RDAP is a modern and official replacement for the outdated WHOIS. This protocol provides accurate domain data directly from the registry and eliminates the drawbacks of traditional WHOIS: unstructured format, errors, and outdated information. With RDAP lookup, you will receive the current domain status, registration dates, DNS servers, and contact entities without caching or delays. Use RDAP as a more accurate, secure, and standardized alternative to WHOIS.
RDAP delivers domain data directly from the registry without using cache. This way, you get the most up-to-date values for status, registration dates, DNS, and contact entities — without the limitations of the old WHOIS.
Unlike the outdated WHOIS output, RDAP uses a standardized JSON format. Information is divided into clear sections: events, statuses, name servers, and contacts. This makes it more convenient, accurate, and easier to automate.
RDAP is a next-generation protocol developed by ICANN as a secure alternative to WHOIS. It uses HTTPS, supports authorization, provides a unified response format, and works correctly with international domain names. WHOIS is gradually being phased out, and RDAP is becoming the new standard of access to domain information.
RDAP (Registration Data Access Protocol) is a modern protocol for accessing domain information, replacing the outdated WHOIS / whois. It uses secure HTTPS, structured JSON, and a unified data format across all registries. Thanks to this, domain data becomes more accurate, up-to-date, and easier to understand.
WHOIS produces unstructured text that varies from zone to zone, is unsuitable for automation, and often contains outdated data. RDAP returns standardized JSON, supports international characters, authentication, links to related objects, and a unified response structure. RDAP was developed by ICANN as a modern replacement for traditional WHOIS.
Through RDAP you can learn the domain’s status, registration and expiration dates, DNS servers, contact entities (if not hidden under GDPR), event history, and links to related registry records. This is much broader and more structured than standard WHOIS output.
In most domain zones, personal data are hidden due to GDPR requirements. Unlike WHOIS, RDAP does not show outdated contact details — only what the registry allows: technical contacts, abuse contacts, and registrar information.
All gTLDs under ICANN are required to support RDAP and do so instead of WHOIS. Many ccTLDs, including .UA, have already adopted RDAP or are implementing it step by step. All data are loaded directly from official registry RDAP servers.
Yes. RDAP is specifically designed for automation, API integrations, and replacement of the non-standard WHOIS format. The response comes in JSON, supports pagination, links to related objects, and authorization features.
