WHOIS & Domain Registration Lookup — frequently asked questions
What is WHOIS and RDAP?
WHOIS is a legacy protocol and database system used to look up registered domain ownership. Registration Data Access Protocol (RDAP) is the modern, secure, and standardized RESTful replacement mandated by ICANN that returns structured JSON records.
What information does this lookup provide?
The lookup returns the sponsoring registrar, domain creation date, last updated date, expiration date, authoritative name servers, and EPP status flags.
Why is registrant contact information often redacted?
Due to global privacy regulations (such as GDPR) and registrar privacy proxy services, individual registrant names, email addresses, and phone numbers are typically shielded from public query responses.
Is this query logged or tracked?
No. Unlike commercial domain lookup portals that track searches to front-run domain purchases, Sada Files queries official registry RDAP endpoints without saving or tracking any searched domain names.
Which top-level domains (TLDs) are supported?
All major generic TLDs (.com, .net, .org, .io, .dev, .app, .ai) and country-code TLDs participating in the ICANN RDAP bootstrap registry are fully supported.
