Toppdomänsnamnservrar

Toppdomänsnamnservrar, often abbreviated as TLD name servers, are the authoritative name servers for a top-level domain (TLD). These servers are responsible for holding the DNS records for a specific TLD, such as .com, .org, or .net. When a user types a domain name into their web browser, the process of resolving that domain name to an IP address begins with querying these TLD name servers.

These servers act as the first point of contact in the DNS lookup process. They don't contain the full DNS records for every website within their TLD. Instead, they hold records that point to the authoritative name servers for the second-level domains (e.g., google.com or wikipedia.org). For instance, if you're looking up google.com, the .com TLD name server will direct the query to the name servers that are specifically handling the google.com domain.

The Internet Corporation for Assigned Names and Numbers (ICANN) oversees the TLD name server system. They delegate the responsibility for managing the name servers for each TLD to specific organizations or registries. These registries, in turn, maintain the crucial DNS information that makes the internet function. Without TLD name servers, the hierarchical structure of the Domain Name System would collapse, and users would be unable to access websites by their human-readable domain names. They are a foundational element of the global internet infrastructure.
