Did You Know? IP Addresses Have Classes! 🌟 How devices find each other on the internet? It all starts with an IP address — a unique identifier for every device online! Back in the day, IPv4 addresses were split into 5 classes to manage networks of different sizes: 🔹 Class A: 0.0.0.0 – 127.255.255.255 → For huge networks (think big corporations!) 🔹 Class B: 128.0.0.0 – 191.255.255.255 → Perfect for medium-sized networks (like universities) 🔹 Class C: 192.0.0.0 – 223.255.255.255 → Ideal for small networks (your home Wi-Fi!) 🔹 Class D: 224.0.0.0 – 239.255.255.255 → Used for multicast (one-to-many communication) 🔹 Class E: 240.0.0.0 – 255.255.255.255 → Reserved for experiments & future tech 💡 Fun Fact: Today, we mostly use CIDR (Classless Inter-Domain Routing) for smarter, more efficient IP allocation! #TechTalk #Networking #IPAddress #IPv4 #ClassA #ClassB #ClassC #CIDR #LearnTech #InternetBasics

DNS (Domain Name System) is like the internet’s phone book. You type a website name, DNS finds the right server behind the scenes, and boom, the page loads. Why DNS matters: ✔️ No need to remember IP numbers ✔️ Faster and smoother browsing ✔️ More reliable websites #dns #InternetBasics #networking
