Toppnivådomenenavneserver

Toppnivådomenenavneserver, often abbreviated as TLD name server, refers to the authoritative DNS servers responsible for handling queries for a specific top-level domain (TLD) like .com, .org, or .net. When a user types a domain name into their browser, their computer first contacts a root DNS server. The root server then directs the query to the appropriate TLD name server based on the TLD of the requested domain.

These TLD name servers hold the records for all domain names within their designated TLD. For instance, a .com TLD name server would know where to find the authoritative name servers for example.com. Once the TLD name server receives the request, it provides the IP address of the authoritative name server for the specific domain. This authoritative name server then provides the final IP address needed to connect to the website or service.

The operation of TLD name servers is a critical component of the Domain Name System (DNS). They ensure that domain name lookups can be resolved efficiently and accurately, forming a hierarchical structure that allows for the vast number of internet domains to be managed. Multiple redundant TLD name servers are typically operated for each TLD to ensure high availability and fault tolerance. Changes to TLD name servers are managed by ICANN, the organization responsible for coordinating the global DNS.
