Understanding DNS: The Phonebook of the Internet | Ethical Hacking Course Video #23

Welcome to Video #23 of our Full Ethical Hacking & Cybersecurity Masterclass! In this lesson, we explore one of the most critical components of the internet: the Domain Name System (DNS). DNS is often called the "Phonebook of the Internet" because it translates human-readable domain names into IP addresses that computers use to identify each other on a network. What you will learn in this video: What is DNS? An introduction to how domain names like google.com are converted into numerical IP addresses. Port Number: Why DNS typically operates on Port 53 using both UDP and TCP. How DNS Works: A breakdown of the recursive process involving Root Servers, TLD Servers, and Authoritative Nameservers. DNS Records: A brief look at common record types like A, AAAA, MX, and CNAME. Security Perspective: Why DNS is a common target for attacks like DNS Spoofing (Cache Poisoning) and how it affects overall network security. About This Course: Presented by Ai Learner, this series is designed to provide you with a solid foundation in Networking and Cybersecurity. Mastering DNS is a crucial step for any ethical hacker looking to understand how traffic is routed and manipulated on the web.
