What is Subnetting? - Subnetting Mastery - Part 1 of 7

This video will teach you the basics of subnetting. Every Subnetting problem will ask you to solve for one or more of seven possible attributes: Network ID, Broadcast IP, First Host IP, Last Host IP, Next Network, Number of IP Addresses, and CIDR/Subnet Mask conversions. This video explains what each of the attributes are.

What if there were a single video series that could make you a Subnetting Master? What if that video series were available for free, for everyone?

Look no further. This is it. This is video 1 of the series. The complete video series will make you a Subnetting Pro.

First, thank you SO much for this video series. Before watching, I had used Keith Owens, James Messer, and Jason Dion and all of them have their benefits in terms of detail or practicality. However, your video series absolutely solidified the practical application of subnetting as none of the others had. It just totally nailed it for me. I can do it now. Thanks again!
This leads me to a question. Is there a reason you don't list the seven questions in an order that would make the arrangement more sequential?
This pattern always leads to a 2/3 sequential relationship.
Two IP's in sequence, Three IP's in sequence.
Network/ First IP (2), Last IP, /Broadcast/Next Net (3).
For example:
Target: 10.1.1.37 /29
Network ID: 10.1.1.32
First IP: 10.1.1.33
Last IP: 10.1.1.38
Broadcast IP: 10.1.1.39
Next Network: 10.1.1.40
# Of IP's / Usable: 8/6
CIDR / Subnet: 255.255.255.248

For those who just got here, I assure you that you can learn subnetting with this guy! I've not found any paid or free content such well done and easy to understand, I really appreciate it. Thank you, Ed!

[Sneh-Chauhan]

I usually don't comment but this video deserves it. The series taught me in a way that I could do subnetting for an entire day without getting bored.

[connief]

I have had subnetting explained to me a half dozen times and still walked away scratching my head. I felt like such an idiot!! I don't feel like an idiot anymore. Thank you so much for being such an excellent teacher!

[mundoin]

Just started my CCNA. Man does it feel scary after my first 10 days. Subnetting in particular. You explained things that I couldn't understand 3 days in a classroom with a guy that is being paid to teach this to us. Thank you!

This is the best video on Subnetting and Subnet mask. I tried to understand these concepts multiple times from various people and resources but failed consistently to understand these concepts. By going through the series of videos - subnetting mastery, I am able to understand them just like that. Thank you so much and appreciate your efforts in making these concepts simpler.

[Arfiess]

You honestly need more view. No bad quality video of a piece of paper, no dude with horrible sounds quality in front of a white board doing horrible drawing, straight to the point, and simple to follow. You managed to teach me something that took my prof 4 weeks to barely scratch the surface. Thank you so much.

I'm studying for the Google IT Support Professional Certificate and this explanation is far better than the one provided in the course. Thank you! Liked and subscribed!

[ggelin]

I can't believe it!!! He is literally explaining and answering every single part of subnetting something that I have been struggling to find and to understand. Thank you very much, coach.

[MarcMasonMusic]

I'm Studying for CCNA. This was truly the Best explanation I have found!!! Thank you so much!

[hardeepd]

Why isn’t this the number one result when searching subnetting. So concise. Quality Production. I’ve seen videos with ten times the views with crap quality video and audio, confusing, and scrambled that I leave as confused or more than when I started. I literally send this link to everyone that asks for help with Subnetting. Thank you a thousand times over for this.

BEST BREAK DOWN OF SUBNETTING ON THE INTERNET!!! I HAVE BEEN SOOOO FRUSTRATED FOR THE LAST 2 WEEKS TRYING TO UNDERSTAND SUBNETTING BUT THIS VIDEO DEFINITELY HELPED PUT 2 AND 2 TOGETHER!! THANK YOU SOOO MUCH :)

[FBCN]

Found your videos after 5 weeks of working for Network + Cert. Your videos made more sense than the damned explanation Certmaster has for Subnetting, and the book I got had 3 questions and 1 PBQ regarding subnets on my network + test today and passed. highly doubt I would have passed if I had not found your videos. Thank you!!!!

[drushkyy]

[aireddy]

This is one of the best video series to understand details about subnetting, Eddie Your mission is to take complex concepts and explain them in a simple.

[theshark]

OMG, finally a video about subnetting that actually makes sense. The visuals helped a lot too. NICE 👍🏾

Currently studying for my Networking+ using Mike Myers' materials. Your stuff has been an excellent addition to my preparation, helping me to better understand these concepts. Thanks for all your hardwork!
