A subnet is a logical subdivision of an IP network. The process of dividing a network into two or more networks is called subnetting. In this video, I will use an example to demonstrate a simple way of subnetting.
Some background links
• Tricks to five classes...
Example used in the video:
One day your supervisor walks to you, saying: “here is the network ID 192.168.4.0/24, please create three separate networks or subnets for a coffee shop: Sunny Cafe.” The three separate subnets/networks are: One is for the office, one for the front desk and storage room, and one is for public use.
Your task is to list each subnet network ID, subnet mask, Host ID Range, # of usable host IDs, and Broadcast ID. One last question: How many subnets are wasted after subnetting?
Subnetting Practice
With the same network ID: 192.168.4.0/24, you are required to get 6 subnets. List each of new network ID, subnet mask, host ID range, # of usable hosts, and broadcast ID. One last question: how many subnets are wasted after subnetting?
Answer for your reference:
We will have 8 subnets. subnet mask is /27 for all 8 subnets. The number of usable host IDs is 30 for all 8 subnets. I list below 8 subnets’ network ID,host ID range, and broadcast ID in the order.
#1: 192.168.4.0, 192.168.4.1-192.168.4.30, 192.168.4.31
#2: 192.168.4.32, 192.168.4.33-192.168.4.62, 192.168.4.63
#3: 192.168.4.64, 192.168.4.65-192.168.4.94, 192.168.4.95
#4: 192.168.4.96, 192.168.4.97-192.168.4. 126, 192.168.4.127
#5: 192.168.4.128, 192.168.4.129-192.168.4. 158, 192.168.4.159
#6: 192.168.4.160 , 192.168.4.161-192.168.4. 190, 192.168.4.191
#7: 192.168.4.192, 192.168.4.193-192.168.4. 222, 192.168.4.223
#8: 192.168.4.224, 192.168.4.225-192.168.4. 254, 192.168.4.255
tfw when you pay 10k a semester for school and a free KZhead video does a better job at explaining networking concepts than your professor
10k is too much for tuition. go to another school
damn 10K what ccountry ? in EU I pay 3K CS bachelor
The best teachers are KZheadrs! 😀
@@Omarismail-vs4jl I am an international student in Australia and I pay the same amount in USD
@@abiral933 in Australia they r business men, not teachers
Your accent is perfect and easy to understand - thumbs up
Thanks.
Agreed
Agreed! Thank you, Sunny!
You are also better to teach us more than the original one. Great job👍
Agree
Professor Sunny is a national treasure. A patron saint of Network engineers.
absolutely agree with that

It took me 6 months to learn and master subnetting. However, your video made it so simple. You made a huge difference. Students can learn so much from your subnetting videos instead of spending hundreds and thousands of dollars in the classroom. You are the best!
Guys help me I can't understand it😢
6:00 you explaind me in 6 minutes what my IT Teacher could not in a whole Year
Yes, sir, my professor couldn't explain it either, or I think these college instructors they DO NOT want you to learn, they do not want you to learn, I got so frustrated with It, they are a bunch of bozos, thank you, Sunny boy.
@@mattjoe67 you are welcome!
maybe you do not try enough. remember: Not always the blame is of the professor, most of the time is 1/2 on teacher and student. instead of complaining, try harder, work, exercise... That's my advice, that I follow myself.
@@marcolucas8192 I think in their case, the blame was 99% on teacher, or they woudn't learn it in 6 min. I believe teacher makes difference.
@@robson4028 There's plenty of other sources. How could it take an entire year to half-understand a basic concept?
I took a class on this and completely did not understand. I watched this video once and I'm able to subnet. This man deserves a Nobel Peace Prize. I love you Sunny!
"Noble Simplify Prize" I would say
Here also you have to oil someone to get likes!!!
i just watched neil anderson's explanation and this is better.
On each other requirement and process, there are plenty of other tricks and techniques on how to do subnetting in the wild. Knowing all of them can give you confusions and complications. But using this strong and well built table. It gives resolution in just a couple of minutes. I can say it's pretty impressive:> P.S. just use only what suites you up:)
Sure other ways was too complicated
This is insane! I have been studying subnet concepts for the past 4 days. I have been in a classroom for a total 8 hours this week. Read a full chapter twice and still could not totally grasp it. This video made the whole week! Thank you so much for the explanation. I guess I will start taking some time to see videos before attending class. BTW, your English is way better than most instructors. The pace made it a lot more easier to understand.
This is so much easier to understand than looking at a CIDR notation chart. Thank you for this!
And just like that, a whole semester of Subnetting confusing cleared up.
agreed same for me
Started it in class last week, been shitting myself.. now I'm like holy crap how easy it can be
Right??? Like I get that they want to teach us the barbaric way of doing things before telling us that we may never have to actually write out a subnet like this unless we were teaching someone it just to understand the where what and how of subnetting.... but geez at least make it easier to understand. This guy totally gets Teacher of the Decade Award 👏.
Can I ask what the purpose of the subnet is? Or why it starts at 24? Thank you again
@@Spellcaster12449 it starts with /24 because the network type he used to demonstrate is type C. We have variety of Subnet Mask types like A(255.0.0.0), B(255.255.0.0) and C(255.255.255.0). Type A Subnet Mask is /8, type B is /16 and, type C is /24. Where did those numbers come from? Well, technically they are the equivalent counts of their bits. Eight bits (11111111 binary) is equivalent to 255 in decimal so, (255.0.0.0) has 8 bits. For type B subnet mask(255.255.0.0), we have two 255s therefore 8 x 2 = 16, and since we have three 255s in subnet mask type C the answer will be 24 (8 x 3 = 24).

@@Laevatei1nn lmao
this guy was not lying, i actually understand it now!
It's never a bad idea to search for a great teacher! Not many have the gift of conveying information like you do Dr. Sunny ☀️
Sunny! I just got out of a Network+ exam which I passed, and memorizing your subnetting table and writing it down the moment I was allowed to write notes during the test was critical for answering 2 of the test questions correctly. Considering how close my passing score was, I give you and this video in particular significant credit for it. Thank you. Also, your accent - while very obviously Chinese - is clear enough that the *vast* majority of English speakers could understand it. So don't worry about the accent. Its certainly better than what I could do in any Chinese language or dialect!
you memorized the entire table?
I’m curious though, this helped me make a huge break through but how does it apply to Classful Subnet Masks /8 and /16?
@@robertkingjr313 same question have you figured it out
Fuck this video it literally blew my speakers out
@@lonelygoner2012 actually is easy considering values are in proportion of each other, double or half ..
Dude, this is killer. I have read probably 4 or 5 books on networking and never really grasped the concept of subnetting, but in 13 minutes you made it clear for me. Great work!
the same case with me, thank you Sunny
If you've in fact read 4-5 books on networking and still don't understand subnetting, you will never understand it. Consider reading something else :)
@@kalebs.gebrekirstos8041 man, what a douche thing to say.
lol, read less, do more.
@@kalebs.gebrekirstos8041He just said he understood subnetting after watching this video. Maybe you should read books on reading comprehension :)
Man @Sunny Classroom, I just have to thank you so much. I am bouncing between about 4 online CCNA courses, a few different KZhead videos, and online explanations, and I just could understand bits and pieces of subnetting. I picked up the binary conversions, how to turn a slash notation into decimal notation, etc. But I had a very hard time grasping the concept of how to lay out subnets from a single network ID. As someone with ADD, struggling every day to get this, trying to better myself, I am just so grateful that I stumbled upon this video. I literally just typed in Fun Subnetting on KZhead and your video was the first to pop up. You made this very simple as the video title states. I just opened up a word document, added a few tables, made the Sunny Table, and then did the rest, checked the video after to make sure I did it correctly. You are awesome!
This is now the third time I've learned subnetting. Once in college, once last year for CompTIA, and now I have to relearn it for my CCNA. I always refer back to this video. Thank you for uploading this explanation!
I thought I didn't have the brain capacity to process the concept of subnetting, maybe I'm stupid. but sunny has really pushed that information into my brain in a way that it is actually processing it. Thank you Sunny!

Same here!
When hundreds of people are complaining about how difficult it is to understand subnetting, it's probably not you.
Your "Chinglish" is epic. Thanks for helping me understand this, you're a true hero.
Got that from Black Lagoon?
nAmbers
Better than any explaination I've ever heard from a native english speaker. Thank you again.
Sunny, you are amazing! I've been stuck on subnetting for 3 weeks in college and all it took was one video from you to finally get it! Thank you so much for your videos!
Crying for that I finally understood this whole IP and Subnetting thing... I almost gave up on this. thank you!!! 🙏😍
He makes it look easy, but if you don't understand binary and can't tell the difference between the Host ID and Network ID you won't know what CIDR 26 means.
@@vincentmiller6957 just count the one's from the left, not a biggy
@@ahmadabdallah2896 Yeah, did that and was still lost😅. Subnetting isn't that easy unless you understand it.
Plz any one help me in this problem he is taken to 4 sub net so /26 taken in cases 3 sub net taken what I will I taken plz tell
Seriously me tooo
My understaning has been terrible no matter who explained this crap to me until now. Thank you Sunny! And yeah I cracked up at the chinglish comment too lmao
You are welcome! I am glad this method is understanding and comprehensible even in Chinglish.
Everyone else spoke Greek! finally, someone who speaks English, even with his accent, he spoke better English than others! Lol!
The chinglish is great, but that outro cracks me up everytime time. Thank u for the amazing content Sunny.
@@EduardoPereira-be2qy Thank you very much for watching videos.
SAME FOR ME
Prof. Sunny you have really explained this in a way that has allowed me to stop pulling out my hair. You sir are amazing!!! I tried many sources, and this was short, quick, but so impactful. Thank you so much!!!
5 YEARS AGO and still helping people out with this. Been scratching my head for months on this and watch your video and grasped more in 13min then I did many courses....Thank you.
There's nothing better than an EXPERT who can explain things in a clear, easy to understand way. Thanks, Sunny!!
Just like that, I understood subnetting in 13 minutes. Thank you for your very concise and clear explanations. This was so helpful.
You're very welcome!
@@sunnyclassroom24 You're honestly a lifesaver, Sunny. Or at least a sanity saver!
Totally agree with all the other comments here! Your video took a topic the textbook made overly complex and conveyed it perfectly in just 13 minutes. Amazing and incredibly helpful! Thank you, Sunny!
I will be honest your Chinglish is better than listening to a boring accent you are used to. Forces me to listen closely and gets in my head better!
This man should be knighted He has just explained this so damn well that I might have to find him and kiss him
Definitely! I dub thee Sir. Sonny.
Absolutely. I stumbled across his channel while searching for digital certificate video and now it seems like my mind is finally opening up in understanding all the networking concepts. His explanation is brilliant
How did it go.
gay
For real . Great great great explanation ✨✨
How can anyone dislike these videos. They are fantastic . Keep up the great work Sunny.
Thanks a lot for your encouragement!
Seriously how could someone dislike it, it also gives an useful insight that there r some people who don't like you anyway!!!
@@samudragupta719 you are correct.
@@samudragupta719 Some people are very picky or maybe got triggered by the sudden loud music in between.
@@Caution40404 and that inclined them to dislike the video?! They could have refrained from pressing any button (like Or dislike) !
You are an absolute legend! I was on my way to giving up on understanding subnetting, because the books overcomplicate it with the technical terms, but after watching the video not more than once, I fully understand subnetting. You have earned my subscription and I truly hope you keep creating such creative videos!
This was a lifesaver. Thank you very much for simplifying this process. I just couldn’t wrap my mind around how this is done until you showed it this way.
Oh man. I've spent days trying to understand subnetting 100% for my CCNA exam, I was almost giving up. In these 13 minutes you made everything clear for me. Thank you so so much!
How was the exam ?
My IT teacher directed my class to your channel because he loves the way you teach. You explained this wonderfully, I understood it so much better afterwards. Thank you so much for what you do!
It is always great to have alternative ways of explain subjects. Looking it from different directions is nice.
Crazy how 13 minutes has helped me understand more than multiple text books and classes couldn't. Thanks for the video.
They way you explained this was amazing. I had a hard time with this in class and was dreading the test. Watching your video made something click in my brain and I totally see this in a brand new way and it all makes perfect sense.Thank you so much!
This dude just blew all the subnetting guru out the water with this basic format.
If I had teachers like this in college I would have graduated Summa Cum Laude. Instead I had guys that couldn't teach, could hardly speak English or just read from a textbook. Though Sunny is not native English speaking, he is very easy to understand. Great job Sunny. You should be Professor.
Subnet Cum Laude :)
he is indeed, teaching in kansas
my computer science teacher would put Tom Scott videos on instead of teaching, i swear i'd be a genius if he'd put sunny videos on instead
Tell me about it. Had a guy who barely spoke English teaching us Calculus! :-(
I've been trying to wrap my head around subnetting until I came across your videos. You're just in a class of your own.
Having watched several yt videos to figure out subnetting, this is the only one that explains it clearly and coherently - bravo Sunny!
This is the best IP subnetting tutorial ever
I have worked in Networking as both a technician and an Engineer. He nails it. SIMPLE.
Thank you Sunny
I've been in IT for a looooong time and this is the simplest explanation and most valuable tool I've seen for subnetting ever. With the exception of perhaps very entry-level exams (I think), I've never had to know binary to decimal conversion for any reason except for subnetting. And now I don't even need it for that. Thanks Sunny. Best, Mike.
You are welcome!
Been working on Network+, and Subnetting has been a real challenge for me. You helped me finally grasp the idea. Many thanks!
After spending an hour looking at subnetting videos I can say this is by far the best explanation, thank you!
my heart is literally crying out of gratefulness, that teachers like you exist. God bless😭💛
There are many talented brilliant people out there, but unfortunately, you come across them too late. I've completed whole cisco routing semester, still was unable to create subnets so easy as watching just this one video. Sunny, many thanks to you for going out of your way to explain the subject so thoroughly. Keep up the good work
a year ago i was introduced to subnetting and i came to this video and was kinda better after watching you explain it. I am practiicng subnetting again , came back and finally understood it better after a year. Your video helped me back then and now . thank you sunny
I've been in IT for a long time and been watching subnetting explanation for the longest, this is the first time I feel like I got it. YT is better than most books and teachers. Thank you.
I owe my life to the sunny table
Sunny, you are amazing! Never apologise for your accent - I have never had someone explain these concepts as clearly as you. Thank you so much.
My Network professor kept saying how hard teaching subnetting was and would dumb down our lectures because of it. We then had to do a network design project, which due to our curtailed lessons, nobody knew how to do and our professor got annoyed because of it. This video explained it so clearly. Thank you, Sunny! I should be paying you my college tuition.
Bruh you are a lifesaver. I got to this chapter in my Comptia book and literally read it over 20 times and I still could not understand how they explained it. Thank you for showing me the Sunny Way!
Watching this 3 years later and all I can say is that you're a genius, Sunny! Thank you for breaking this down and making it easy for me to understand. You don't know how much this means to me. You're a life saver
In my networking class I took for 8 weeks as part of my IT course. I just couldn't understand subnetting to save my life it always throw me for loops. And now in 13 mins Bing the light bulb 💡comes on. I can not thank you enough for this video you made a complicated thing seem so simple to understand. I watched this video like 10 times and took almost 3 pages of notes of a 13 min video lol I love it.
I spent three hours on a CCNA course where he rambled about subnetting. This guy did it in 13 minutes
I wish you could meet you and hug you, man. This video is a piece of a treasure!!
Lol for a second there I thought you said piece of trash. lol
@@abubakarfarid2308 Haha - there's a typo too. The first "you" should be "I".
I loved how simple and dumbed down you made this. I was so frustrated with the answers my instructors were giving me. This helped fill in the gaps. Big thank you and the accent gave me confidence the video I clicked on was coming from a knowledgeable source lol thx bro
Hands down the best and simplest explanation of subnets and subnetting I''ve ever seen. Not all heroes wear capes...
Last time I did subnetting was back in 2015. Almost 8 years went by and I totally forgot how to subnet. I am preparing for my CCNA exam in a few weeks so I literally typed in "How to subnet" and your video was the first I clicked on. in only 13 minutes I remembered and understood how to subnet thanks to this video
Your 13 minute video is more clear than 13 hours of lectures. Thank you!
This was extremely helpful and far more simple than the others way I've learned. THANK YOU
I have read literally dozens of online resources attempting to explain subnets/subnetting. Every single one FAILS to explain how/why/what they are. Please continue to do simple explanations.
A colleague recommended this video. I could never grasp subnettting after watching several sources but this video made it sound insanely simple. Thank you
Nothing is wrong with your accent. Your video is the most understandable I have seen for this subject. Thank you for the time you have put in to make these videos. They are really helping me.
I am glad it helps. I appreciate your comment and it means a lot to me.
what to do when the subnet mask is /16 ??
You should get an award. Thank you for making this UNDERSTANDABLE! 🤯🤯
no joke, 5 years of books and slides with no use and this guy made me understand in 13 mins, this man is a treasure
This was made so simple, I felt like I just couldn't comprehend subnetting until this video...I wish teachers taught it this way. Thank you very much!
SUNNY!!!! I already “knew” what was on this video but didn’t understand. Your way of teaching is way better for how my brain learns. I’m really happy to find the right teacher because I have spent a LOT of time trying to understand concepts. My problem is that I can’t learn the rules, remember what to do and then implement what I learned. I have to understand what’s happening or my brain just farts. Thank you! I just took a screenshot of the Sunny Table, printed it out, & tacked it on the wall!
Your video on subnetting the best have seen so far. Great job!
Many thanks!
The best simple. Genuine method. Sunny, I appreciate you sharing your wisdom.
I appreciate your tip on the Sunny Subnetting Chart as well as your clear concise presentation.
You are my favorite technical resource on all of youtube. Thank you for all the great videos. I personally am a huge fan of the Chinglish.
I understand networking with granular details, but this was one of the finest visual presentations I've ever seen, it has easy to follow step by step algorithms, without having to know all of the arcane disciplines usually associated with basic networking. Great job!!!
This simple to understand method of teaching Subnetting is life saver. Love your Chinglish accent with easy to understand explanation . You deserved Nobel Prize as Charissa rightly said below. Thanks for sharing.
This is probably the single best explanation on subnetting I have ever watched. Thank you so much for this.
Currently taking an online course that doesn't always do a great job explaining new concepts. Subnetting was making my head spin until I found your video! Thank you so much, Sunny! Just subscribed and will be looking up more of your videos once I hit another bump in the coursework. :).
dang. This guy is on POINT! From his video itself, to the description, to the links, to practices. Thank you Sunny!
are so welcome!Thank you for watching!
Wow , I'm only halfway thru and this video answered ALL my questions. Sunny! The best! Subbed and liked! And shared
this is about the best explanation on subnetting i have come across on the internet ..........it just makes subnetting sunny the sunny way.
You are a hero, my IT teacher is explaining this for more than 6 months now, but youre video explained it perfectly in 10 min this helped me more then my school
This lesson was SO helpful in getting me to finally understand how to calculate sunetting. Thank you, Sunny!!!!
I've been struggling for months and bam! Less than 30mins I already know how to subnet with Sunny's way! Thanks you sir! You are the best!
You have demystified subnetting for a great number of people including me. Thank you very much for taking the time to make these videos.
the best teacher ever , R & S is now fun with sunny , who agrees ?
thanks a lot.
I do, it helps quiet a lot
This was soooo easy to follow!! Subnetting has been kickin my ass for 2 whole days. I even put off doing coursework until now because I was so discouraged...this has refreshed me and given me such insight. THANK YOU! -and your chinglish is perfect! lol
The best explanation and design method I’ve ever heard. Brilliantly simple. Thank you.
OH MY GOSH SUNNY! I AM NEW TO MY CYBERSECURITY DEGREE AND COMPARED TO EVERYONE ELSE I AM A NOVICE AND THEY NEVER LET ME FORGET IT. WHEN WE GOT TO THE CHAPTER FOR SUBNETTING I CRIED AND CRIED AND FELT SO DISCOURAGED BECAUSE I DIDN'T UNDERSTAND IT ALL. WHEN I ASKED MY PEERS FOR HELP THEY BASICALLY JUST SAID "HOW ARE YOU CONFUSED?" AND THIS VIDEO HERE HELPED ME IMMENSENLY. IT ALL MAKES SENSE. THANK YOU! THANK YOU! THANK YOU SUNNY!
This man is one of the greatest ever. I can confirm that I'm likely to pass my Computer Networks exam this coming Sunday.
You don't know the good you have done in taking time to explain this, may God bless you abundantly . Thank you.
you are welcome!
i about cried when he thanks us for watching and apologized for his chinglish accent what a sweet person!
Sunny, this was by far the best and easiest explanation I have had on subnetting. Thank you so much for doing this video.
Could not get my head around subnetting, however this method makes total logical sense. Wish I had found this method months ago!
After 7 years of banging my head against a wall with subnetting, your video finally made it click. I will take these Sunny Subnetting Table to my grave. THANK YOU!
Incredible explanation, I could not have accomplished my homework without this and you do it so well! Thank you Sunny!
Thanks Sunny!!! Clear, concise & comprehensive!😀
Sunny, I just finished the CCNA class and this is the simplest way to subnetting I have seen. Thank you SO MUCH for this video!! I'm looking forward to watching your other videos. Keep up the good work.
Thanks a lot for your nice comment. I will try my best.
lost of words to say.. I had a hard time in class today understanding this and here you are, completely making absolute sense... thank you so much.
You are welcome! I am happy as you could be able to find an alternative way.
wow you just made subnetting so FREAKING simple to understand. Holy thank you.
i am indeed speechless in the simple and explicit method you delivered your lecture.Thank you so much for making me have a deep understanding in Subnetting.
I hope you get all the good the world has to offer! This is an incredible video. I now understand subnetting. Before this video, I have taken courses and classes and none of them, despite being paid content, explained it as well as you did. Please do not feel your accent got in the way of this excellent material. If anything your accent was comforting, clear, and you did an outstanding job. Thank you!
