ICANN policies are guidelines and rules established by the Internet Corporation for Assigned Names and Numbers to manage the global domain name system. These policies ensure that domain names are allocated fairly and efficiently, helping to maintain the stability and security of the internet. Additionally, ICANN policies cover various aspects, including the registration of domain names, the management of top-level domains, and the coordination of unique identifiers. By setting these standards, ICANN aims to promote competition and innovation while protecting the interests of internet users worldwide.
