What Is ICANN?

ICANN — the nonprofit organization that coordinates the DNS root, IP address allocation policies, protocol parameter registries, and accreditation for generic-domain registrars.

A registry, registrar, ICANN, and IANA perform different roles. The registry maintains the TLD database, the registrar serves the customer, and coordinating organizations define or administer broader policy and technical parameters.
