It's D - the keyword is 'database'. IANA is just one of the organisations who provide a whois database. Whois Lookup "Whois is a query and response protocol used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. This protocol listens to requests on port 43 (TCP). Regional Internet Registries (RIRs) maintain Whois databases and it contains the personal information of domain owners. For each resource, Whois database provides text records with information about the resource itself, and relevant information of assignees, registrants, and administrative information (creation and expiration dates)."

The Internet Engineering Task Force (IETF) is an open standards organization, which develops and promotes voluntary Internet standards, in particular the standards that comprise the Internet protocol suite (TCP/IP).[2] It has no formal membership roster or membership requirements. All participants and managers are volunteers, though their work is usually funded by their employers or sponsors. The IETF started out as an activity supported by the U.S. federal government, but since 1993 it has operated as a standards-development function under the auspices of the Internet Society, an international membership-based non-profit organization.

IANA : The global coordination of the DNS Root, IP addressing, and other Internet protocol resources is performed as the Internet Assigned Numbers Authority (IANA) functions. About us We are responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated, and this coordination role is undertaken by us. Specifically, we allocate and maintain unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet. Our various activities can be broadly grouped in to three categories: Domain Names Management of the DNS Root, the .int and .arpa domains, and an IDN practices resource. Number Resources Co-ordination of the global pool of IP and AS numbers, primarily providing them to Regional Internet Registries (RIRs). Protocol Assignments Internet protocols’ numbering systems are managed in conjunction with standards bodies.
