Class B ID - Subnetting

Subnetting playlist include 5 examples of subnetting.
• subnetting is simple
1. Subnetting is Simple
2. Subnetting a subnet - Sunny way
3. Class B ID subnetting
4. VLSM subnetting - CompTIA Network + Simulation Question & Solution
5. VLSM Subnetting - subnetting a subnet
Example 1
Suppose I have a class B ID: 172.16.0.0/16,
and I want to create 4 new subnets.
Here are three questions I am going to answer:
1) What is the new subnet mask?
2) How many usable host IDs for each new subnet?
3) List each network ID, the useable host ID range, and broadcast ID.
Example 2
Given the same ID: 172.16.0.0/16, we want to create 1000 subnets. Here are three questions to answer:
1. What is the new subnet mask?
2. How many useable host IDs are there for each subnet?
3. What is each new network ID, its host range, and its broadcast ID.

As so many have said, your accent is an asset, not a hinderance. It helps me stay focused and learn what you are saying THE FIRST TIME, because the cadence is not standard American, and I do not start daydreaming while you are talking because my brain is actively engaging with your accent.

[@sunnyclassroom24]

Thanks you for watching! I appreciate.

[@nithishkumar7792]

Exactly 💯💯. I agree with this.

[@jerrantys]

It helps a lot too that he speaks so slowly and enunciates and emphasizes the most important parts. This guy has made more of concepts click for me than any other teacher has.

[@vacumecleaner]

That is so true

[@yeshua5978]

@Sunny Classroom excuse my ignorance I'm new to this I was just wondering where do you get the 256 to divided it by 16384? are we always have to used that number 256 or they might be another numbers ?

[@Don-Carillo]

6 Networking teachers have disliked this video because it takes them months to teach what Sunny does in minutes. 😂

[@sunnyclassroom24]

I like your humors.

[@denverlilly3669]

I read through an entire elaborate pdf our professor provided for us and I couldn't understand it. He simplified all of that in 1 video lol.

[@connief2679]

Dearest Sunny, no need to apologize for your accent. You are an excellent teacher. We were reviewing subnetting in class today to prepare for our final exams, and I was so confused and frustrated! I watched your subnetting playlist when I got home and it is so clear now! Thank you so much!!

[@xbadandy182x]

I am 14 years in to my IT career and you are easily the best teacher I've come across in terms of subnetting. Thank you so much!

[@abubakarmabdow]

Honestly, I am CCNP certified and I learned Subnetting in hard way. I wished if I watched this video before. Thank you so much

[@southproduct7463]

What method did you use for your exam?

[@brstreet9950]

Instead of taking networking in college, I should have just watched these videos. You have a talent for making this understandable.

[@strawberrymilk3352]

[@impatconrad]

Hello Mr. Sunny! First, your Chinglish is great and I can't imagine what I would sound like if I tried to speak Chinese, so my hat is off to you sir! Thanks for your very patient explanations...this has been most helpful! Please be safe and well.

[@vonni508]

PLEASE never apologize for your beautiful accent. We all can understand you very well! Thank you so much for your clear instructions.

[@greatminds1939]

I cannot thank you enough Sunny for all the lessons. Am becoming an expert just by watching your videos. Thanks a lot.

Sunny you made it easy to do subnetting. You speak well. No need to self deprecate. These tutorials are great. You break down complexity and make it easy to understand quickly.

[@reunionreunion2386]

Your explanations are fantastic. I learned more in 30 minutes than in 4 weeks in a Network+ class. May you experience the joy you bring others!

Sunny you are amazing. I am embarking on an additional career, and with my new classes, I always look for your tutorials to help me understand what my teachers/courses seem to make so difficult. You break things down into such manageable pieces in a clear and concise fashion. You have lit that lightbulb above my head on more than one occasion and I thank you for that. Your work is truly valued and appreciated. Thank you for all your hard work and your great attitude. I always look for one of your videos if I have an issue. Please continue creating them. 😁

Please stop apologizing for your Chinglish. You are well spoken, deliberate, and speak in a regular cadence. You provide the most clear explanations on youtube for non trivial subjects. I probably watch 3 or 4 of your videos a week. I think of you as the indomitable Sunny and look for your videos if I need to understand something. Your accent has never been a barrier to the incredibly crystal explanations you provide.

Mr Sunny, you are just amazing teacher. Very nice and clear explanations and your English is really good and very understandable so you do not have to worry. I will definitely recommend you to all my classmates at Uni. Thank you! Greetings from Slovakia.

Thank you for doing these videos. You take the time to explain how to do subnetting without being in such a rush, and that helps a lot. Your videos have been the most helpful of anyone, by far. At one point I thought I was lost until at the end of this video, you explained why a /26 can have 1024 subnets. (because the given CIDR value dictates which table to use.) Thank you so much; I have an exam coming up that will have a lot of subnetting in it, and your videos have helped me become much more fluent. Your "Chinglish" is very understandable!

[@GuardianApe]

Who needs meditation when he can listen to your voice explaining class B subnetting? Thank you for making these videos , you're a rare gem. I've got a question though, how can you tell when to divide by 256? Can you tell me in what circumstances I need to divide by 256? Because I noticed you didn't do any division in the second example.

[@sunnyclassroom24]

every 256 in the 4th octet is 1 in the third octet. Thus, if the number of hosts is more than 256 you need to divide by 256. If the maximum number of hosts in any subnet is less than 256, do not use division.
