RDAP Lookup – Modern Domain Registration Data

Access structured, machine-readable domain registration data using the modern Registration Data Access Protocol (RDAP). The official successor to WHOIS with enhanced security, standardization, and internationalization support.

RDAP vs WHOIS: What's the Difference?

RDAP Benefits

Structured JSON format - Machine-readable for reliable parsing
Internationalization support - Better handling of non-Latin characters
Standardized responses - Consistent data format across all registries
Enhanced security features - Better authentication and access control
ICANN-mandated protocol - The official successor to WHOIS

RDAP is the modern, standardized replacement for WHOIS, offering structured data and better security.

WHOIS Legacy System

Plain text format - Inconsistent structure across registrars
Limited internationalization - Poor support for non-ASCII domains
No standardization - Output varies significantly between registrars
Basic security - Limited access controls and authentication
Being phased out - Gradually replaced by RDAP

WHOIS is still widely used but is gradually being replaced by RDAP as the industry standard.

Why Use RDAP?

RDAP (Registration Data Access Protocol) is the official ICANN-approved replacement for WHOIS. It provides structured, consistent data about domain registrations, with better security and international domain name support.
