I just say a huge thank you! I never could grasp the concept of Subnetting before. And was afraid I might not be able to continue with the Cybersecurity field if I couldn't figure it out. So, I just want say thank you so much for breaking it down like this. The rulers and the 5 basic steps (hand) really helped me connect some of the dots in my mind. Look forward to checking out more of your subnetting and other helpful networking tips and tricks.

This is a very fun learning and nobody explains it better than Keith. This foundation will serve us great for the life of our IT career.

Keith, at 8:30 AM on Jan1, 2025, after I had a cup of coffee, I was listening to someone review subnetting on LinkedIn. I was snoring by 9AM, and slept until 1 PM.(I have a an new Cure for insomnia). It is now 12: 25 AM and I just completed Subnet Saturday # 1 and am fully awake and engaged. Thank you for being selfless and making these videos.

Your way of teaching is not only fun to look at and listen to but also the most effective I've seen. Thanks Keith!! Love these videos!

I have been watching subnetting bootcampts for weeks now and this simple visualization helped me 10x more than anything I have been watching thank you!!

[ChasedWheels]

Oh man, teaching IP addresses using the ruler was simply an awesome idea. I had never seen someone explaining like that. thanks

[luisgutierrez]

Keith, I have clicked on a couple of your videos here and there while looking at how to do a task but have never finished the videos BUT now that I'm actually enrolled in school for a few IT certification and got stuck in IP subnetting.... did some research and ran across a recommendation from a post I read in "Reddit". As of today, you have just become my #1 instructor for the CCNA. I just finished watching the IPv4 Basic and I'm hooked. I'm so excited that you have the whole CCNA series...over 175+ videos. Thanks for putting out these videos and thanks a million for all that you do for the network community.

I've learnt this by my own before coming here, but believe me dude u have been the only person that had explained this so clear, and direct to the Point, when I was looking for a good understanding of this topic I wish I could seen you before, anyway ppl this guy ROCKS!! Greatings from Nicaragua you have gainend a new subscriber!! Blessings!!

[FTroopF]

Great stuff....thank you. I wish I had found you 15 years ago.

You're a good instructor. Your enthusiasm is contagous and it's clear that you've put a lot of time and effort into how to best deliver the info.

The use of rulers really illustrates your point well, and quickly. I love the home-made, telescopic, color coded subnet mask teaching aid.

Good on you for what you're doing to help people here on YouTube...for free.

I'm subscribing and have already visited CBTNuggets....which I would never have found if not for your free content. Thank you

[mohamedabdi]

pure and simple indeed, thanks a lot Mr. Keith Barker, we really appreciate your sacrifice. sundays program is helpful for poor communities in the world who cannot afford CBT Nugget. Godbless you with speed

[wolfferoni]

I've gotta say, I've been studying IT for a while and networking has always been a little dry and confusing to me, until now. I love your enthusiasm and the way you explain concepts. It encourages me to learn more. Thank you for making these videos, I look forward to watching more.

[gauravdesai]

Being into Networking.. I still find this is so far the finest way to make one understand. Thank you keith

[logenninefingers]

Hello Keith, I just started watching your videos yesterday. The way you teach is undoubtedly brilliant, I plan on taking the CCNA exam in mid-2021.

[khalifakhalifi]

Oh dude! I love your CCNA Labs and how you explain things, definitely learnt more with your videos than with my teacher :D My field is more sys admin related, but needs obviously networking skills. You basically have been a very important part of my learning path! Thank you!

[TheBeach]

Thanks for sharing. I really needed this. I work as Network Admin and this really helps getting the basics down in a fun but effective way.

[njj]

This is the easiest way to understand IP address I've ever seen! Thank you so much.

[DPGkilla]

Thanks Keith. Another fantastic watch. You make it so simple to understand. Especially the subnetting using your fingers that i have seen you do

[kharingSFO]

I absolutely love your videos and your CBT Nuggets courses. You've simplified many concepts for me and given me a better understanding of the topics. Please keep up the awesome work...and thank you!!
