!!! 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!
Thanks you for watching!
@@sunnyclassroom24 You are the best 😀.
Because unlike Caucasian, Asian get straight to the point. Fact! Not racism!
@@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! %)

Its like he is giving out gold for free.
This man is brilliant. His knowledge and ability to explain it in a way that is actually understandable is unmatched on RUclips.
"Because computer A is dumb..." paused and still laughing. :)
indeed!
Same!
Network ID and Host ID. Why has this never made any sense until now.... Sunny dude! Finally get it! Thanks!
I believe this is the simplest way to subnet ever!
I think so too :)
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
Hi Sunny Sir, this Noor from Afghanistan and really like this video please share more videos
love phone and internet hack
@@sunnyclassroom24 nicely done!!
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.
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).
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..
One of many hidden gems on RUclips!
Thanks, Sir!
many thanks.
The only video in RUclips explains what Subnetting is. I have zero knowledge on this subject and understood subnet in one go. Thanks for this video!
Glad it was helpful!
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
Thank you, what you thought me in 8 minutes I didn't learn in one semester in the university :))
Thank for for your compliments!
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.
Taught me**
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!!!
Finally a video that explains why subnet mask is needed. Everyone just go directly to the exercises. Thank you very much!!!!
This is the go to channel for all things networking
brilliant explanation!! I have seen a million videos on subnet mask , but only understood it after watching this video
Glad it helped!
Thank you so much for your videos. They are immensely helpful
I *almost* skipped because I thought his "Chinglish" would be too hard to follow.. Turns out that The excellent manner he explains topics, and the examples make it one of the easiest to understand tutorials I have seen THANK YOU SIR!
Wow, thanks!
Very Good English. Most Excellent Teaching Method. Thanks, Mr. Sunny.
You are welcome! Thank you for watching!
i have been trying to understand subnetting for 2 months, you made me understand it in less than 10 minutes, thank you sir.
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!
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
This is by far the best explanation of subnetting I've come across. Thank you so much Sunny
Glad it was helpful!
These videos are the best videos I've found on RUclips in regards to Networks!
Thank you very much for your compliment and nice comment, Jay!
No question! Give me the Sunny Method any day! Putting networking in SIMPLE terms is a gift! I'm going to bingewatch all 139 videos this weekend.
This man nailed it. He is a superman. What a teacher you are sunny.. cleared my concepts. Thanks alot
It finally clicked for me with this video. Great explanation, thank you!
love phone and internet hack
bruh im out here tearing my hair out bc i couldnt understand this or any other video's explanation but Sunny out here doing it better than most
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.
Great video! But the way it ends on a cliffhanger is too funny. Makes you feel like you have to go to next video immediately! So, on to the next one!
Give this man a medal !
Finally an explanation of the "why" that makes sense. Thank you.
That was an excellent explanation. I never quite understood the shorthand version of subnet mask but now understand it clearly. Thank you.
Wonder explanation with crystal clear example. Thank you very much..

Thank you for watching!
The best explanation on subnet I have found online so far. Thank you Professor Sunny!
I wish all my professors explained like you, Sunny! Thanks a lot!
You are welcome!
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?
Thanks again sunny. Your easy to follow and give a clear train of thought in these videos.
Glad you like them!
Very simple and easy to understand - Sunny Sir is the best
Thanks a lot for your kindness.

Sonny my IT brother, thank you. I got it - subnetmask allows computer to know is the target computer local or remote.
Thank you Sunny, your table is amazing. Very helpful.
I am glad you like it!
Thank you for clarifying with the Note that 00001010 was wrong because it was driving me crazy. I watched it over and over going that's not right. It is all good. Love your video and the simplicity that you explain things.
Thank you very much for your comment. I try my best to simplify things. Once we understand them, then go deeper. That is the way I like.
bravo job, clear and simple teaching method
Just found the channel and subbed. Great video, I hope I can learn a great deal from you.
Thanks for the sub!
Sunny - I want to thank you so much for all your simple to understand examples AND for explaining it as well (your chinglish is Awesome do not worry about it ) I subscribed today and will be looking to your class videos for my learning and hopefully going into CCNA with this information - just have to remember it all somehow :-) But I love all the classes that I have watched so far.
Glad it was helpful!
THANK YOU SOOOO MUCH SUNNY I finally understand this.
I love this guys style..wow!! Refreshed my memory to the core.
Thank you!
Wow this is incredible, thank you so much I was having a hard time figuring out exactly how subnet masks worked.
Your channel is such a hidden gem, subbed!
Sir, AGAIN, You are the best !!
Yay for visuals!! I understand subnet masks better now.
Glad to help!
- every host has an IP address and a subnet mask
- 32 big long, same length as an IP address only ones and zeros
- the prefix or slash shows how many ones and the rest are zero
- used by computer ls to see if another computer is local or remote
Thank you Sunny!
😂😂thank you for watching!
definitely a fan of Sunny's way.
