Frequently Asked Questions
What is RDAP and how does it replace legacy WHOIS?
Registration Data Access Protocol (RDAP) is the modern RESTful HTTP/JSON successor to port 43 WHOIS, offering standardized structured data, cryptographic security, and internationalization.
Why is domain registrant personal contact information often redacted?
Under ICANN regulations and privacy frameworks like GDPR, domain registrars automatically redact personal names, home addresses, and phone numbers from public query responses.
How can I check when a domain name expires?
The registry RDAP output provides authoritative expiration, initial registration, and last modification dates directly from the official Top-Level Domain registry database.
