The Internet Assigned Numbers Authority (IANA) is a key organization responsible for managing and coordinating some of the essential functions that keep the internet running smoothly.

It oversees the allocation of global IP addresses, the management of domain name system (DNS) root zones, and the assignment of protocol parameters used in internet standards.

IANA’s role ensures that IP addresses and domain names remain unique and consistent across the global internet, preventing conflicts or duplication.

Operating under the Internet Corporation for Assigned Names and Numbers (ICANN), IANA plays a crucial role in maintaining the stability and interoperability of the internet’s infrastructure.
