What Is IANA (Internet Assigned Numbers Authority)?

IANA

Overview of IANA (Internet Assigned Numbers Authority)

The Internet Assigned Numbers Authority (IANA) is a key organization responsible for coordinating global IP address allocation (together with Regional Internet Registries), managing the DNS (Domain Name System) root zone, and managing IP numbering systems.

What’s Important About IANA

IANA’s work is critical for ensuring the stable operation of the global internet. By allocating and assigning unique identifiers like IP addresses and ASNs, IANA prevents address conflicts and ensures that networks can communicate with one another reliably.
