferred, renewed, or deleted right now. Each code in the result is paired with a plain-English explanation.

Is my lookup private?

The lookup goes directly from your browser to rdap.org, which redirects it on to whichever registry is authoritative for that domain's extension (Verisign for .com, for example) — it isn't routed through or logged by our servers. Only the domain you look up is sent, and only rdap.org's and that registry's own terms and rate limits apply.

What if I need DNS records instead of registration details?

WHOIS/RDAP data tells you who owns a domain and its registration status, not how it resolves. For actual DNS records (A, MX, TXT, NS and more), use the DNS Lookup tool. To inspect a site's SSL/TLS certificate rather than its domain registration, use the SSL Certificate Decoder. To look up your own or another IP address's geolocation, see IP Lookup.
