Twenty years ago, choosing a domain name was simpler: there were only a few popular zones like .com, .net, .org and national domains for different countries. But today the internet includes addresses with extensions such as .shop, .art, .blog, .online, .app and even .pizza or .coffee. It may seem that a domain can be any word, and there is some truth in that. However, the process of creating a new domain zone is not chaotic and follows clear rules. Understanding how names after the dot are formed and who approves them is possible thanks to an organization without which the modern internet would not exist.
