VLSM subnetting - CompTIA Network + Simulation Question & Solution

[@estebanchaves8865]

My man sunny, thank you for your videos. I've been studying cybersecurity for a while and your videos were helpful, I could get a job, keep it up man.

[@sunnyclassroom24]

Thanks a lot. I will upload more.

[@reconstructedrichard208]

thank you so much for making this dude! I'm taking my network+ exam tomorrow and pass or fail, you have certainly raised my odds of success

[@bstanis1237]

Great work CompTIA Network + . All the best for you Eng.Sunny.

[@sunnyclassroom24]

Thank you!

[@dinorossi6611]

Your subnetting videos are the best. I think that Jacob Hess is using your technique which is great. Thank you Sunny. Sunny days are upon us.

[@sunnyclassroom24]

thank you for coming back!

[@jorgemontero384]

You are helping me on studies for CCNA thank you so much Sunny, please continue uploading videos.

[@mrse7en196]

Big fan of your work, Sunny. Hope you guys are doing well in the christ of coronavirus

[@sunnyclassroom24]

thank you!

[@suzannebrandt1065]

Your jokes are funny lol keeps me engaged and paying attention. I use your sunny table for everything thank you 🙏

[@sunnyclassroom24]

Awesome! Thank you!

[@GiggleYohoo]

I kept in browsing to look for this chart on KZbin until I found this again in your channel and its magic. Your accent is funny but I love it seriously. Keep it up Mr Sunny. I Bookmarked it already and clicked subscribe. You're the man. Haha

Thank you very much Sunny your videos help me to get my Network+ certificate. You're the best !

[@sunnyclassroom24]

Thanks a lot!

[@RynAmelli84]

Wow this is much simpler. This should definitely assist me in my upcoming Net+ exam. I'm absolutely gonna use it. Thanks so much Sunny!

[@zero_day_xsploit]

your the best on youtube do security on udemy ill support ... after ur subnet video i can do it in my head .. incredible

[@sunnyclassroom24]

awesome. Cheers......

[@leeds85]

2:43 Do you have to commit to memory the sunny subnet table to answer these questions in the Network+ exam. Looking at exam rules it doesn't look like you are allowed to make notes or calculations other than writing materials provided. How does this work when taking the online test?

[@kalleshlavanya8570]

Sub-netting made very easy, Thanks for your efforts.

[@saeli.49]

Easy and simple to understand! Thank you very much for sharing your knowledge in such a didactic and pleasant way.

[@JuanMoreTrade]

Thank you for your excellent work ! Wish I could buy you a beer for the clear explanation.

[@saleemkhokhar3458]

I know I'm late but thank you!! this is easy all because of your style

[@surndrabudania1]

Great Job Sir!!! Huge fan. May you always be happy and keep spreading this knowledge. One suggestion Sir. Playlist can be better organized.

[@sunnyclassroom24]

Thank you!

Grande Sunny!!! Spiegazione perfetta. 😁👍

Thank you ! 😁👍

[@ryannmars4918]

Hi Sunny! I just watched this video and I have a question for the last part asking “Which of the following would represent the LARGEST possible contiguous block of the remaining address” You took the total USED and subtracted it from the total AVAILABLE leaving only the remaining amount of 16. But that isn’t contiguous is it? I thought the answer would be /25 for the Sales department because they needed 100 hosts and the that subnet allocated 128 hosts leaving 28 contiguous unused. What am I missing? Thank you!!

[@BreakpointFun]

6:48 it connects 5 new devices to setup No more ip's What's the point use /24 for everything

[@baldovincadenamejia244]

Hi Sunny great video as always! In the example we are told the network ID range is 172.30.232.0/24. You explained in this video that we use one subnetting table or the other depending on the subnet mask (e.g. /16 subnetting not the same as /24 subnetting). But how is it determined that a /24 mask is used for the network ID range? Why not 172.30.232.0/16 or 172.30.232.0/8? Also I was read in an article that, for subnetting, it is possible to borrow one bit from the network in case you need more subnets than the ones one can make with the given subnet. How is this done? Is there any limitation to this? Thank you in advance.

[@seif-eddinesegueni548]

hey i have a question, they gave me this 172.19.160.0 /22 and I'm confuse which table i can use =,can someone help me please :/?

[@hajarsalman35]

Hi Sunny I would like to thank you about the wonderfull explaination of subentting and I would like to ask about what does this question means "which of the following would represent the largest possible contiguous block of remaining addresses" because I didn't get it and how you solved it

[@NetworkingNewbies]

Impressed by you, I also started, just a try by me.

[@sunnyclassroom24]

Thank you for watching! Check out my other videos please!

[@chrysndedigwe2569]

Very easy by your method. Thanks

[@jerchinn]

I need to subnet with CIDR as /21 in AWS ? How to do that ? This table does not help me. Please advice.

[@Richie3948]

CIDR 21 subnet mask is 255.255.248.0.

[@NavidDariya]

Good job ... I like and suggest ur videos ...

[@sunnyclassroom24]

Thanks.

[@madhumithaselvam3264]

what about for 10,000 workers? Company ABC has 10000 workstations in their head office and the IT manager would like to assign a subnetwork address for each department. The IT manager wants to create 9 subnets using the 192.168.0.0/18 block and assign the first subnetwork to their servers and the rest for their 10000 workstations. How will we compute the subnetwork requirement? List the subnet address with mask for each subnet.

[@farshidkeshaninobari5336]

Dear Sunny thank you for your usefull tutorial, really simple and practical, thank you. I need to learn to how to calculate(find )network address and ANDing. Do you have any videos on these subjects?

[@fercoshow]

So for Net+ exam do I need to memorize this table?

[@badrhani6390]

Dear Sunny, thank you for your videos I have learned a lot of them. It would be nice if you could make an order of how to learn networking specially for beginners. Starting with a basic suite then for each subject a separate suite. thank you very much

[@joemarvelproductions8592]

Love the chart you have. Could you theoretically extend this chart to include subnets "smaller" than /24 (example- /18)? For a 10.10.0.0/16 network the chart would have max value of 512 instead of 256. Anyways love the videos!

[@anjilkhadka7387]

where can i get this CIDR notation Simulator

[@Richie3948]

Well explained - thanks!

[@Vadinaka]

Hi Sunny, I am a retired ex pilot who is teaching himself IT. Your courses are a gift from heaven, however, I could use some help. If you were to start, in which order would you watch your videos? I would like to build a lab while securing my home network with IoT devices. Thanks and keep up the good work.

[@sunnyclassroom24]

Hey, Jean, Thanks a lot for your nice words and encouragement. I published my videos, not in any order. However, I have organized them by playlists. If you can click my playlists and choose one topic as the major theme. For example, the playlist " 1 OSI Model and related" is the foundation for all networking and cybersecurity. And then move to the second playlist: 2 Topology, cabling and cabling structure". At this point, I have not finished all the videos to cover all topics. Thank you very much for your support and interest.

Hello sunny i don't understand how u solved the question. I mean you have only 254 valid hosts. So u can use /26 which gives you 4 Subnetts each 62 valid hosts but Sales department wants 100 valid hosts??? How can u use /25, /26 , /27, /28??? You have only 254 valid hosts in this 172.30.232.0/24?? Is it like this A)/25 First sales Department gets 126 valid hosts. So i have only 126 halid hosts left how should i devide for 3 departments??

[@addanametocontinue]

That's the point of using VLSM (variable length subnetting mask). You don't divide the available hosts into equal parts. You assign only what is needed. See below for an example of how I assigned mine out: HR = 57 172.30.232.0/26 Sales = 100 172.30.232.64/25 IT = 12 172.30.232.128/28 Finance = 25 172.30.232.144/27

You should allow translations.

thanks a lot. I have no idea of this function. I might try it for fun.

What if the company asks you to provide 512 devices?? Edit: found your class B subnetting video! Thanks Sunny!
