Internet Assigned Numbers Authority

Welcome to IANA

The Internet Assigned Numbers Authority (IANA) is responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated, and this coordination role is undertaken by IANA.

Our Role

Specifically, IANA allocates and maintains unique codes and numbering systems that are used in the technical standards ("protocols") that drive the Internet. Our work touches on areas such as:

  • Domain Names
  • Number Resources
  • Protocol Assignments
