Introduction0:27
I introduce myself, my background and why we need subnetting.

Binary calculations6:55
I explain how the binary numbering system works and how to convert between decimal and binary numbers.
Conversion between binary and decimal
The continous flow of ones and zeros5:01
Learn how a subnet mask look like in binary. Understand the rules of a valid mask and differentiate those from invalid masks.
Make them decimal3:08
Converting binary masks to decimal is not harder than any other binary numbers.
See if you can spot valid and invalid subnet masks in binary
Prefix notation0:25
Quiz: Prefix notation

Supernetting5:33
Supernetting is the opposite to subnetting. When you supernet you group together multiple subnets in one definition, for example in route summarization.
The old classfull netmasks5:27
A short history lesson about classfull netmasks.
24 bit example2:57
Start simple, here we look into how a /24 works and looks like.
29 bit example4:45
We look into a smaller subnet.
Subnet further...7:56
What happens when we cut a subnet in halves?
The cheat sheet1:02

How many usable ip addresses in the subnet?3:41
Find out how many usablet addresses there are given a specific subnet or prefix.
You split the available range of addresses into smaller subnets.3:53
A tricky question. Dividing a range in smaller parts gives us multiple networks. How big are they? Where are the borders?
Specific requirements for subnets.3:36
We have specific requirements, lets find the best solution.
Convert prefix to mask1:41
How we convert from a specific prefix to its corresponding mask.
Tricky question 11:49

Requirements

You need to know basic math, like adding 64 with 32.

No Powerpoints, no animations. With just a pen I will teach You how IP subnetting works. From binary math to subnet sizes and exam-like questions to verify Your achieved knowledge!

Remember! 30 days money-back guarantee with no questions asked. I want you to be satisfied with my course. No Happy - No Pay!

Also, please take advantage of the free previews to see way you will get.

After taking this course, which takes less than one hour, you will never again need a subnet calculator. Subnetting can be done without any online subnetting calculator, all you need is a pen and paper and you will be able to create your own cheat sheet. What is my subnet mask? How many usable addresses in my network? What is the broadcast address? All of these questions will be easy to answer after enrolling this course!

After each lesson there is a quiz that verifies the knowledge you just achieved!

This course is good for anyone that needs to fully understand subnetting, including CCNA students!

Updates:
2016-01-03 Re-recorded lecture about 24 bits example. Free preview!
