What is subnetting and why to subnet

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..

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 YouTube --- 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 YouTube Tutor in a Crucial Technical Area. You are a certain winner!!

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! :)

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

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 !

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

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

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.

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

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

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.

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

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

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

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.
