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

Professor Sunny is a national treasure. A patron saint of Network engineers.
absolutely agree with that
Saint Sunny*
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
tfw when you pay 10k a semester for school and a free TH-cam 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 TH-camrs! 😀
@@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
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😢
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 ..
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?
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 :)
This is so much easier to understand than looking at a CIDR notation chart. Thank you for this!
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!
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.
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 ☀️
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.
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.
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 ?
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.
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!
What if the subnet mask is 23 or less@@sunnyclassroom24
Your "Chinglish" is epic. Thanks for helping me understand this, you're a true hero.
Got that from Black Lagoon?

@@Laevatei1nn lmao
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.
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).
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
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
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!
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.
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.
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
I have been getting so confused, frustrated, felt stupid and ultimately discouraged that I just couldn't get this and would never understand it. I am not very good at multiplication and math in general. I almost cried when you went through this, it finally makes sense. I still kind of want to cry now. Thank you so much for everything. I feel like something just turned on and I understand it now.
Your 13 minute video is more clear than 13 hours of lectures. Thank you!
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) !
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 ??
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.
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!
my heart is literally crying out of gratefulness, that teachers like you exist. God bless😭💛
This dude just blew all the subnetting guru out the water with this basic format.
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!!!
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 ✨✨
This was extremely helpful and far more simple than the others way I've learned. THANK YOU
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...
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
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.
You should get an award. Thank you for making this UNDERSTANDABLE! 🤯🤯
Just reiterating what everybody said below! Managed to do my first subnetting just after watching this! You are a legend and your English is better than who's a native speaker and doesn't know how to use it to deliver the concept! Thank you so much!
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
One of the best explanation of subnetting and I have been teaching it for 3 years.
thanks. we are colleagues, then.
After spending an hour looking at subnetting videos I can say this is by far the best explanation, thank you!
Sunny, I am on my 3rd year attending a Private University for a BS in Cybersecurity. Have had multiple classes on sub-netting and nothing has been as clear cut and SIMPLE as your discussion. THANK YOU for your ease and clarity my friend!! I hit the SUBSCRIBE button immediately.
sounds like that BS is bs
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
@@crazychroniclez Haha - there's a typo too. The first "you" should be "I".
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!!!
Thank You Mr. Sunny for the very clear explanation of Subnetting. I used to avoid this topic but now I am confident enough to subnet my own Home Network. Thank You once again.
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 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!
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.
Sunny, thanks for breaking this down brother. I clearly understood the whole process on the first time watching this video. Honestly, you explain it better than some of the more popular Net + instructors.
Great to hear!
Agreed
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!
I owe my life to the sunny table
the best video on subnetting so far , thank you sunny
Your video on subnetting the best have seen so far. Great job!
Many thanks!
This man is one of the greatest ever. I can confirm that I'm likely to pass my Computer Networks exam this coming Sunday.
Could not get my head around subnetting, however this method makes total logical sense. Wish I had found this method months ago!
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.
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.
the best teacher ever , R & S is now fun with sunny , who agrees ?
thanks a lot.
I do, it helps quiet a lot
i studied this about to 2 months and i didn't get it but you did it in only 10 mins guy u so talented keep working hard we are with you
Your teaching is brilliant and clear. Your accent isn’t a problem at all. Thank you!
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.
Thank you so much for this. To be honest this is probably the simplest and cleanest explanation/expression of subnetting. I totally needed this. I transitioned to IT from legal. Currently in a IT role and I'm looking to move up within my company. I am studying for the Google IT Support certificate to help me prepare for the Comptia A+ cert.
I'd say go straight for the A+ or Net+. I have never seen the Google IT cert being mentioned in job applications. The ITIL, maybe, but even then you can go straight for the A+ or Net+.
Thank you Sunny. Seriously, this has been an eye opener for me. Your style of teaching is incredible.
you are welcome! Thank you very much for your compliment and encouragement, which makes me very happy :)
Why is everyone else so vague about this? Finally, someone to explained it straight forward. THANK YOU!
Excellent video Mr. Sunny. I understood you just fine. I've learned to listen closely to all my non-english teachers and find you adjust your hearing.
And in some way more pleasant and in a paradoxal concept one focuses more😉
I came here in 2023 looking for a simpler explanation to subnetting than my Network+ N10-008 book provided. It was converting everything to binary (which I won't deny as a useful skill to have) but as someone just learning the concept, my brain was fried. This was VERY helpful and I copied the subnet table for my notes. You've earned a subscriber!
I remember struggling with this 20 years ago while working on my CCNA/CCNP at a Cisco college, and this video makes it much simpler. Thank you.
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
That is the clearest way I have ever seen to explain subnetting, thank you! Now people can go on the binary part of subnetting to get to the why of the 255 after having understood the basic concept!! LoL
Thank you for watching!
I learned more from this 13.32 minute video than my whole semester
The accent of an angel! I was struggling eith this you just save my life.
It took me 3 yrs of my telecoms course course and stil failed to understand it but now in 13 mins im wondering where the problem was. This is so simplified thanks you so much Sir👏🏽👏🏽👏🏽👏🏽
Great teacher, bridges ALL my learning gaps.
You are a complete lifesaver. Thank you for breaking this down in a way that is easy to understand. My networking professor explains this in a way that makes my head spin. I feel so much more confident after watching this video :)
Me too! My professor had us watch some other guy on TH-cam and I Honestly started getting dizzy! :-/
Literally a life saver ! I was so confused in my class but this definitely helped me understand the concept of subnetting. Also no need to apologize for having an accent Sunny ! It did not in any way hinder my learning when watching this video :) Thank you again ! I'll be on this channel often.
Thank you for supporting!
This is probably the single best explanation on subnetting I have ever watched. Thank you so much for this.
You are a legend Sunny,
i just found out that my Teacher was just making a mess in my mind instead of making it simple, i thought i was the one who can't get it.
thank you
it is a complicated topic. All textbooks I read use the bit by bit way.
I thought I would never be able to subnet, but everything is clearer now. You've got respects from Mexico
I am happy for you.
This was so simple to understand as I’m studying for my CCENT. Thank You!
THANK YOU VERY MUCH, THIS EXXPLANATION IS SO GOOD, I LOVE SUNNY SUBNETTING TABLE.
Great job at simplifying subnetting, I wish I would have found this years ago as it would have made things so much easier to understand. I'll have to check out your other videos as I take my networking course next semester and try to get a couple certifications that will no doubt include subnetting. Thank you!
your chinglish accent really helps me, simple yet easy to remember and understand :) ... thank you Sunny
Thanks a lot and you are kind.

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
Oh my gosh - after watching this video, it was like my whole eyes had been opened up to the world!!!!
Thank you for your time! I am glad you found my videos!
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!
Wow. Just wow. I've been struggling to learn this for so long. You taught me how to do it in under 15 minutes. WOW!
I am glad it helps.
I've looked at a ton of different videos that explained subnetting and no one did a better job than this one. Pretty incredible
Excellent...
I enjoyed the " Chinglish " joke - very humorous.... However I think your English is very good because of your slow and steady speaking voice. THANK YOU.
you are welcome!
This lesson was SO helpful in getting me to finally understand how to calculate sunetting. Thank you, Sunny!!!!
Do you think professors and textbooks over complicate this to make us feel bad? This guy is like "bare with me because this is longer than most of my videos" meanwhile, it's 13 minutes and covers everything better than hours of classroom time.
This is by far the simplest most intuitive subnetting approach on youtube! Thank you sir!
This video is just amazing... so simple. My IT teacher should be jealous. Thank you for the videos i love watching them.
ALWAYS TO THE POINT... just amazing!!
Keep up the great work! 😁😁
You're very welcome!
Loving the chinglish accent, it's all good. Thank you for the breakdown, I was somewhat lost for some time.
Glad I could help!
