How do I do a whois domain lookup for free?

Enter the domain name in the field above and run the tool. It queries the domain's official RDAP record through the rdap.org gateway and shows the registrar, registration and expiry dates, name servers, and status — free, no signup, nothing installed.

How can I check a domain registration date?

Run a whois lookup on the domain and read the "Registration date" line — it comes straight from the registry's RDAP record. The same result also shows the expiry date, which tells you when the current registration period ends.

What is the difference between whois and RDAP?

WHOIS is the legacy plain-text protocol (port 43) with inconsistent output per registrar; RDAP (Registration Data Access Protocol) is its modern, standardized JSON-based replacement. This tool uses RDAP via the rdap.org gateway, so results are structured and machine-readable instead of scraped text.

Can I find out who owns a domain with a whois lookup?

Usually not anymore. Most registries redact the registrant's name, email, and address for privacy (GDPR and similar rules), so a lookup typically shows the registrar and technical data rather than the owner's identity. If the data is redacted, it is redacted at the registry — no lookup tool can bypass that.

Why does a whois lookup say domain not found?

A 404 from the RDAP gateway usually means the domain is not registered — or that its TLD is not supported by rdap.org. Double-check the spelling and TLD, then confirm availability with a registrar before treating it as free to register.

Is a free whois lookup accurate?

The data comes from the registry's own RDAP record, so registrar, dates, name servers, and status are as accurate as the registry's data. Cached or recently transferred domains can lag briefly, and privacy-redacted fields simply will not appear.

Whois Lookup

What is Whois lookup?

Whois Lookup — Run a free whois lookup on any domain to see its registrar, registration and expiry dates, name servers, and status — live RDAP data, no signup.

This tool performs a live whois-style lookup using RDAP (Registration Data Access Protocol), the modern replacement for classic WHOIS port-43 queries. Your browser fetches https://rdap.org/domain/<domain> directly — no server of ours is involved — and the response is parsed exactly the way the vendored networktools engine (rezashams991/991-networktools, MIT) does it: registrar from the entity with the "registrar" role (vCard "fn" field, falling back to the handle), dates from the registration/expiration/last-changed events, and name servers from the nameservers array. Limitations: the lookup needs an internet connection and a reachable rdap.org; results depend on what the registry publishes — many registries redact registrant contact details for privacy; some TLDs are unsupported and return "not found"; dates render in your browser locale.

Good to know

The lookup is a live client-side call to rdap.org — it needs an internet connection and a reachable gateway; offline or on gateway downtime the tool reports an error instead of data.
Registrant contact details are usually privacy-redacted by registries; the tool cannot reveal redacted data.
Some TLDs are unsupported by the rdap.org gateway and return "domain not found" even for registered names.
Dates are displayed in the visitor's browser locale, matching the vendored engine's behavior.

Examples

Check a domain before buying it

Status: not found (404) means the name is likely unregistered — but confirm with a registrar before assuming availability.

Audit your own domain

The pasted URL is normalized to myblog.com; the tool shows registrar, expiry date, and name servers for a quick health check.

Verify a client domain handover

Registrar and status lines confirm the domain transferred to the expected registrar and is active.
