Whois / RDAP Lookup

Free, no signup. Registry data, without old WHOIS parsing: registrar, dates, nameservers, domain locks, and clear privacy-redaction context.

Built by Patrick Stox

Checks run from our server; we fetch the URL you enter and don't keep the results. This queries IANA's RDAP bootstrap and the relevant registry. Results may be cached for up to 24 hours; registry privacy policies can redact contacts. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.

Sample report
Illustrative example — documentation-domain fixture
example.com
  • Created: 1995-08-14
  • Registrar: published by registry response
  • Registrant: redacted by registry privacy policy
  • Nameservers: observed RDAP values
  • Status: clientTransferProhibited — transfer is locked at the registrar
Dates and parties in a real report are displayed only when the registry publishes them; missing values remain “Not published.”
 
 
How to use it
  1. Enter a root domain and choose Look up domain.
  2. Review registry dates and registrar separately from registrant contact data.
  3. Read each EPP status explanation and confirm actionable locks in the registrar account.
  4. Use the DNS handoff when nameserver publication needs a resolver-level check.
 
     
 Local data 
Saved targets, named lists, and recent check summaries remain only in this browser.
 
   
 
     
How to read the result
Registration dates are normalized registry events. Parties are registry-published roles and may be redacted. Nameservers are RDAP registration data, not a live DNS resolution test. Statuses are EPP codes with plain explanations, not independent diagnoses.
Data sources & freshness
The endpoint normalizes the domain, follows IANA’s RDAP bootstrap to the responsible registry service, and returns structured events, entities, nameservers, and statuses. The browser formats dates, calculates days to published expiry, and explains supported EPP status codes. Responses may be cached for 24 hours.
Features
  • Structured registrar, date, nameserver, and status fields.
  • Privacy-redaction context instead of blank-owner assumptions.
  • Plain-language EPP status explanations.
  • Prefilled handoff to DNS Checker.
Limitations
Some ccTLDs lack complete RDAP service, registries redact data, and published dates or parties can be absent. The tool does not bypass privacy, guarantee deletion timing, manage renewals, or replace the registrar account. Cached dataCaching stores a copy of a page or resource — in a browser, a CDN edge node, or a search crawler's own cache — so it can be served again without regenerating or re-downloading it. It isn't a direct ranking factor, but it feeds page speed and crawl efficiency. may lag a recent change.
 
Frequently asked questions
Why is registrant information missing?
Many registries redact registrant data under privacy policy or GDPR. Missing data is not proof the domain has no registrant.
Is this WHOIS?
It provides the same practical lookup information via RDAP, the structured successor to traditional WHOIS. Some ccTLD registries do not yet publish RDAP data.
What do clientTransferProhibited and other domain statuses mean?
They are EPP status codes published by the registry. The report explains common locks and holds, but your registrar is the authority for why a status is set and how to change it.
Is the expiry date a guarantee that the domain will be deleted then?
No. Expiry, grace, redemption, auction, and deletion policies vary by registrar and registry. Treat the published date as an operational reminder and confirm renewal in the registrar account.

Common issues & how to fix them
 
     
  •  Error Domain has serverHold status Fix: Contact the registrar or registry to resolve the serverHold cause before expecting DNS publication to resume. 
  •  Error Domain has clientHold status Fix: Resolve the registrar’s clientHold condition, then confirm the status clears and authoritative DNS answers return. 
  •  Error Domain is in redemption period Fix: Request domain restoration through the registrar and pay any redemption fee before the redemption period ends. 
  •  Error Domain is pending deletion Fix: Confirm whether restoration is still possible; otherwise monitor the registry drop because ordinary renewal is no longer available. 
  •  Warning Domain registration expires soon Fix: Renew the domain now, enable auto-renew with valid payment details, and verify the updated RDAP expiration date. 
  •  Information Registration identity is redacted Fix: Use authenticated registrar records for ownership verification because public RDAP redaction is normal and cannot be repaired on the website. 
  •  Information DNSSEC is not indicated Fix: Enable DNSSEC at the DNS provider, publish the DS record through the registrar, and verify the chain of trust.
