WHOIS Lookup

Domain age, registrar, expiry, and nameservers via RDAP — WHOIS's successor.

Updated July 10, 2026

How to use the whois lookup

  1. 1Enter a domain — URLs get cleaned to the bare name.
  2. 2Read the age first; it's the trust signal.
  3. 3Check expiry, registrar, and status flags.
  4. 4Empty result on a ccTLD? That registry may not publish RDAP.

Common uses

  • Five-second scam check on unfamiliar stores
  • Domain age for SEO and due-diligence research
  • Checking when a wanted domain expires
  • Verifying your own domain's lock status and expiry

Frequently asked questions

How do I use domain age to spot scam sites?

Before buying from an unfamiliar store: look it up here. A 'established boutique' whose domain registered three weeks ago is answering your question. Fraud operations churn domains because blocklists catch up — so extreme youth plus deep-discount inventory plus no physical address is the classic triad. Calibration: young isn't proof of fraud (every legitimate site was new once) and old isn't proof of safety (aged domains get bought), but as a five-second prior, registration date is the strongest single signal available.

Why can't I see who owns the domain?

GDPR, mostly: in 2018 registries and registrars redacted personal data from public records worldwide (simpler than geofencing compliance), and privacy-proxy services were already common before that. What survives is still useful — dates, registrar, status, nameservers — and ownership contact happens through the registrar's relay or the site itself. For legal needs (trademark disputes, abuse), registrars maintain the real data and disclose it through proper process; the public record just no longer hands it out.

What do the status codes like clientTransferProhibited mean?

They're EPP status flags, and the scary-sounding ones are usually protective: clientTransferProhibited means the registrar locks transfers unless the owner unlocks — standard anti-hijacking hygiene, present on most healthy domains (clientDeleteProhibited similarly). The genuinely concerning ones: anything with 'hold' (serverHold, clientHold) means the domain is suspended and not resolving; redemptionPeriod/pendingDelete mean it's expiring out and heading back to the open market — which is also how you snipe a domain you want.

The lookup found nothing — is the domain available?

Maybe. A not-found result means no RDAP record via the bootstrap, which usually means unregistered — but some country-code TLDs (.de and others) don't publish RDAP, and rare bootstrap gaps exist, so 'no record' isn't a registration guarantee in either direction for ccTLDs. For .com/.net/.org and most modern gTLDs, not-found is a strong availability signal. Confirm at any registrar's search before celebrating, and if it is available, note that registrars all sell the same product — compare renewal prices, not first-year teasers.

About this tool

The WHOIS lookup shows a domain's registration record — age (the headline number), registration and expiry dates, registrar, status flags, and nameservers — using RDAP, the structured protocol that officially replaced classic WHOIS, queried through the IANA bootstrap. Domain age is the fastest fraud test on the internet: scam stores overwhelmingly run on domains registered weeks ago, and this check takes five seconds. The tool is honest about the protocol's limits: GDPR redacted owner identities from public records in 2018, and some country-code TLDs don't publish RDAP at all.

The whois lookup connects to an external service to fetch live data, so some of what you enter is sent over the network to provide the result — see the note in the tool for specifics. We don't require an account, and we don't store your queries. Most tools on UtilityBase run entirely in your browser; this one needs the network to do its job. Browse more developer tools here.
