"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."

}WHOIS / RDAP report for wikipedia.org ============================================================ Source: RDAP (rdap.publicinterestregistry.org) Checked: 2026-10-22 19:34 UTC Registered: Yes Registrar: MarkMonitor Inc. (IANA ID 292) Created: 2001-01-13 00:12 UTC Expires: 2027-01-13 00:12 UTC Last updated: 2026-08-12 08:47 UTC DNSSEC: Unsigned Abuse contact: abusecomplaints@markmonitor.com Status: - clientDeleteProhibited - clientTransferProhibited - clientUpdateProhibited Nameservers: - ns0.wikimedia.org - ns1.wikimedia.org - ns2.wikimedia.org Registrant: Not published by the registry Generated by Seorism WHOIS Lookup — https://seorism.com/tools/whois-lookup
How to use Domain WHOIS Lookup
- Enter a domain such as example.com — you can also paste a full URL or an email address.
- Seorism finds the official registry for the domain’s extension and asks it for the registration record.
- Review the dates, status codes and nameservers, and expand the raw response for the full technical detail.
What it checks
- Registrar and IANA registrar ID
- Registration, expiry and last-updated dates
- Domain status codes, explained in plain language
- Authoritative nameservers
- DNSSEC signing status
- Registrant details, when the registry publishes them
Frequently asked questions
What is the difference between WHOIS and RDAP?
Both report who a domain is registered with and its key dates. WHOIS is the original plain-text protocol; RDAP (Registration Data Access Protocol) is its standardised replacement, returning structured data over HTTPS. ICANN-accredited registries and registrars now provide RDAP, and Seorism uses it wherever a registry supports it.
Why are the owner’s details hidden?
Most registries and registrars redact personal information such as the registrant’s name, email address and phone number to comply with privacy laws like the GDPR, or because the owner uses a privacy service. Seorism shows registrant details only when the registry publishes them.
Does “No registration found” mean a domain is available?
Usually, but not always. Some registries hide reserved, premium or recently deleted names, so check with a registrar before relying on availability.
Why is my domain’s extension not supported?
A few country-code registries offer neither RDAP nor a public WHOIS service, and some offer only classic WHOIS, which Seorism can’t always reach. In those cases, use the registry’s own website.
