Subnetting is often the "wall" that stops aspiring network engineers in their tracks. It looks like a mess of binary code and math, but it is actually the most logical part of networking. If you are looking for an experience, this guide will walk you through everything from the basic bit to advanced VLSM. 1. The Foundation: What is an IP Address?
How many groups do you need?

Start at .0 and add your magic number repeatedly. Subnetting is often the "wall" that stops aspiring
The broadcast address is always one less than the next network ID. Quick Example: Subnetting 192.168.1.0 /24 into four groups. We need to borrow 2 bits (2^2 = 4). New mask: /26 (24 + 2). In decimal, /26 is 255.255.255.192 . Magic Number: 256 - 192 = 64 . Networks: .0, .64, .128, .192. 5. Guru Level: VLSM (Variable Length Subnet Masking) IP Subnetting from Zero to Guru: The Ultimate
How many bits do you need to "borrow" from the host side?
A true guru doesn't use the same mask for every subnet. allows you to use a /30 for a point-to-point link (2 hosts) and a /24 for a large department (254 hosts) within the same network range.
