What organization is responsible for website name registration?

The organization responsible for website name registration is ICANN, which stands for the Internet Corporation for Assigned Names and Numbers. This nonprofit organization oversees the allocation of domain names and IP addresses, ensuring that each domain name is unique and that the distribution of IP addresses is done efficiently.

ICANN coordinates the maintenance and procedures of several databases related to the namespaces of the Internet and is critical to the functioning and security of the internet as a whole. They also manage the global domain name system, which allows users to access websites using easily recognizable names instead of numerical IP addresses. Their role includes approving registrars which handle domain registrations and thus, they are the central authority in the complex system of internet naming and address allocation.

While other organizations mentioned handle different aspects of technology and communications—such as ARPA (known for advanced research projects), the FCC (responsible for regulating communications in the U.S.), and DARPA (focused on defense and advanced technology research)—none of them is dedicated to domain name registration like ICANN.
