IP Addresses & Ports Explained for Beginners | Zero to Root How does the internet know exactly which device — out of billions — to send data back to? In this lesson, we break down IP addresses and ports using simple, real-world analogies: think of an IP address as a building's street address, and a port as the specific room inside it. No prior networking knowledge needed — this is built for absolute beginners starting their ethical hacking journey. What you'll learn: 🔹 What an IP address actually is (and why every device needs a unique one) 🔹 IPv4 vs IPv6 — what they look like and why IPv6 exists 🔹 Public vs private IPs — what your router is really doing 🔹 What a port is, and why one device can run many services at once 🔹 Common ports you must know: 80, 443, 22, 21, 53, 25 🔹 How IP + Port together form a complete destination (e.g. 192.168.1.15:443) 🔹 Why hackers care about open ports — and how port scanning fits into real attacks This is foundational knowledge for anyone learning penetration testing, ethical hacking, or cybersecurity from scratch. 📺 Subscribe for the full beginner-to-advanced pentesting roadmap. ⚠️ Educational purposes only.
