This dude explained a topic in 8 mins what my college proff couldn't in a semester.

Did my man just damn near draw a perfect circle without a compass????

Give this man a raise! It kills me when professors don't explain THE WHY when explaining concepts. This is so helpful, thank you.

I actually Had this guy as a teacher/director of my networking course. He is far more amazing in person..

Straight and clear cut explanation unlike many text books tutorials that are too technical.

Great video man. My head was scrambled with the maths before I even understood what subnetting is

I don't know which one I applaud more. His elegant explanation of the topic, or that his freehand circle and sectoring drawing! Both are excellent!

Berry, you are the man! You are so correct, Mr. Berry Smith. What and why subnetting ? ! Everyone else --- EVERYONE on KZfaq --- rolls over that crucial question / topic / insight except you. Students know how to "mimic the numbers" as you say, but they lack an independent understanding. They cannot see the forest because there are too many trees. My light-bulb (admittedly dim) was activated by your observations. In sum, my humble and enthusiastic thanks to you. YOURS was the key video explaining WHY. Excellent. It's so much easier now (post Berry Smith video) to get into the weeds and understand splitting up addresses on the router for the reasons of (1) security; (2) organization; and (3) performance. THANK YOU. I subscribed and thumbs-up to you. I'm now heading to your playlists to see all the other vids you have in this networking area. I'm nominating you for an Oscar as Best KZfaq Tutor in a Crucial Technical Area. You are a certain winner!!

3 years ago i saw this video and that time I was so happy because he explained it very well. Now I'm watching this again coz I decided to pursue my career in networking

I always come back to this before an interview! The best subnetting video there is!

Why do we subnet; S: Security O: Organization P: Performance SOP = Slice Of Pizza. This man is a genius.

If you need to know more about subnetting and this is the first of Berry's videos you've come across, I STRONGLY advise you to watch all of his videos on this subject matter! Berry is a great teacher! I thought subnetting would be a subject I would never really be able to grasp based on how others have explained it. Then, I found Berry's videos and improved my knowledge greatly because of Berry. If you are reading this Berry, thank you so much for your help! :)

Sir you have just saved my life with these videos. Thank you for making it so approachable!

Finally, someone who knows how to explain IT concepts in a simple way…Great content!!!

Flawless execution sir. I tip my hat in your general direction!

Well done! I knew it must be easier that these other fellows made it seem. Some can explain simply, and some cannot; it’s a gift. You have it.

after reading 1 whole chapter for this i now understand it more clearly! thank you for your direct concept.

I was searching for "why" all day. Thank you so much.!

Basic but powerful explanation. I really appreciate your knowledge sharing. Thank you so much!!!!!

Very good explanation of Subnets - thank you for putting it in plain English!

Thank you for actually explaining what is in the first place. Instead of jumping from how we get a subnet mask, I would like to first know what the hell it's even for or why it exist.

Thank you for taking the time.! As you said most people skip this crucial part. Things make more sense to me now.

Excellent lesson! Thanks for explaining, helps with my IT studies. Nice freehand circle by the way

I never seen any such a wonderful session in my life. You are awesome!!

wow! it was like a piece of Pizza.. wonderful explanation of subnetting!! Thanks for making it so simple to understand.

Really enjoyed the demonstration and just want to thank you for explaining it in a easy way

Thank you very much for making this so clear. this entire series is a godsend.

Berry, Thank you very much for a nice breakdown of the subnetting and its benefits. That pizza analogy is brilliant.

Awesome video that explains a complex concept in less than ten minutes

Wow, I finally understand subnetting. I've been watching a whole bunch of other videos but this one is the one that helps me understand subnetting. Thank you!

Wonderful explanation. With that real life pizza example learning became more concrete and easy to remember. Thank you.

Although I watch most of the videos at 1.5 times of the original speed, I couldn't do it this time. I liked how you taught and made jokes in between and kept my attention till the end. It was magnificent.

I have seen more than an hour of Eli the computer guy videos over and over again, I didn't understand anything and Mr. Smith explained to us clearly in 8 minutes, Thanks.

Utterly fantastic explanation! Thank you so much for uploading this.

Every networks student deserves a lecture like you💯. Thank you.

Love your teaching style, much needed. easy to understand with a real time example.

Wow, thank you! Such a great and simple explanation. I had been scared away from even touching subnets and I knew there would be a decent explanation on KZfaq. I'm actually excited to watch your other videos!

I don't think you can get a better explanation on subnet than this. Great work Berry! & the analogy :)

Great Educator. Thank you Mr Smith.

You got a new subscriber today. Will most definitively go throughout the rest of your videos. Thank you.

I've never come across an explanation on subnet as clear and enjoyable than this. Great work bud ! :)

I learn from analogies much easier. I appreciate you doing this video! Thanks. Great job.

great explanation and simple explanation to get the concept right. When I talk to network admins to explain things, they kind of make things more complicated and does not want to share knowledge.. Hats off to Berry !

Perfect video man!. I mean I have gone through series of videos regarding this but nobody had the same clarity to explain this like you have.

Great video! I'm a few years into my it career and now I understand subnetting better.

Great video. I really appreciate you breaking down subnetting into what and why topics.

Brilliant, thank you for spending time to create and share this. The best video I’ve seen on subnetting

Thank you, this is exactly the position I'm in right now. Doing an online course right now and the last hour or so has been "here's how to subnet and here's a quick way to subnet" without any explanation of wtf subnetting actually is or is used for. Exactly the video I needed!

You are a fantastic teacher. Thanks for sharing your knowledge!

You are the best Ive watched all your videos and the way you deliver the info is perfect pls dont stop teaching ever

Thank you. I loved your presentation. I agree with you that it's important to know the WHY we are doing it.

Thank you for this video. It helps to understand why we use subnets. Your video helped me grasp the overall concept of subnetting. Thank you :)

Thank you. As a non network person this answered my question beautifully.

Man, this was a fantastic explanation. Loved it.

Yes, very clear answer. You explained it well and it was easy to understand and remember. Where the reside on the OSI model was great information, Thank you!

Thank you for this video. Explained very well and straight to the point.

You deserve more views my guy. Thank you for everything. Sharing this.

Finally someone who explains why do we need things and not just explain without any reasoning behind! Good job!! Keep up the good work!

Excellent video. As a software developing seeking to refresh my memory on basic networking concepts, I've found the content in this video to be very well balanced. Normally I don't bother commenting on videos, but I felt this was good (I've not watched the series) that it warranted a comment. Keep up the good work. Like most fields, there are people that excel within them but are lousy at transferring that knowledge over to others, especially if they learn slightly differently. Finding teachers that can pull that off are rare indeed.

This is great! You're the man. So informative.

wonderfully gifted instructor. It took me years to understant this piece of pizza until now.

Oh my god THANK YOU. I have been struggling with this concept since I started learning networking and you explained this so well. Thank you so much!

Superb explanation.The analogy you used is simply awesome

Amazing video! Thanks so much for this! Sir, you are a fantastic teacher!

Network management is also a good reason to mention here, which is related to the organizational structure of the company. I guess you could consider that under organization but we use the term network management quite often and I believe that it should be mentioned as a term or reason. Great presentation overall!

Very simple and crystal clear explanation of Pizza sub netting .This round pizza makes me understand about sub netting

Excellent example with the pizza! Made me understand a lot of things I didn’t understand before!

This is the best video I've seen on this topic. Good work!

You really got it to the point and explained the most important question... WHY SUBNET? Thank you so much for this video! Subbed!

This was an awesome video! The breakdown simplified the concept so much!

I found this while taking the Google course, you explained it so much better than them. Thank You.

I’ve watched so many videos on subnetting, and this is the only guy who bothered to actually explain what it is and why you would use it. I personally need to know the why to learn the how, so this was awesome.

"I was told how but wasn't told Why" Encapsulated my entire experience trying to learn this aspect of networking. Thank you Berry!

Super easy to follow explanation! Thank you.

Brilliant explanation. Really happy you talked about why it was important and why we use it, since that information seems scarce! Thank you so much.

i love the analogy, thanks for the why of subnetting, thanks a lot, now im moving to the other videos, thanks a lot.

Thank God. Best explanation on overall concept of subnetting.

You made it so much easier to understand. Thank you so much.

When you said professor teach you how to subnet but not why it was as if you read my mind. What's worse is I can ask my professors to explain it and it just made things so confusing. Thank you for posting this!

Berry, what a brilliant explanation you have given.. I have subscribed so i don't miss any of your future tutorials..

Berry Smith, you're supper star! Thanks for the teachings.

Thank you so much! Your explanation is so easy to understand!

Very good job explaining !!! made it simple and to the point !!!!

Excellent explanation and Thank you for making this video.🙏👍

This is great. Thanks , Prof. Smith!

Awesome Awesome Awesome video. Thank you very much Berry for such an explanation. Your one video cleared all of my doubts

You explained this so well, I'm not a computer guy whatsoever. I'm trying to get into cs, subscribed!!

You made this incredibly easy to understand, thank you so much.

I just discovered this channel. I am learning AWS and these explanations are another level. Hope you are doing good and will start to make more of these videos @Berry Smith !

Excellent teaching skills, well done

Thanks so much for this video! The pizza analogy really helped .

i am a student in germany and i gotta say... THANK YOU! that was a great help and you are so charming

This man is incredible. Thank you!

Thanks my Teacher Berry Smith! You are an awesome teacher

Thanks..at my job I was asked to be a tech and I have had most of my experience in PC and software implementation. Recently our only network administrator quit - being the only tech there- now they have me trying to learn. They wont hire a network guy although we support over 600 people..I just started to jump in to even understand what subnettimg is..as I notice many folks on different subnets but definitely its disorganized at the moment from your video

Excellent explaination 👏. Thanks for the video 👍

I don't know why.. but you're the only one who explained this in an Understandable way..

This is a wonderful explanation, thank you VERY much!

Great explanation, sir! Thank you!

Appreciated. Explain really easily anyone can understand... Thanks alot. Subscribed 🙌🏼
