About RDAP

The Registration Data Access Protocol (RDAP) is a modern protocol designed to replace the traditional WHOIS protocol. It provides a standardized way to access domain registration data, offering more structured and secure data retrieval.

RDAP supports internationalization, secure access, and standardized responses, making it a more robust solution for accessing domain registration information.
