WHOIS Lookup
Enter any domain name and instantly retrieve its registration details using the RDAP (Registration Data Access Protocol) standard, which is the modern replacement for traditional WHOIS. The tool shows the registrar, creation date, expiration date, last updated date, nameservers, and domain status codes.
RDAP responses come from the authoritative registry for each top-level domain, routed through rdap.org. This means you get official registration data without needing to parse unstructured WHOIS text.
Useful for checking domain availability context, verifying ownership details, confirming expiration dates, or investigating nameserver configuration. All queries go directly from your browser to the RDAP endpoint — nothing is logged or stored by this tool.

Frequently asked questions
What is RDAP and how does it differ from WHOIS?▼
RDAP (Registration Data Access Protocol) is the modern, standardized replacement for the legacy WHOIS protocol. It returns structured JSON instead of free-form text, supports HTTPS, and is maintained by ICANN. The data content is essentially the same as WHOIS.
Why are some registration details hidden?▼
Many domain registrars offer privacy protection (also called WHOIS privacy or domain privacy) that replaces the registrant's personal information with the registrar's proxy details. This is a feature of the registration, not a limitation of the tool.
Does it work for all domain extensions?▼
It works for most common TLDs (.com, .net, .org, country codes, and many new gTLDs) that have RDAP servers registered with IANA. Some older or less common extensions may not yet support RDAP.
Is this tool free?▼
Yes. RDAP is a free, open protocol and rdap.org is a free routing service. No API key or account is required. Queries go directly from your browser.
