Internet Corporation for Assigned Names and Numbers

The Internet Corporation for Assigned Names and Numbers (ICANN) is a global multistakeholder group and non-profit organization headquartered in Los Angeles, California, United States. Established in 1998, its core mission is to coordinate the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, thereby ensuring its smooth, secure, and stable operation. ICANN's primary principles include preserving the operational stability of the Internet, promoting competition, achieving broad representation of the global Internet community, and developing policies through bottom-up, consensus-based processes.

ICANN's key services encompass the allocation of Internet Protocol (IP) address space for both IPv4 and IPv6, protocol parameter assignment, and the management of the Domain Name System (DNS) and root server system functions. It oversees the distribution and allocation of IP addresses through five regional internet registries and administers the DNS through accredited domain registrars. This includes managing generic Top-Level Domains (gTLDs) and country code Top-Level Domains (ccTLDs), ensuring unique domain names and IP addresses are maintained globally.

ICANN operates as a 501(c)3 organization, funded primarily by fees charged to domain registrars and domain name registrations. On October 1, 2016, the organization formally transitioned from U.S. government oversight to global multistakeholder community governance, solidifying its role as a public-private partnership. The current leadership includes Kurt Erik Lindqvist as CEO and president, and Tripti Sinha as Chair of the Board. ICANN continues to engage in initiatives such as Universal Acceptance readiness, collaborating with various global partners to ensure all valid domain names and email addresses are universally accessible.
