The Internet Assigned Numbers Authority (IANA) is a key organization responsible for overseeing the global allocation of IP addresses, management of domain names, and assignment of protocol parameters. Established in the early days of the Internet, IANA plays a pivotal role in ensuring the stable and secure operation of the Internet's infrastructure. Specifically, IANA administers various tasks, including the allocation of IP address blocks to Regional Internet Registries (RIRs), management of the Domain Name System (DNS) root zone, and maintenance of registries for protocol parameters such as port numbers and Internet Protocol (IP) address assignments. While IANA itself does not provide services directly to end-users, its coordination efforts are essential for the smooth functioning of Internet operations worldwide. Over time, IANA's responsibilities have expanded to accommodate the Internet's growth and evolution, making it a central authority in the global Internet ecosystem. s://www.iana.org/about
- Snippet from Wikipedia: Internet Assigned Numbers Authority
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols and Internet numbers.
Currently it is a function of ICANN, a nonprofit private American corporation established in 1998 primarily for this purpose under a United States Department of Commerce contract. ICANN managed IANA directly from 1998 through 2016, when it was transferred to Public Technical Identifiers (PTI), an affiliate of ICANN that operates IANA today. Before it, IANA was administered principally by Jon Postel at the Information Sciences Institute (ISI) of the University of Southern California (USC) situated at Marina Del Rey (Los Angeles), under a contract USC/ISI had with the United States Department of Defense.
In addition, five regional Internet registries delegate number resources to their customers, local Internet registries, Internet service providers, and end-user organizations. A local Internet registry is an organization that assigns parts of its allocation from a regional Internet registry to other customers. Most local Internet registries are also Internet service providers.
