WHOIS / RDAP Lookup
Domain WHOIS and RDAP lookup — registrar, expiry date, status codes, name servers, and registrant fields when published.
About this tool
Look up live domain registration data before renewals, acquisitions, or DNS migrations. The report summarizes registrar, dates, status, and name servers, with full RDAP or classic WHOIS text when you need to audit details.
What you get
- Registrar, created date, expiration date, and registry status codes
- Delegated name servers for DNS hosting verification
- Registrant and admin contact fields when the TLD registry publishes them
- Full RDAP JSON or WHOIS text in a collapsible block
- Cached permalink with Recheck for a fresh lookup
How to use
Enter a domain like example.com and click Lookup. Only check domains you are authorized to investigate.

FAQ
How to look up domain WHOIS registration online?
Enter a domain name and run lookup. The report shows registrar, created and expiry dates, status codes, name servers, and registrant fields when the registry publishes them.
How to find when a domain expires?
Check the expiration or registry expiry date in the summary before renewals, acquisitions, or monitoring competitor domains.
What is the difference between WHOIS and RDAP?
Both reveal registration data. This tool queries live RDAP servers first and falls back to classic port-43 WHOIS when needed for full coverage.
How to see name servers in a WHOIS lookup?
Delegated name servers are listed in the results so you can confirm DNS hosting after a transfer or migration.
Can I check domain owner and registrar details?
Registrar name, registration dates, and public registrant contact fields appear when the TLD registry discloses them—many gTLDs now redact personal data.
Does WHOIS show if a domain is available?
An unregistered name typically returns not-found or available status; registered domains show active dates and registrar instead.
