Domain Name System (DNS)

As an essential part of a URL ( Uniform Resource Locators), a domain tells us where a resource is located in the structured hierarchy of the Domain Name System (DNS) . The translation of a domain into IP addresses is carried out using this system.

These are specialized web servers responsible for resolving names and IP addresses. This service works in the same way as telephone information: the user types the domain name www.example.com in the search bar of his web browser and the latter will send a request to the appropriate server name.

This is where the entry www.example.com will be loaded into the database and will transmit the registered IP address to the browser.

For Example: https://example.com

The URL contains two parts:

  • The protocol (https:) is a set of criteria for the browser to send the request to the server.
  • Domain, example.com or the URL of the main website. The domain consists of two parts:
    • The TLD (Top Level Domain), which is part of .com (or other domain extension ), and
    • SLD (second level domain), themes, namely, from your registrar domain name .

The subdomain contains the second name before the SLD. For example, if the example blog is hosted on https://blog.example.com or you create a website on blogger.com with your domain name for example “helopanda” then your domain comes with “blogspot”.( Helopanda.com = Helopanda.blogspot.com) the blog/blogspot will be a subdomain.
