52. Subnetting in Classless Addressing | Divide a CIDR Block | Computer Networks

How do you divide a Classless IP block into even smaller subnets? In this Computer Networks tutorial, we tackle Subnetting in Classless IP Addressing (CIDR Subnetting). We break down the exact mathematical steps to borrow bits in slash notation, calculate new block sizes, and find the IP ranges for your newly created subnets.

Key Concepts Covered:

The difference between Classful Subnetting and Classless Subnetting.

How to "borrow" bits and update the Slash Notation (e.g., dividing a /24 into four /26 blocks).

Calculating the number of newly created subnets (2^n).

Finding the new Block Size and Valid Hosts per subnet.

Finding the exact First IP (Network ID) and Last IP (Broadcast ID) for each subnet.

If you are preparing for GATE CS , UGC NET, or B.Tech Network Layer exams, mastering these numericals is absolutely essential for your success!
