Domain Information

IANA is responsible for the operation and maintenance of a number of key aspects of the DNS, including the root zone, and the .intand .arpa domains.

The DNS Root Zone IANA is the global coordinator of the DNS root. The root is the upper-most part of the DNS hierarchy, and involves delegating administrative responsibility of top-level domains, which are the last segment of a domain name, such as .hamburg. Part of this task includes evaluating requests to change the operators of country code domains, as well as day-to-day maintenance of the details of the existing operators.
