DNSHierarchie

DNSHierarchie refers to the hierarchical structure of the Domain Name System (DNS). The DNS is organized like an inverted tree, with the root domain at the very top. Below the root are the top-level domains (TLDs), such as .com, .org, and .net, as well as country code TLDs like .uk or .de. Each TLD can contain numerous second-level domains, which are typically the names registered by organizations or individuals, like "google" in "google.com". Further levels, called subdomains, can be created under second-level domains, allowing for further organization. For example, "mail" could be a subdomain of "google.com" forming "mail.google.com". This hierarchical design allows for a distributed and scalable system for translating human-readable domain names into machine-readable IP addresses. Each level of the hierarchy is managed by specific servers. Root name servers know where to find the servers for TLDs, and TLD name servers know where to find the servers for second-level domains, and so on. This delegation of authority is fundamental to the operation of the DNS.
