See who registered a domain — registrar, dates, nameservers, status.
WHOIS is the public registry protocol for domain names. When a domain is registered, details like the owner's organization, registrar, creation date, expiry date, nameservers, and status codes are recorded in a publicly accessible database.
WHOIS lookups are used for checking domain availability, verifying registration dates, identifying the managing registrar, and investigating suspicious websites. Security researchers rely on WHOIS data to trace malicious infrastructure and protect brands.
Note that GDPR and similar privacy laws have led many registrars to redact personal details from public WHOIS output. This tool retrieves all available registration data for any domain.
Enter the domain in the WHOIS lookup above and click Lookup. You get registrar, creation and expiry dates, nameservers, and status codes when the registry publishes them. Personal owner names are often redacted (GDPR).
WHOIS is a public database of domain registration details — registrar, creation and expiry dates, nameservers, and status codes. Use it to verify ownership timelines or investigate suspicious domains.
Privacy laws like GDPR led many registrars to redact personal contact details. Registration dates, registrar, and nameservers are usually still visible.
Yes. Enter any domain and get available registration data instantly with no account required.
WHOIS is the registration database for domain names. A lookup returns registrar name, creation and expiry dates, nameserver assignments, domain status codes (clientTransferProhibited, etc.), DNSSEC flags, and abuse contact information when published. This data helps verify ownership timelines, investigate suspicious domains, and plan renewals before expiry.
Creation Date — domains registered days ago carrying financial or login branding are high-risk for phishing. Registry Expiry Date — missing renewal causes the domain to enter redemption; set calendar reminders 60 days ahead. Name Server — should match your DNS host (Cloudflare, Route53, etc.); unexpected NS entries may indicate hijacking. Domain Status — clientHold or serverHold means the domain will not resolve. DNSSEC — unsigned is normal for small sites; signed adds integrity protection when configured correctly.
A finance team received an invoice from acme-paymerts.com (typo domain). WHOIS showed the domain was registered three days prior with privacy protection and nameservers at a bulletproof host — strong indicators of invoice fraud rather than a legitimate vendor.
WHOIS accuracy depends on registrant updates. Some TLDs use different WHOIS servers with varying field formats. We return publicly available data only — not legal ownership proof. For trademark disputes, use official registrar dispute processes.
