What is IANA?

Internet Assigned Numbers Authority(IANA) is one of the most historic institutions on the Internet. IANA is responsible for managing the root zone of the Domain Name System (DNS), coordinating the allocation of global Internet Protocol (IP) addresses, and managing the IP coding system. Basically, they are responsible for the maintenance and management of the technical functions that enable the Internet to function normally.

Functions of IANA:

1. DNS Root
   
   Root nameservers, which are at the top of the DNS hierarchy, are made easier by IANA. As part of the DNS administration process, IANA engages with top-level domain registrars, root nameserver operators, and ICANN policymakers.
   
   

2. IP Address
   IANA is responsible for coordinating the IPv4 and IPv6 addresses assigned by Regional Internet Registries (RIRs) around the world to large companies, operators, and ISPs. It also assigns autonomous system (AS) numbers used by various routing protocols.
   
   
   IANA coordinates the allocation of IPv4 and IPv6 addresses to big enterprises, carriers, and ISPs by Regional Internet Registries (RIRs) throughout the world. It also assigns autonomous system (AS) numbers to different routing protocols.
   
   

3. Protocol parameters
   The Internet Assigned Numbers Authority (IANA) is in charge of the management of URI schemes (Uniform Resource Identifiers) and character encoding for Internet use. IANA manages the protocol numbering system together with various standardization organizations.
