WHOIS Lookup
Investigate any domain with our free WHOIS helper — resolve its live DNS in-browser and jump to trusted WHOIS services for registrar and ownership data.
About the WHOIS Lookup
WHOIS records reveal who registered a domain, when, through which registrar, and which nameservers it uses. This tool helps you investigate any domain by resolving its live DNS in your browser and linking you directly to the authoritative WHOIS services that publish the full registration record.
The WHOIS protocol is served over port 43 (and increasingly over registrar-specific RDAP endpoints), neither of which a browser can query directly for security reasons. Instead of returning made-up data, this tool is transparent about that limit: it shows the DNS records we can gather for free and sends you to reputable lookups like ICANN Lookup and who.is for verified registrar, dates and nameserver details.
Use it when vetting a domain to purchase, researching a competitor, chasing down abuse, or confirming your own registration details. The DNS footprint shows where the domain lives now; the linked WHOIS services show its registration history.
How to Use the WHOIS Lookup

- 2Review the live DNS records resolved in your browser.
- 3Open a linked WHOIS service for registrar, dates and nameserver data.
- 4Cross-reference both sources to build a full picture.
Frequently Asked Questions
What information is in a WHOIS record?
A WHOIS record typically lists the registrar, the domain's creation, update and expiry dates, the status codes, and the authoritative nameservers. Historically it also showed the registrant's name and contact details, though these are now often masked by privacy services or redacted under data-protection rules.
Why can't this tool query WHOIS directly?
WHOIS is served over port 43 and RDAP over specific HTTPS endpoints that block cross-origin browser requests. A free, client-side tool cannot reach them without a paid backend, so rather than fabricate data we resolve the domain's DNS and link you to trusted WHOIS services that return the real record.
Why is the registrant hidden behind privacy protection?
Many registrars offer WHOIS privacy that replaces the owner's personal details with a proxy, and GDPR led registries to redact personal data by default. The registrar, dates and nameservers usually remain public even when the individual's identity is protected.
How do I find when a domain expires?
Open a WHOIS lookup such as ICANN Lookup or who.is and read the 'Registry Expiry Date' field. This tells you when the current registration lapses — useful for catching a domain you want or making sure your own does not accidentally drop.
What is the difference between WHOIS and DNS?
WHOIS describes the domain's registration — who owns it and when it was registered — while DNS describes how the domain routes traffic, listing its IP addresses, mail servers and nameservers. This tool shows live DNS directly and links out for the WHOIS registration side.
