These are the main signals used by this tool. Availability can vary by address, domain, registry and data source.
Registration events, status values and nameservers
Public organizations, notices and allocation links when available
Beginner steps
- Enter a domain name without https:// or enter a public IP address.
- Review the authoritative RDAP status, dates, nameservers and organizations.
- Open the permanent report to copy or share a stable URL.
Understand the limits
Registration data describes a domain or network allocation. Contact details may be redacted, and registration does not prove who operates the website or currently uses an IP address.
WHOIS and RDAP lookup explained
Use this tool to check registration and allocation data for a domain name or public IP address. Results come from RDAP, the modern HTTPS-based successor to traditional WHOIS, and can include the authority, status, important events, nameservers and public organizations.
Permanent WHOIS result pages
After a successful lookup, open the permanent page to copy or share a stable address such as /whois/example.com. Missing and temporary-error results remain excluded from search engines.
Privacy and accuracy
Personal contact details are often redacted. Registration data describes a domain or network allocation and should not be treated as proof of a person’s identity, website operator or physical location.

WHOIS / RDAP FAQ for beginners
Is RDAP different from WHOIS?
RDAP is the modern HTTPS and JSON-based registration protocol. It provides structured responses, standard status codes and clearer referral handling.
Why is the owner name hidden?
Registries and registrars often redact personal contact details for privacy. Redaction does not mean a domain is unregistered.
Does WHOIS show website hosting?
Not necessarily. Domain registration, DNS hosting and website hosting can be provided by different companies.
Why can dates differ between tools?
Services may cache at different times or label registry events differently. The authoritative RDAP response is the primary source here.
Can I search an IP address as well as a domain?
Yes. Domain RDAP is handled by the relevant registry, while IP RDAP is handled by the regional internet registry responsible for the address block.
Why does a domain show privacy or proxy contact details?
Many registrars replace personal contact information with a privacy service while still keeping the registration valid and reachable through controlled channels.
