RDAP and WHOIS domain registration data
RDAP is the modern structured replacement for traditional WHOIS. The OceanofTools endpoint first requests public RDAP data and can use configured WHOIS providers as optional fallbacks when a registry publishes limited information.
- Available fields can include registrar, registration and expiration dates, domain status, DNSSEC and name servers.
- Privacy laws and registry policies often redact personal contact information.
- Country-code domains may publish fewer fields or use a separate registry service.
Registration data is informational and may be delayed. Confirm critical ownership or expiration questions with the registrar or official registry.
Frequently Asked Questions
What is the difference between RDAP and WHOIS?
RDAP provides structured JSON data, standardized error handling and better internationalization. WHOIS is an older plain-text protocol.
Why is registrant contact information missing?
Many registries and registrars redact personal data for privacy and legal compliance.
Does an expiration date guarantee a domain will become available?
No. Domains may enter renewal, grace, redemption or registry hold periods before they can be registered again.
