The 4 Key DNS Servers in Loading a Webpage

  1. DNS Recursor
    The DNS recursor is a server designed to receive queries from client machines, such as web browsers. It handles the task of making additional requests to satisfy the client’s DNS query. It acts as the first point of contact for a DNS query, similar to a librarian tasked with finding a specific book in a library.

  2. Root Nameserver
    The root nameserver is the initial step in the process of translating human-readable host names into IP addresses. It serves as a reference point to other, more specific DNS servers. It can be likened to an index in a library that points to different racks of books.

  3. TLD Nameserver
    The Top-Level Domain (TLD) nameserver is responsible for handling the last portion of a hostname. For example, in the domain example.com, the TLD nameserver would be for “.com”. It can be compared to a specific rack in a library that holds books from a particular category.

  4. Authoritative Nameserver
    The authoritative nameserver is the final stop in the DNS query process. It contains the specific DNS records for the requested domain. If the authoritative nameserver has the information, it provides the IP address back to the DNS recursor. This server is akin to a dictionary on a library shelf, offering the precise definition or IP address for the requested hostname.
