Whether you're just starting to learn subnetting or have been struggling with it for awhile, this guide will show you the easy way to learn to it and have you subnetting like a pro in no time. Starting with how to read binary numbers and IP addresses, you will then be walked through the process of breaking them down and creating any kind of network.
Learn to use the binary numbers that you will need when subnetting. Convert binary numbers to decimal numbers and back again. Step by step format to make it easy to follow along.
IP addresses used to be broken down into classes. Learn about IP address classification and how it's used.
Moving onto more modern IPv4 subnetting. You'll be learning about VLSM and CIDR which are the backbone of subnetting. Once you understand this, you'll be able to conquor subnetting.
Understanding the math behind the subnetting is important if you want to make sure you always get your subnetting right. This will walk you through how the math works with three very different examples.
Now that you understand the way subnetting works, I'm going to show you something that will make your life a little easier.
Get out your calculator or pen and get ready to practice converting binary numbers to digital numbers and back again.
The first 10 questions will have you deciding whether an IP address is Class A, B, or C. The Next 10 will ask whether the IP address is in a reserved range or not.
This will test how well you remember your powers of 2.
10 question quiz to make sure you understand slash addressing and route summarization.
These are the same questions from the subnetting videos, but don't cheat, see if you can come up with the answers on your own this time.
Just a little extra to make sure you understand the numbers behind subnetting.
Learn to read and write hexadecimal numbers so you can subnet in IPv6.
IPv6 addresses are very long, but there are ways to shorten them.
A prefix length is similar to the IPv4 subnet mask, learn how to use it.
Learn how to do basic IPv6 subnetting. The different parts of the IPv6 address are discussed, and then you're shown how to break it down into subnets and host IDs.
When you're finished learning subnetting and think you really have a thorough understanding, you're ready to move onto more advanced CCNA training. Here are my recommendations for CCNA training courses for you here on Udemy.
