ICANN, or the Internet Corporation for Assigned Names and Numbers, is a non-profit organization that is responsible for the coordination of the global Internet’s domain name system (DNS), IP addresses, and other critical technical functions. ICANN was founded in 1998 and is based in Los Angeles, California.
One of the most significant responsibilities of ICANN is managing the global DNS, which is the system that translates domain names, such as www.icann.org, into IP addresses, such as 22.214.171.124. ICANN oversees the assignment of domain names and IP addresses to ensure that they are unique and can be accessed globally.
ICANN also coordinates the work of domain name registrars and registries, which are responsible for managing the registration of domain names and assigning them to specific IP addresses. This involves developing policies and standards for the operation of domain name registries and registrars, as well as ensuring compliance with these policies.
Another key responsibility of ICANN is the management of the root zone of the DNS, which is the highest level of the DNS hierarchy. The root zone contains information about the top-level domains, such as .com, .org, and .net, and their associated IP addresses. ICANN is responsible for managing the root zone and ensuring that it is updated and maintained to ensure the stability and security of the global DNS.
ICANN also plays a critical role in promoting the development and use of new domain name extensions, such as .app, .shop, and .blog. These new domain name extensions are designed to offer greater choice and flexibility to website owners and users and help promote innovation and competition in the domain name industry.
Overall, ICANN is a vital organization in the functioning of the global Internet. Its work in managing the DNS, coordinating domain name registration, and promoting the development of new domain name extensions is critical in ensuring the stability, security, and accessibility of the Internet for users worldwide.
