How Does Variable Length Subnet Masking (VLSM) - Solved Problem 1 Work?

Variable Length Subnet Masking (VLSM) is like giving different sized backpacks to kids so they can carry just what they need for each trip.

Imagine you're organizing a playdate, and you have 16 toy boxes, these are your IP addresses, like the toys kids bring. At first, you might divide them into groups of 8, 4, or even 2, using fixed-sized backpacks (like traditional subnetting). But what if some kids only need a few toys for their game, and others need more?

That's where VLSM comes in, it lets you give different sized backpacks, so each kid can carry just the right amount of toys. You don’t have to waste space with bigger backpacks when smaller ones are enough.

You start by picking a big group (like 16 toy boxes), and then you split them into smaller groups, maybe one group gets 8 toys, another gets 4, and so on, all based on how many toys each kid needs. This way, you use just the right number of toy boxes for every game, making it easier to manage everything.

It’s like having different sized backpacks that fit perfectly, no more too big or too small!
