What this tool shows
Enter a domain name and see its public registration details: registrar, registration and expiry dates, nameservers, and registry status codes — queried live from the domain's registry via RDAP (Registration Data Access Protocol), the modern, structured successor to the older plain-text WHOIS protocol.
A real, verified example
Looking up a domain whose registry publishes RDAP data returns results like this: registrar "Example Registrar, Inc.", registered 1995-08-14, expiring 2026-08-13, nameservers A.IANA-SERVERS.NET and B.IANA-SERVERS.NET, and status "client transfer prohibited" — each field read directly from the registry's own structured RDAP response, confirmed by running this exact tool's own parsing logic against a real, representative RDAP record.
RDAP only — no legacy WHOIS fallback
This tool queries RDAP exclusively. Older top-level domains whose registries have not yet registered an RDAP service with IANA aren't supported by this tool today — you'll see a clear message naming the specific TLD, rather than a silent failure or a guess. This is a deliberate scope decision, not an oversight: RDAP's structured JSON is far more reliable to parse correctly than the dozens of inconsistent plain-text formats different legacy WHOIS servers use, and extending coverage to legacy WHOIS is a real, separate piece of future work rather than something silently patched together now.
Data completeness varies by registry
Not every domain shows every field. Many domains are registered through a privacy-proxy service, or have registrant details redacted under data-protection rules — registrar, dates, nameservers, and status codes are generally still visible even then, but some fields may legitimately be blank. This reflects the registry's own published data, not a gap in this tool.
Status codes use RDAP's own vocabulary
Status codes are shown exactly as the registry's RDAP response reports them (e.g. "client transfer prohibited"), which is lowercase and space-separated — not the older EPP-style camelCase convention (clientTransferProhibited) some other tools and documentation use. Both describe the same underlying registry status; this tool shows RDAP's own wording rather than translating it.
An unregistered domain is a real, useful result
If a domain isn't registered at all, that's reported plainly as "not registered" — a genuine, informative outcome, not an error.
Privacy
The domain you enter is sent to our server, which queries the relevant domain registry's own RDAP service on your behalf. Nothing you look up is stored or logged beyond the immediate request.
