Internet Corporation for Assigned Names and Numbers (ICANN)

The Internet Corporation for Assigned Names and Numbers (ICANN) is one of the international organizations in the Internet field established in 1998. As a non-profit organization, ICANN's mission is to maintain the safe and stable operation of the global Internet unique identifier system. On the Internet, for many devices to find each other accurately, they must be assigned an identifier, and each device's identifier must be unique so that there is no confusion. To this end, the inventors of the Internet designed the IP protocol, which uses a set of numbers as an identifier for networked devices, which is what we often call an IP address. In order to facilitate users' memory and use, technical experts have designed the Domain Name System (DNS), which uses meaningful and memorable domain names to point to an IP address, such as entering www.icann.org. You can visit the ICANN website without having to memorize its IP address: 192.0.32.7. ICANN is the organization responsible for coordinating global domain name and IP address management policies.
