DNS Domain Structure | Domain Name System | Mastering BIND DNS Server

In this video, we will explain the concept of domain structure and how it works.
A domain structure is a hierarchical naming system used to organize websites and other internet resources.
It allows users to access resources on the internet by using domain names instead of IP addresses. Here are the key concepts of domain structure: Top-Level Domain (TLD): This is the highest level of the domain hierarchy and includes domain extensions such as .com, .org, .net, and many more. Second-Level Domain (SLD): This is the level below the TLD and is the main part of the domain name.
For example, in the domain name example.com, example is the SLD. Subdomain: This is a third-level domain that is used to organize different sections of a website.
For example, blog.example.com is a subdomain of example.com. Fully Qualified Domain Name (FQDN): This is the complete domain name that includes the TLD, SLD, and any subdomains.
For example, www.example.com is a FQDN. Domain Name System (DNS): This is a system used to translate domain names into IP addresses.
When you type a domain name into your web browser, the DNS system looks up the IP address associated with that domain name and sends you to the correct website. In summary, the domain structure is a hierarchical system used to organize and access resources on the internet.
Understanding how the domain structure works is important for anyone who wants to create a website or work with internet resources.
