WHOIS Lookup

Query WHOIS registration information for any domain name.

Enter a domain name without http:// prefix

Enter a domain and click Lookup to retrieve its registration details.

Runs entirely in your browser via RDAP — the modern, CORS-enabled successor to WHOIS.

What this WHOIS lookup tool does

WHOIS is the public registration record behind every domain name. When someone registers a domain, the registrar records details such as when it was created, when it expires, which registrar manages it, the authoritative name servers, and the current status of the domain. This tool retrieves that record for any domain you enter and displays the raw response so you can read it in full.

It is useful for checking whether a domain is available or already taken, finding out when a registration is due to expire, identifying which registrar holds a domain, confirming name server configuration, and doing basic due diligence before buying or partnering around a domain name.

How to use it

Type a domain name into the input box without the http:// prefix, for example example.com, then press Lookup or hit Enter. The tool queries the domain's registry and shows a readable summary of the key fields, followed by the complete raw response, in a scrollable panel. A Copy button lets you grab the entire record to paste elsewhere.

The lookup runs entirely in your browser using RDAP (the Registration Data Access Protocol), the modern HTTP and JSON-based successor to classic WHOIS. Because RDAP is served over standard web requests with CORS enabled, no server of our own is involved — your query goes directly from your browser to the authoritative registry, just like the DNS and IP lookup tools.

Reading and interpreting the results

Look for the creation, updated, and expiry dates to understand a domain's age and renewal timeline, and check the registrar line to see who manages it. The status codes (such as clientTransferProhibited) describe locks and restrictions placed on the domain, while the name server entries confirm where DNS is hosted.

Be aware that many registrars now redact personal contact details to comply with privacy regulations like GDPR, so owner names and emails are often replaced with privacy-protection placeholders. Some country-code domains also limit how much information they publish, which means the level of detail can vary widely from one extension to another.

Frequently Asked Questions

What information does a WHOIS lookup return?▼
It typically shows the registrar, creation and expiry dates, last-updated date, domain status codes, and the authoritative name servers. Contact details may be redacted for privacy.
Does this run in my browser or on a server?▼
Entirely in your browser. It uses RDAP, the modern HTTP/JSON successor to WHOIS, which is served with CORS enabled — so your query goes straight from your browser to the domain's registry with no server of ours in between.
Which domains are supported?▼
Most common gTLDs such as .com, .net, .org, .io and .dev support RDAP and work well. A small number of country-code TLDs do not yet publish RDAP data, in which case the lookup will report that no record was found.
Why are the owner's name and email hidden?▼
Most registrars redact personal contact data to comply with privacy laws such as GDPR, replacing it with privacy-protection placeholders. This is normal and not an error.
Can I check if a domain is available to register?▼
Yes. If a domain has no WHOIS record or returns a 'no match' style response, it is likely unregistered and may be available, though you should confirm with a registrar.
Is the tool free to use?▼
Yes, it is free and requires no account. Enter a domain and click Lookup as often as you need.
