Subnetting & VLSM Made Easy | Variable Length Subnet Masking(VLSM)

Are you confused about Subnetting in Classless Addressing? 🤔 Don’t worry! This video will give you a step-by-step explanation of CIDR (Classless Inter-Domain Routing) and VLSM (Variable Length Subnet Masking) with easy examples that even beginners can understand.

In traditional classful addressing, subnetting wastes IP addresses. But with CIDR and VLSM, we can efficiently allocate IP addresses, reduce wastage, and design optimized networks. This concept is extremely important for exams like DSSSB TGT Computer Science 2025, UGC NET, GATE, NIELIT, and other competitive exams where Computer Networks is a key subject.

👉 In this video, you will learn:
✔ Basics of CIDR Notation (like /24, /27, /30, etc.)
✔ Subnetting in Classless Addressing step by step
✔ How VLSM allows creating subnets of different sizes
✔ Real-world examples of CIDR & VLSM used in networking
✔ Quick tips to solve Subnetting questions in exams

This tutorial is designed for students, networking beginners, and competitive exam aspirants who want to master subnetting in the easiest way possible. By the end, you’ll be able to calculate subnets, IP ranges, and broadcast addresses quickly without confusion.

If you are preparing for DSSSB TGT CS, GATE, UGC NET, NIELIT, SSC JE, or any Computer Science exam, this video will boost your Computer Networks preparation and help you solve subnetting problems with confidence. 🚀
