Why not is internet administrate by any one?

The internet is not administered by any single entity because it is a decentralized network made up of numerous interconnected networks operated by various organizations, governments, and individuals. This decentralized structure promotes innovation, resilience, and freedom of information. Various organizations, such as the Internet Corporation for Assigned Names and Numbers (ICANN) and the Internet Engineering Task Force (IETF), help manage specific aspects of the internet, but no one body has complete control. This collaborative governance model allows for diverse participation and prevents censorship or monopolization.
