The Internet Assigned Numbers Authority, or IANA, is an organization responsible for managing key elements of the internet's infrastructure. It oversees the allocation of unique identifiers, such as IP addresses and domain names, ensuring that they are distributed fairly and efficiently. This helps maintain the stability and functionality of the internet, allowing devices to communicate seamlessly. IANA operates under the umbrella of the Internet Corporation for Assigned Names and Numbers (ICANN), which coordinates the global internet's domain name system. By managing these essential resources, IANA plays a crucial role in supporting the growth and accessibility of the internet for users worldwide.
