Learn Subnetting5:14
Subnetting Secrets has been designed to help you learn to subnet in just a few short lessons. It is designed to help you quickly and accurately get to the answers so you can apply them to networking exams and technical interviews.

If you can tick boxes then you can learn to subnet using my proven formula.

Class C - 25 Bit Mask2:30
How to find an IP address in a Class C subnet with a 25 bit mask.
Class C - 26 Bit Mask2:03
Class C - 27 Bit Mask3:08
Class C - 28 Bit Mask2:14
Master class c subnetting with a 28-bit mask, determine host addresses, calculate /28 increments of 16, and identify broadcast addresses for exam-ready subnet calculations.
Class C - 29 Bit Mask2:25
Explore class C subnetting with a 29-bit mask, determine subnet increments from 24 to 29, and identify the host address 200.155.80.
Class C - 30 Bit Mask2:48

Class B - 17 Bit Mask2:02
Class B - 18 Bit Mask2:12
Discover how a class B subnet with an 18-bit mask yields 64-block increments, creating 150.200.0.0/18 and 150.200.64.0/18 networks, and how to identify the network for the example address.
Class B - 19 Bit Mask2:00
Demonstrate applying a 19-bit subnet mask to a class b network, calculating the subnet, host addresses, and broadcast across octets. Explain determining the first and last hosts within that range.
Class B - 20 Bit Mask2:13
Learn class B subnetting with a 20-bit mask, using increments of 16 to determine subnets and identify the first host and broadcast addresses.
Class B - 21 Bit Mask2:10
Analyze class b subnetting with a 21-bit mask to determine subnet increments and host ranges. Practice applying the last-two-octet approach and exam-style calculations to identify valid subnets.
Class B - 23 Bit Mask2:06
Class B subnetting with a 23-bit mask, tracing subnet increments and identifying the first address within the subnet for an exam-style question.
Class B - 24 Bit Mask1:52
Master subnetting for class B networks using a 24-bit mask, enabling efficient IPv4 address planning and subnet creation.
Class B - 25 Bit Mask2:23
Explore class B subnetting using a 25-bit mask, calculate incremental subnets, and apply zero subnet as well as fourth octet and third octet rules to determine host ranges.
Class B - 26 Bit Mask2:48
Explore class b subnetting with a 26-bit mask and learn a quick method to compute the network and host portions by stepping in 32-bit increments across octets.
Class B - 27 Bit Mask2:43
Class B - 28 Bit Mask2:30
masterclass on class b subnetting shows how a 28-bit mask builds from a 24-bit base and uses 16-address increments.

Class A - 10 Bit Mask2:14
Explore class a subnetting with a 10-bit mask by working through IP address 10.100.193, applying binary masks and 64 increment boundaries to identify hosts and broadcast.
Class A - 12 Bit Mask2:27
Learn class a subnetting with a 12-bit mask, applying increments of 16 to identify networks and host ranges, including subnet zero, first and last hosts, and the broadcast address.
Class A - 20 Bit Mask2:43
Class A - 26 Bit Mask3:05

Design Example 11:48
Design example 1 shows subnetting by selecting a mask to support at least 10 hosts per subnet and computing host bits in the last octet.
Design Example 21:39
Design example 2 shows borrowing four host bits to create a /28 mask, yielding 16 subnets with 14 usable hosts each to meet the nine-subnet, ten-host requirement.
Design Example 32:09
Design example 3 demonstrates subnet planning from a network address to create at least 30 subnets by borrowing bits to reach 32, with 11 host bits yielding 2046 usable hosts.

Wildcard Masks Example 11:20
Learn how to generate a wildcard mask from a subnet mask to match traffic from the given address block. See an example of deriving a wildcard mask for IP subnetting.
Wildcard Masks Example 21:03
Explore wildcard masks in ip subnetting with example 2, calculating the correct wildcard to match traffic from a net and aligning with the first column.
Wildcard Masks Example 30:54
Learn to create a wildcard mask to match traffic by rewriting a subnet mask into four columns and deriving the full wildcard mask.

Most IT Engineers Can’t Subnet…here’s why…

Understanding IP Subnetting is a vital skill for every IT engineer and yet most don’t know how to do it or go about it completely the wrong way. Once you understand a few simple techniques of this subnetting tutorial, you can actually easily subnet any IP address in your head.

Does this sound familiar?

“I have to use a subnet calculator to work it out”
“I can’t pass my exams because I am too slow at subnetting”
“I keep failing technical interviews because I can’t subnet”
“I’m overwhelmed as to where to start”
“I worry about looking stupid at work if there is a subnetting fault on the network”

This is where Subnetting Secrets comes in. When I left the police force and went into IT I used to dread subnetting but when I was forced to write some notes to teach a class one day I stumbled across an easy way to subnet. If you can count to eight in your head then you can use my method explained in this subnetting tutorial to:

Learn to subnet
Pass exams with ease
Answer technical interview questions with confidence
Quickly troubleshoot subnetting issues at work
Easily work out a simple subnetting design for your office network
and much more…

The techniques taught in this subnetting tutorial have been tried and tested by myself to learn to subnet, pass my MCSE, A+, Network+, CCNA, CCNP and many other non-IT exams as well as easily pass interviews for Cisco and BT. They have been used by many other students to effectively study for and pass their exams also. I know they will help you too.

What’s Included in the subnetting tutorial?

Subnetting Secrets includes:

Over 40 subnetting lessons in the pdf
Network design tips
The long and short way to subnet
VLSM lessons
Wildcard masking tips for access lists and OSPF
