Domain WHOIS Lookup

Check WHOIS registry information, registration dates, registrar, nameservers, and domain status details instantly.

How to Use the Domain WHOIS Lookup Tool

Enter any domain name (for example, google.com or dwellixtools.com) into the search box above and click Lookup WHOIS. Results are fetched in seconds and include:

  • Registrar — The company where the domain is registered (e.g. Namecheap, GoDaddy, Cloudflare).
  • Created, Updated & Expires Dates — When the domain was first registered, last modified, and when it will expire.
  • Domain Status — EPP (Extensible Provisioning Protocol) status codes that indicate whether a domain can be transferred, deleted, or modified.
  • Nameservers — The DNS servers responsible for resolving the domain to an IP address.
  • Raw RDAP Data — The complete technical registry payload for advanced inspection.

What Is WHOIS?

WHOIS is a standard internet protocol used to query databases that store registration information about domain names. Traditionally, WHOIS data was retrieved over TCP port 43 as raw, unstructured plain text — making it difficult to parse reliably.

The modern replacement is RDAP (Registration Data Access Protocol), an HTTP-based API standardized by ICANN and defined in RFC 9083. RDAP returns structured JSON responses, supports internationalized domain names, and provides more granular access controls.

This tool queries the public RDAP.org bootstrap service, which redirects each lookup to the authoritative registry (e.g., Verisign for .com, DENIC for .de). No API key is required.

Understanding Domain Status Codes

Status Code Meaning
active The domain is operational and resolving normally.
clientTransferProhibited Transfer to another registrar is locked (most common; protects against hijacking).
clientDeleteProhibited Domain cannot be deleted by the registrant until this lock is removed.
clientUpdateProhibited WHOIS/registry data cannot be changed without unlocking.
pendingRenew A renewal request is pending at the registry.
pendingTransfer The domain is mid-transfer to a new registrar (takes up to 7 days).
addPeriod The domain was registered within the last 5 days (registry grace period).
autoRenewPeriod The registration lapsed but is in the 30-45 day auto-renew grace window.
redemptionPeriod The domain has expired and entered a recoverable redemption state (30 days).
pendingDelete The domain is scheduled for deletion and will soon return to open availability.

Privacy and API Transparency

This tool sends your domain query request directly from DwellixTools servers to the authoritative RDAP registry at the moment you click Lookup. The following data handling rules apply:

  • DwellixTools does not log, store, or track which domains you look up.
  • Only publicly available registry data is returned — personal registrant contact details are redacted by modern gTLD registries under ICANN’s Temporary Specification for GDPR Compliance.
  • Queries are processed on Cloudflare’s edge network and discarded immediately after the response is delivered.

Common Use Cases

  • Domain Buyers: Check whether a domain is registered before attempting to purchase or contact the owner.
  • IT Administrators: Verify expiry dates and nameserver configurations for domains you manage.
  • Security Researchers: Investigate newly-registered domains or check ownership details for phishing investigations.
  • Developers: Test that your domain transfer or nameserver change was processed by the registry.
  • Webmasters: Check how long until your domain expires to avoid accidental lapses.
