How DNS Works | Understanding DNS Architecture | DNS Types Explained | Part I

In this informative video, we delve into the fascinating world of Domain Name System (DNS) and explore how it works. DNS plays a crucial role in the functioning of the internet, acting as a translation service between human-friendly domain names and machine-readable IP addresses. Join us as we unravel the mysteries of DNS architecture, hierarchy, decentralization, and the various types of DNS.

🌐 DNS Architecture: Hierarchical and Decentralized 🌐
We start by examining the hierarchical nature of DNS architecture. Discover how the DNS hierarchy is organized into different levels, including the root level, top-level domains (TLDs), second-level domains, and subdomains. Gain insights into how DNS servers interact with each other to resolve domain name queries efficiently. Understand the significance of authoritative DNS servers and recursive DNS resolvers in this complex system.
