The Registration Data Access Protocol (RDAP) is a standardized, structured protocol designed to replace WHOIS, offering more consistent, secure, and policy-compliant access to domain registration and Internet number resource data. As RDAP increasingly supports differentiated access—where users are granted varying levels of data visibility based on their identity, role, and purpose—there arises a strong operational…

The adoption of the Registration Data Access Protocol (RDAP) as a modern alternative to WHOIS is not solely a matter of technological evolution; it is deeply intertwined with the complex and often fragmented international policy landscape that governs privacy, cybersecurity, data protection, and internet governance. As a protocol designed to deliver structured, secure, and extensible…

As the Registration Data Access Protocol (RDAP) becomes the mandatory and preferred method for retrieving domain and IP registration data, ensuring high availability (HA) of RDAP services is paramount for registries, registrars, regional internet registries (RIRs), and other operators. RDAP serves as a critical information gateway for law enforcement, security researchers, compliance auditors, and domain…

The Registration Data Access Protocol (RDAP) is designed to deliver domain name and internet number registration data in a secure and standardized way, succeeding the legacy WHOIS protocol with improvements in data structure, internationalization, and security. Among the various mechanisms available for protecting RDAP services, Mutual Transport Layer Security (mTLS) authentication provides one of the…

Zone files play a central role in the Domain Name System (DNS), listing authoritative records for domain names under a specific top-level domain (TLD). These files are essential for resolving domain names to IP addresses and ensuring DNS resolution works reliably and securely across the global internet. However, errors, inconsistencies, or outdated data in zone…

The Registration Data Access Protocol (RDAP) has emerged as the standardized method for accessing domain name and internet number registration data, offering structured responses, differentiated access control, and improved security features compared to its predecessor, WHOIS. However, as RDAP becomes a regulatory requirement across gTLDs and IP address registries, ensuring that implementations remain compliant with…

The Registration Data Access Protocol (RDAP) has become an invaluable asset in the cybersecurity domain, particularly in the context of threat intelligence and incident response. For cyber threat hunters, integrating RDAP into operational playbooks allows for the structured, real-time retrieval of domain and IP registration information, offering critical context in investigations of malicious infrastructure, phishing…

The Registration Data Access Protocol (RDAP) represents a modern, structured, and extensible approach to accessing domain and IP registration data. As the successor to WHOIS, RDAP offers a flexible foundation for both standardized and customized data interactions. One of its most powerful features is extensibility—an attribute that allows registrars, registries, and network operators to tailor…

As the Registration Data Access Protocol (RDAP) becomes the standard mechanism for accessing domain name and IP address registration data, the need for secure, privacy-compliant, and user-friendly authentication mechanisms for RDAP access portals has become increasingly evident. RDAP portals are critical interfaces that provide authenticated users—such as registrars, law enforcement, cybersecurity teams, and intellectual property…

The Registration Data Access Protocol (RDAP) offers a structured, secure, and extensible mechanism for retrieving domain name and IP registration data, presenting it in a standardized JSON format that is both human-readable and machine-processable. As RDAP has been increasingly adopted across gTLD and ccTLD registries, regional internet registries (RIRs), and other operators, it has laid…
