Domain registration records—collectively known as WHOIS data—store ownership, contact, creation, and expiry details that help administrators keep the global Domain Name System running smoothly. Registries publish these records so that network operators, legal teams, and security analysts can audit provenance or resolve disputes.
This tool retrieves a domain’s WHOIS dataset through a privacy-respecting client-side request, parses the reply, and presents key fields plus the complete JSON for further analysis. By executing entirely in your browser, it avoids server storage while still delivering authoritative information seconds after you submit a query.
Use it to confirm renewal deadlines before transferring a site, verify that nameservers match your hosting plan, or investigate unexpected status flags when email delivery fails. Cross-check sensitive domains regularly to avoid unplanned downtime.
WHOIS is a distributed query protocol, standardised by RFC 3912, that returns plain-text records describing a domain’s registrar, registrant, status codes, and lifecycle dates. Registrars publish these records to registry servers; queries propagate through thin or thick models until the authoritative source responds. Typical variables include domain name, record status, and expiry date.
| Field | Meaning |
|---|---|
| Registrar | Accredited organisation managing the registration |
| Status | Lifecycle codes such as ok, clientTransferProhibited |
| Created | Date the domain was first registered |
| Updated | Last modification date recorded by the registry |
| Expires | Scheduled expiry; renew before this date to avoid deletion |
| Nameservers | Authoritative DNS hosts for the zone |
“OK” status signifies a domain in good standing. Transfer-prohibited codes block registrar moves until the lock is cleared. Missing nameservers prevent resolution, producing NXDOMAIN errors.
example.org.Example (example.com)
Request → example.com · Response shows Registrar = IANA-reserved, Created = 1995-08-14, Expires = 2025-08-13, Status = ok. Nameservers list the authoritative root zone hosts.
Protocol behaviour aligns with RFC 3912 and ICANN Registrar Accreditation Agreement sections on data escrow and publication. Lifecycle terminology follows ICANN EPP status code definitions.
The lookup transmits only the domain string; no personal data is processed, aligning with GDPR recital 26 on non-personal information.
The workflow requires just one input and completes in under five seconds for most domains.
example.com.No. Queries execute entirely inside your browser and are not logged or retained by the tool.
Registries vary in disclosure policies; certain country-code domains redact information or omit optional sections.
WHOIS operates at the registered domain level; sub-domain ownership follows its parent and is not individually recorded.
This status indicates the registrar has locked the domain against transfers; disable the lock before moving to another provider.
Check business-critical domains monthly and whenever DNS changes are planned to avoid surprises at renewal time.
