ICANN's main role is to manage the uniqueness of domain names, ensuring each one represents a distinct individual or entity and supports a reliable internet naming system.
The primary concern of the Internet Corporation for Assigned Names and Numbers (ICANN) is to ensure that each domain name represents only one individual or entity. ICANN is responsible for the global coordination of the Internet's system of unique identifiers, which includes both domain names and IP addresses. However, when it comes to uniqueness, their particular focus is making sure that every domain name is unique. Domain names are the readable addresses used to access websites on the internet, and it's vital that each one is distinct to avoid confusion and ensure that internet users reach the correct website.
By maintaining a singular mapping between domain names and their respective entities, ICANN upholds the stability and reliability of the internet's naming system.
