description: >-
  The Internet Assigned Numbers Authority (IANA) performs the global
  coordination of the DNS Root, IP addressing, and other Internet protocol
  resources. IANA maintains the protocol registries, top-level domain
  delegations, time zone database, and language subtag registry that the
  Internet relies on. Bulk registry data is published as machine-readable
  files distributed via rsync and FTP rather than through a public REST API.
