        "Public Interest Registry provides this RDAP service for informational purposes only, and to assist persons in obtaining information about or related to a domain name registration record. Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time. By submitting this query, you agree to abide by this policy."

What is a WHOIS lookup?

WHOIS is the public directory of who holds a domain name or a block of IP addresses. A lookup shows the registrar the domain was bought through, when it was created and when it expires, its name servers, its status codes and an abuse contact for reporting spam or phishing. For IP addresses it shows the network's owner, address range and the regional internet registry (ARIN, RIPE NCC, APNIC, LACNIC or AFRINIC) that allocated it.

RDAP: the modern WHOIS

This tool queries the Registration Data Access Protocol (RDAP), the structured JSON successor to the old text-based WHOIS protocol. We find the authoritative registry server for each TLD or IP range from IANA's bootstrap files, so results come directly from the source. For the few country-code TLDs that do not offer RDAP yet, we fall back to classic port-43 WHOIS.

Why is the owner's name hidden?

Since the EU's GDPR took effect in May 2018, registrars redact personal data of individual registrants by default, and many offer free privacy services that do the same for companies. To contact a domain owner, use the registrar's contact form or the abuse address shown. Read more about WHOIS and privacy.

Understanding domain status codes

StatusMeaning
active / okNormal state with no restrictions.
client transfer prohibitedRegistrar lock against unauthorised transfers. Recommended.
client update / delete prohibitedExtra locks that block changes or deletion.
server hold / client holdThe domain is not published in DNS, often for non-payment or a dispute.
redemption periodExpired and deleted, but the previous owner can still restore it for a fee.
pending deleteWill be released for anyone to register within about five days.

Frequently asked questions

How do I find out when a domain expires?

Enter it above; the expiry date and countdown come straight from the registry.

Is this WHOIS lookup free?

Yes. There is no sign-up and no limit for normal use.

How do I check if a domain is available?

Use the domain availability checker, which tests a name across popular extensions at once.
