RDAP: Replacement for Whois service

From documentation

The Registration Data Access Protocol (RDAP) is the successor to WHOIS. Like WHOIS, RDAP provides access to information about Internet resources (domain names, autonomous system numbers, and IP addresses). Unlike WHOIS, RDAP provides:

A machine-readable representation of registration data;
Differentiated access;
Structured request and response semantics;
Internationalisation;
Extensibility.
