RDAP Lookup
Registration Data Access Protocol — structured, JSON-based domain registration data. Falls back to WHOIS when RDAP is unavailable.
About RDAP
RDAP (Registration Data Access Protocol) is the modern replacement for traditional WHOIS. It provides detailed and structured domain registration data — ownership, registrar, name servers, and important dates (creation, update, expiration).
Unlike WHOIS, RDAP returns data in a standardized JSON format, supports internationalization, and is more secure and reliable. This tool uses RDAP to give you real-time domain details, and automatically falls back to WHOIS if RDAP data is not available.
