These videos are so great. You can go back after you forgot this and it all comes right back. The best subnetting explanation out there.

[Modassirhassan]

You have no idea sir, what have you done by illustrating Subnetting in so easy language! I have been trying to understand it for weeks, searched so many videos on YouTube but you're the only one who has cleared my doubts!
Thank you so much!

[TriviumDFTS]

I've been on and off studying for my CCNA for almost a year now. I've recently had time to get really serious about it due to COVID.
These videos have helped TREMENDOUSLY. This series is a must have for subnetting. Thank you!

[chriszale]

Life Changing am a noob IT guy, and starting with Network + . The videos, along with the practice site have made subnetting completely "click" for me! Thank you!

[lukemalby]

Legend! These videos are the best resources to learn subnetting by far. I have literally tried just about every method and found this one the easiest, quickest and with the least chances to make a mistake. Appreciate your work!

[PracticalNetworking]

Who knew subnetting in the 3rd octet would be just as easy?

[sabrinasegura]

First… THANK YOU. I was taking a class and literally stopped and rethought my entire career change based on how subnetting was taught..until now! What I don’t understand why on 3 octet broadcast ends in .255 and last host on .254. And then first host is .1. Ya lost me there 😢. Thanks again! I have already sent the series to a ton of friends!

[jeffgowell]

These video's convinced me I can do subnetting at 60 years old with NO IT experience !!! I'm going to check and see if there are more videos like this on DHCP and DNS which is kicking my ass LOL

[emileakuamoah]

This guy here is genius. So far this's the best series of subnetting i have seen so far.

[toastymcgee]

You...are amazing. How is it that everyone has a different method of understanding and explaining this process? This is easily the most straight forward and easy to understand which is really what matters here.

[engralikhan]

Well beyond the approach of any professor or instructor. You are doing a brilliant job. Well done

[jimboelterdotcomm]

So many training materials just discuss how to handle the 4th octet, and leave you floundering when you need to solve problems for the higher ones (I know, the principle is still there, but it's a little slippery for those of us coming to subnetting in later years). Appreciate your taking the time and energy to deal with
3rd octet problems.

[chickenonbeachball]

for 2 weeks I tried to get m head around subnetting, your video has done it in under an hour. Thank you.

[jameselrick]

I literally can't thank you enough for your video's! It's been rattling in my head on how to do sub-netting for months now, but thanks to you and your websites! I've been able to do quick pulls on sub-netting in 30 seconds! That's a fantastic improvement, and I for one can't wait to go take my net+ now! Thank you again, and you got yourself a new subscriber.

[israelflores]

This....This is so STUPID I can not believe how much I have stressed over subnetting for my CCNA. A very BIG THANK YOU! THANK YOU! THANK YOU!

[willgreat]

Made the third octet look easy, I’m glad they are not gonna ask me to do any 2^n notation without a calculator I would fail .

[bit-BlackCascadia]

Absolutely the best way of learning to subnet. You rock. Huge Thank You. I have learned to subnet in a day.

[RohIt_bhopali]

[libaaxalee]

Without a doubt to me this is the easiest way to subnetting, appreciate your help.
