TopLevelDomainServers

TopLevelDomainServers are a fundamental component of the Domain Name System (DNS). They are authoritative DNS servers responsible for a specific top-level domain (TLD), such as .com, .org, or .net, as well as country-code TLDs like .uk or .de. When a user types a domain name into their web browser, the process of resolving that name into an IP address begins with querying these servers. Specifically, a recursive DNS resolver, often provided by an Internet Service Provider (ISP), will first contact a TLD server to locate the authoritative name servers for the requested domain's TLD.

The TLD servers do not store the IP addresses for individual domain names. Instead, their primary function is to provide the IP addresses of the authoritative name servers that hold the DNS records for domains within their designated TLD. For instance, a .com TLD server would direct the query to the specific name servers responsible for example.com. This hierarchical structure allows the DNS to efficiently manage the vast number of domain names on the internet. The management of TLDs and their associated servers is overseen by organizations like the Internet Corporation for Assigned Names and Numbers (ICANN).
