About iana
IANA, the Internet Assigned Numbers Authority, manages the DNS root zone, including assignments of country-code and generic top-level domains. It also maintains the .int and .arpa zones, a database of top-level domains, and an IDN practices repository.
IANA coordinates the global IP and AS number spaces, including allocations to Regional Internet Registries. It also serves as the central repository for protocol name and number registries used in many Internet protocols, and the homepage lists a Time Zone Database. The homepage text does not describe a query tool, pricing, or any user-facing service beyond these registries and assignment functions.
