Company Overview

ICANN (Internet Corporation for Assigned Names and Numbers) is a nonprofit public benefit corporation founded in 1998 with support from the U.S. government, headquartered in Los Angeles, California, USA. Internet pioneer Dr. Jonathan Postel played a pivotal role in its establishment. As a key coordinating body for global internet infrastructure, ICANN is responsible for managing the Domain Name System (DNS), IP address allocation, and root zone file management — the critical resources that keep the internet running globally.
