Linda has a Bachelor degree in both IT and Accounting and currently works in the IT industry. Since 1998 she has also worked as an online writer for companies such as About.com and Suite101.com. By putting all her skills together from her accounting (math), IT (computers), and online writing (educating), she has designed a course for beginners on subnetting and hopes to create more courses in the future.

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.
Introduction to the course.
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.
There is a second part to an IP address known as a subnet mask. Find out how the subnet masks that go with your classful IP addresses.
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.
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.

There was a little too much time spent on basics (binary numbers, hex, etc.) -- anyone who is studying for a Network+ or Cisco cert should already have that stuff down pat. However, it was a decent refresher of the mechanics of calculating subnets.
Great course to gain the basics of subnetting. Easy to follow. There were a couple things I would have liked explained a little clearer such as the IPv6 subnets when the /xx bits are not divisible by 4. However, if you are understanding the material you will be able to figure it out. I would recommend this course to my peers.
Only a few lectures in and I already know way more than the almost nothing that I knew previous to me taking this class. I can only look forward to the rest of the lectures and the knowledge that I will gain!
