WHOIS Lookup
Query domain registration details, registrar, and expiry date
Usage
• Domain: enter a bare domain without https:// (e.g. example.com)
• Shows registrar, registration date, expiry date, and NS records
• WHOIS data for some TLDs may be limited
What WHOIS lookup is for
WHOIS lookup queries the authoritative registration database for a domain and returns the registrar name, creation date, expiry date, and name servers. This data comes from the global registry chain — TLD registry records for the domain itself, then registrar records for detailed contact fields.
Common uses include checking when a domain was registered and when it expires, identifying the registrar to initiate a transfer, verifying that name servers are configured correctly, and confirming that a recently registered domain has propagated to the registry.
Frequently asked questions
Why is some WHOIS data hidden or redacted?
Since GDPR and similar regulations, most registrars redact personal contact details by default or proxy them through a privacy service. Registrar name, creation date, expiry date, and name servers are usually still available.
Can an expired domain still be renewed?
Renewal, redemption and release rules depend on the registry, registrar and domain status. A WHOIS date does not guarantee renewal remains available; check the registrar’s current status and deadlines.
How can I verify a name-server change?
WHOIS/RDAP registration data, DNS delegation and resolver caches are different sources. Check registrar settings, parent-zone NS delegation and recursive answers separately rather than assuming all nodes update after a fixed wait.
What is the difference between the registry and registrar?
The registry operates the TLD (e.g. Verisign for .com) and holds authoritative records. The registrar is the company where the domain owner registered the domain. WHOIS data comes from both layers.
