Secret of subnet mask

!!! Correction note: from 5:09 to 8:09, Computer A's IP address' fourth octet in binary should be "00000010". Sorry about the confusion.
----------------
Every host on a network has IP address and subnet mask. What is subnet mask? Why does a computer on a network need a subnet mask? What does a subnet mask look like? How does a computer knows whether its target computer is local or remote? What is the secret? In this video, you may find all these questions.
This is my education channel. My topics cover networking, security, programming, and other computer-related materials.
Please subscribe my channel. Many thanks.

I've been a network engineer for 6 years and I've NEVER heard someone explain networking this simply! I understand more than ever haha!

[@sunnyclassroom24]

Thanks you for watching!

Because unlike Caucasian, Asian get straight to the point. Fact! Not racism!

[@ph8632]

@@pizzainc6926 No..... That is racism. And not anywhere near the truth. I have had instructors from all kinds of backgrounds and there are good and bad in all of them. You just showed you are the bad apple of the bunch. I dont care what your skin color is, you reek of racism.

its even simple with bad english, respect! %)

[@DrGaryButtman]

This man is brilliant. His knowledge and ability to explain it in a way that is actually understandable is unmatched on KZbin.

[@veronicaschmidt2659]

I believe this is the simplest way to subnet ever!

[@sunnyclassroom24]

I think so too :)

[@Rajeshdas-pb7nd]

Sir I wanna ask you something in PC A's ip is 10.1.151.2 and its subnet mask is 255.255.255.0. Shouldn't it be 255.0.0.0 as it is a class A ip address? Or is it a classless subnet mask ? Please do clarify

[@elmiramoayedi7653]

Thank you, what you thought me in 8 minutes I didn't learn in one semester in the university :))

[@sunnyclassroom24]

Thank for for your compliments!

[@rl751]

That's how you know that's a great teacher. When they make scary subjects like computer networking seem simple, approachable and make sense to total beginners.

[@playingforyou9635]

Taught me**

[@curtvincent3355]

For decades I have used the question "What is a subnet mask and why do you need one?" I have been shocked at the answers I have gotten by senior people. They have never learned it as a bit level like Sunny teaches. When you see it at the bit level, everything clicks regardless if IPv4 or IPv6. I like Sunny, he breaks things down into easily digested chunks. When I am building a new team of cyber people, I make them watch Sunny's videos as the man is smart, humble and knows how to communicate. Well done Sunny. Oh, and BTW, your binary mistake is irrelevant to the network number so your instruction is still valid.

[@kenpomaster20]

I completely agree! I've been trying to understand subnetting for my Network + exam for months. Thanks to Sunny, I've learning how to subnet easily in about 20 minutes (adding his last video into the mix).

[@thelostmarbles4310]

I still ask 'what is a subnet mask and why do we need one'... Why do we need subnet mask if we can arrange subnets with vlans and ips? Why do we need to know the network portion and the host portion of the subnet mask if the network portion and the host portion are ALREADY on the ip addresses? Doesn't make sense..

[@qkcb]

One of many hidden gems on KZbin! Thanks, Sir!

[@sunnyclassroom24]

many thanks.

[@rabbitcreative]

"Because computer A is dumb..." paused and still laughing. :)

[@sunnyclassroom24]

indeed!

[@astevenswrites]

Same!

[@hackingnut4164]

Network ID and Host ID. Why has this never made any sense until now.... Sunny dude! Finally get it! Thanks!

[@james400414]

You are by far the best at simplifying explanations that others make seem difficult. PLEASE keep the videos coming. Thank you!!!!!!

[@bigbrothercopacagrana618]

The best explanation on subnet I have found online so far. Thank you Professor Sunny!

[@jenniferboone83]

Love this guy! 🤯 I have had a hard time understanding subnetting but today I feel like I can conquer it after watching just 2 of his videos. Well done!!!

[@Carmadd74]

Hey Sunny, I'm new to IT and I love your videos! I subscribed to your channel today. I love the humor and how you make computer language/processes so easy to understand. Keep doing what you do, I'll keep watching and learning. Thank you.

[@kevinmanuel6711]

Thanks for the video!!! It is really helpful. The way you present it in Audio and Visual is perfect. Audio = Your English is really good, clear pronounciation, the speed is okay. Visual = The Animation is cool man. you are really a modern teacher. I found it's not a piece of cake to do that animation. The way you teach is really effective. You've made this lesson as simple as possible

[@anilkommalapati6248]

Awesome and in a word GREAT video. I went thru many sites and videos but your videos relates to ssl certs, subnetmasks are outstanding. I can confidently say YOUR VIDEOS ARE THE BEST. The way and style of your explanation on complicate topics can be understood even by toddlers. You are a computer GOD.

[@SlayTeddies]

You, Sir, are amazing! You explain so clearly what I couldn’t understand when I read about it in a textbooks or listened to wasteful lessons. Thank you!

[@BeardoComputes]

It finally clicked for me with this video. Great explanation, thank you!

[@oz12353]

[@bhuvaraga]

The only video in KZbin explains what Subnetting is. I have zero knowledge on this subject and understood subnet in one go. Thanks for this video!

[@sunnyclassroom24]

Glad it was helpful!

[@send2gl]

That was an excellent explanation. I never quite understood the shorthand version of subnet mask but now understand it clearly. Thank you.

[@sks220]

sunny you're a godsend, just got out of my networking class having no idea what was going on and now I'm caught up in less than 20 minutes (watched your subnetting is simple video too) thank you!

[@jondoh2226]

Finally an explanation of the "why" that makes sense. Thank you.

[@ximonarcayera6237]

Watched a ton of long videos and reached this 9min gem and I can say this is definitely the best way to learn subnet mask

[@ivarellefsenmentz7446]

i have been trying to understand subnetting for 2 months, you made me understand it in less than 10 minutes, thank you sir.

[@vasellmarjunits205]

Sonny my IT brother, thank you. I got it - subnetmask allows computer to know is the target computer local or remote.

[@anastasiskarlis1282]

Simple explanation to the point. You're a legend sunny.

[@ukuempress6508]

Thanks! Gladly I found your video. I had some hard time watching others' explanation and browsing the web. You are able to clear away my confusion in just 2 minutes!

[@pblintso]

Me finding this channel is like hitting a goldmine! It is rare to find tutorials that fit my non-technical learning style - slow, clear, straightforward. This channel is great for building and strengthening foundational knowledge. Thank you, Sunny, for the wonderful way you present your content! What specifically is the subnet mask "masking" or covering? Also, how come the comparison is only done for the network part and not for the host part? Is it because checking host is not necessary as a computer can tell whether the target computer is local or not based on the network part?

[@divinesreeram]

Wonder explanation with crystal clear example. Thank you very much..
