WHOIS Lookup
Lookups go to the public RDAP service and are not stored by this site.
How to use this WHOIS lookup
Using this free WHOIS lookup takes three short steps. First, type a domain name, such as example.com, into the box. You can paste a full address if you like: the tool strips http://, https://, www., and any trailing path or slash before it looks anything up. Second, press Look up, or press Enter. Third, read the live result, which shows the domain, registrar, registration date, last changed date, expiry date, name servers, and status, exactly as returned by the public RDAP service. Lookups go to that public service and are not stored by this site.
Worked example: google.com
The following worked example is clearly labelled as an example, and it describes the kind of result this tool returns. As an example, a live lookup of google.com returns a registrar containing MarkMonitor, with a creation date of 1997-09-15, together with name servers and status entries from the RDAP record. That example shows the age and stability of one of the world’s best-known domains: it was registered in September 1997, long before most people had heard of search engines, and it has been renewed ever since. Try the same lookup yourself above to see the current live record, which may have updated expiry or name server details since this example was written.
What WHOIS and RDAP are
WHOIS is the traditional system for looking up who registered a domain name, when it was registered, when it expires, and which name servers it uses. It grew up with the early internet, and for many years it was a simple text protocol with a different format for every registry. RDAP, the Registration Data Access Protocol, is its modern replacement. RDAP returns structured data in JSON, the same format used by web applications, so tools like this one can read it reliably and display it in a clean, consistent way. This tool uses the public RDAP bootstrap service at rdap.org, which forwards your query to the correct registry’s RDAP server.
Using RDAP rather than an old WHOIS feed matters for accuracy. Because the data is structured, the tool can pick out the registrar, the creation event, and the expiry event by name, rather than guessing from free text. That reduces the risk of misreading a date or confusing a registrar with a reseller. It also means the tool can handle many different registries in the same way, instead of needing a separate parser for each one.
What you can and can’t see
You can see the technical and administrative facts of a registration: the registrar, the dates, the name servers, and the domain’s status, such as whether it is locked against transfer. What you usually cannot see is the personal details of the person who registered it. Since the introduction of GDPR and similar privacy rules, most personal owner details are hidden, or redacted, on modern registrations. You may see an anonymised contact, a privacy service, or simply no personal data at all. That redaction is deliberate: a domain lookup is meant to help you check a domain’s history and technical setup, not to expose someone’s home address or phone number.
Some domains will fail to return a result. That can happen because the domain does not exist, because its registry does not yet support RDAP, or because the RDAP service did not respond in time. When that happens, this tool says so in plain words, and never invents sample data to fill the gap. A failed lookup is not evidence that a domain is free or taken; if you need certainty, check the ICANN Lookup service or the registry for that top-level domain.
Frequently asked questions
What is a WHOIS lookup?
A WHOIS lookup is a search of the public registration record for a domain name. It shows who the registrar is, when the domain was registered, when it expires, and which name servers it points to, so you can check a domain’s history and ownership.
What is RDAP?
RDAP, the Registration Data Access Protocol, is the modern replacement for the old WHOIS protocol. It returns registration data as structured JSON, which makes it easier for tools to read accurately and display consistently across different registries.
Why is the owner’s personal information hidden?
Since GDPR and similar privacy rules came into force, most personal owner details are redacted from public registration records. This protects registrants’ privacy while still allowing the technical facts of a registration, such as dates and name servers, to be checked.
Why do some domains fail to return a result?
A lookup can fail if the domain does not exist, if its registry does not support RDAP, or if the RDAP service does not respond. The tool reports a failure in plain words and never shows fake data as if it were a real result.
Is a WHOIS lookup free and legal?
Yes. Looking up public registration data is free and legal. The data shown here is already public by design, and this tool only displays the registration facts returned by the public RDAP service.
