RDAP (Registration Data Access Protocol) is a modern protocol for accessing registration data for domains, IP addresses, and autonomous system numbers. RDAP is considered a newer alternative to WHOIS and is used to retrieve structured information about a domain, such as status, dates, nameservers, registrar details, and related contacts/entities (when available under zone policies).
In simple terms, RDAP is a “modern WHOIS” with a more standardized and developer-friendly format. Unlike traditional WHOIS, RDAP often returns structured responses (usually JSON), making it easier to automate, integrate into APIs, and process in domain lookup tools and services.
RDAP is a modern domain lookup protocol and service used to retrieve registration data. It provides domain information in a more structured format than traditional WHOIS.
WHOIS often returns unstructured text that can vary by domain zone. RDAP uses a more modern approach: standardized responses (usually JSON), links to related objects, better machine readability, and easier data handling for automation.
RDAP commonly provides domain status, registration and expiration/update dates, nameservers, registrar details, domain events, and related entities (contacts), when those details are not hidden by privacy policies or specific registry rules.
