Do you still suck at subnetting? I don’t think you do….but this problem might stump you. I need you to help me subnet my new coffee shops but the problem is a bit different than you are used to. I need you to subnet my coffee shops based on host requirements. How do you do that?

Sir can u plz make a vdo on ics and scada hacking basically on tools like ICSSPLOIT etc plz....
Hey Boss,
I'm from India and you inspire me a lot. I just wanna ask is there is any book or anything which I can read and understood the basic coding( for eg. MiTM attack sniff capture i know how it's work but I know the process of the sudo code that you write in terminal.)
Plz instruct me. Hope you solve my query!! And in future I wanna be like you one day
Thanks ❤️🙏

Raise your hand if you've been watching NetworkChuck for a long time🤚

If you really wanted to do this right, you would want 3 subnets per coffee house, one for your POS machines, one for your infrastructure, and one for the guest network. By my count, you would want at least a /29 for the POS network, and /28 for network/server/WAP, and a /27 for guest access. Reminder, this is per shop. ;)
This is where I would instead do Vlans for segmentation
@@Gruso57 same, but the point of the video was to subnet out the /24 that Chuck started us with, so I ran with it.
It's private IPs, we can be generous. We'd probably use /24 per subnet, so having a /22 per shop.
yes, it's called VLSM and most of the time POS and infrastructure can communicate so inter vlan routing and guest vlan is only allowed to internet, for which i would use /26 as you never know
@@autohmae Yes but the CCNA will always ask you these questions plus if you are working n a bigger network with point to point links you wouldn't want to necessarily give a /24 certainly if you are working with public IPs you'd want to use the minimum i.e. a /30 for point to point especially if you have multiple point to point networks.
It's truly amazing how you make important things so entertaining. It's like you're the super teacher that we never knew we needed.
Btw, I'm not even into this field, but I just love watching the fact you are so into teaching others. I'm just that guy at the back who will always protect the nerds. Bless brother
omg, it's just amazing. You are an amazing teacher. And I'm never going to learn this. You're so going to increase the beliefs of kids who are into this. Amazing job brother :)

I did my CCNA a long time ago in 2003 and even though have forgotten a good bit of the detail as I don't use it so much the IP addressing is the most I use these days in my daily role. You will often get questions like find the broadcast address or similar in the CCNA exam. One bit of advice for the exam is to write a similar table down before you start the timed exam to save a little time.
Just passed my Network+ Exam the other day. Writing out the bits and Nosferatu numbers saved me on the subnetting questions.
On the next few weeks i'm actually giving an exam on network protocols and it includes subnetting. You're a life savior 🙏
I'm Forty-eleven years old and I still subnet on my knuckles. Also days in a month. I enjoy the content. Thanks. Bit boundaries are the worst.
I haven't even watched the first subnetting tutorial in the series and I still got it. You teach stuff in such a simple and easy to learn way, even for complex stuff like subnetting
After finishing an Intro to Networking course at University, it's fun to see some real-world examples of subnetting and host/network reservation. Thanks for the fun and engaging video!
Great video Chuck! If anyone is still struggling with subnetting (I did when I first encountered this for my CCNA), I would recommend Wendell Odom's "IP Subnetting Beginning to Mastery" video. And yes, that is the same Mr. Odom that wrote the Official Cisco CCNA Study Guides. It goes from the absolute basics to what would be considered "mastery" for the CCNA (and covers a good bit for the CCNP). I hope that helps!
Im mentoring a group of students. They don`t gonna go for any networking sertification anytime soon, but they do need to understand it`s concepts in basics form and have some practical skills.
Your channel is one that i recommend the most for network-related questions.
Thank you very much for your work and content.
;-) You said the right words to make me feel comfortable with myself again. I am a generalist with 20+ years experience in IT and I am still not a specialist. The best magic word you said is RELEARN! Love your vids!
You are hands down one of the very best channels on TH-cam, can’t thank you enough for your videos!!!
First, I love the James Coffee Co. mug.
Second, I got the first challenge correct, but for the wrong reason, figuring that you had 3 coffee shops I went to the 4 on our Nosfera2 chart and figured we would need 2 bits from the host to the network, which ended up ok in this scenario, but would have really confused me on a Class A or Class B, so I'm glad to have the UpsideDown explanation of saving the host bits instead. That said, it became much easier to resolve the second challenge and I'm happy to say I managed to solve it on my own while you were paused.
Great playlist, awesome videos, thank you so much.
I love this channel man!❤❤
I'm getting some decorations now I'm in the car but later I will see another episode of this legend!🎉❤
i am watvhing this before my job interview... ill get back to you if I get the job. but honestly you are the best and the most easy to explain teacher I have ever seen
Back in the day (early 2000's) I hated subnetting so much, made a little C program to do it for me. It asked simple questions then told you want you needed to do, etc. It also showed its work, so you can double check it.
You're Welcome, Chuck! The most anticipated coffee break! ✅
Hey, Chuck, long-time sub here. I just want to take a moment to just say how much I appreciate the great work you're doing on your channel. I'm an old coder (30 years of C) so I've been around, but I always come back to your channel for a refresher. Like me, though, I'm sure you need (mental) breaks every now and again, so be sure to treat yourself right, too, okay? 😁👍
Network chuck is the best for new networking guys.... Super coffee Shop rocks...
Thank you so much! The Coursera course was testing me in subnets and I could not understand and you explained it so easily!
Glad to see actual networking content for a change.
I do not really watch the content in detail though. I do not want to pollute my knowledge about subnetting with the risk of actually getting confused about it. The way I do it works out great for me.
Hey networkchuck! 👋 Just watched your subnetting video, and I gotta say, your explanations are always on point. Your process for subnetting based on host requirements was easy to follow and understand. The use of binary conversion and the Nora Two chart really helped in visualizing the steps.
I appreciated how you emphasized the importance of practicing subnetting to become proficient at it. It's definitely a skill that requires repetition and hands-on experience.
One suggestion I have is to provide more examples and practice scenarios throughout the video. This would give viewers more opportunities to apply the concepts and reinforce their understanding.
Overall, your video was informative and engaging, and it definitely improved my subnetting skills. Keep up the great work, networkchuck! Looking forward to the next episode. 👍
Nice video, this is a good resource to consult every time when you need to work in network segmentation since this is not daily work so you probably, like me, forget some main concepts, thanks Chuck, and for sure networking+coffee is better!
Love the videos, you make learning the duller subjects fun. I have this weird wanting for coffee now tho... 🤔
This is the only channel that I dont skip the ads they're also fun.
This is the way to split up the public static IPv4 for their customers. Years ago I was assigned an static public IP and then a strange gateway and subnet. I had to look this up for the reasoning behind it. Pretty cool stuff!
Thanks for posting such high quality educational content. You make scary technical information fun and digestible.
Can you make a series where you go deeper into networking and network security? I feel i have a pretty good grasp on the fundamentals, but i want to get more of a deepdive into more advanced networking consepts. And i really like your teaching method
i wish my teacher would teached me like you do.
I got it in like 20 seconds.
For beginners its an awesome tutorial :D
I do some ethical hacking so im not specific to one software, OS or language. I watch these for inspiration and i am very thankful. You have helped me a lot. on subjects i already know sometimes a breakdown is just what i need to rethink. Ur an incredible teacher
do you do instagram hacks
for the last question the answer is D , I have an suggestion for you that make more video about practical side for networking , I see your channel missing this part , that make your channel growth , I Get that idea from this video the thumbnail interesting and the content also interesting , thank you Mr chuckCoffee
Thanks Chuck, be taking my Net+ in a month and be going for CCNA before end of the year.
I like so much the way you describe things 🙂Anything you present turns into entertainable stuff
I think I finally understand how to subnet. THANK YOU SIR 👍🏾
WOW! That subnet is incredible!
Great video on subnetting for a small business like a coffee shop! Dividing up the network into logical subnets is crucial to ensure efficient IP address allocation and proper segmentation. Nicely done! I'm sure this will be super helpful for small business owners looking to optimize their network infrastructure.
surprised myself by doing it completely correct with the video paused. didnt think i had it in me yet, thanks chuck!
Chuck, you're a helluva of a teacher! Greetings from Brazil!!!!
Sitting in a coffee shop ,drinking double shot ,watching Network Chuck..
I'm pretty much On Point right now .
PJ
Each coffe shop: 2x /64 subnets.
1 of those - wireless AP's and guests
Outher one - for employee / R. PI, server
Total: request /56 from ISP.
/60 or /48 of IP adresses are also possible.
Ipv6 only.
Fantastic Video! 😊 You are the best resource for helping to digest and understand some of the most interesting concepts on the planet. Thank you!
To be fair. I think an easier way of explaining it is to think about it, this way: Every bit you go to the right, you will half your hosts, and multiply the amount of subnets you get.
So if you got .00000000 that would be 256 hosts and move over one to the right so its .10000000, you get 128, wanna move one more? .11000000 damn you get 64.
You wonder how many subnets you end up with? Easy! Remember how many times you divided and multiply or raise to the power of number you divided.
So in the case where you get 256 you start with 1, divide it once, add the bit .10000000 you got 1x2 subnets (2) with 256%2 (128) hosts per subnet, do it again you get .11000000, 128%2 (64) hosts, 2x2 (4) subnets (each with 64 hosts).
Take it logically. This is how it works for me. BTW, I work in IT and had to learn subnets, it seemed hard, but after learning that the bits are just a translation and how everything ties in together, it only took me a couple of days to understand the process.
exactly.
/24 = 256-2 Hosts
/25 = 128-2
and so on. In the other direction i think of /23 = 2x/24 ....
This is lesson is pure gold.
Well explained! I just teach this to my students some week ago. Thanks for this Video!
Love these real world scenarios
I have not watched your videos in a long time and was excited that you were actually starting up a coffee shop and this will be here with discuss implementation of guest networks and VL ANS. Instead I was left scratching my head and asking what the heck is the Nosferatu method lol
Dude even when I’m sick you make me laugh.
i love your enthusiastic and fun approach to teaching; i'd also love to see Nosferat2 dressed in a little pink tutu, or alternatively, wearing purple robes and a mitre
Hey there, 👆🏾 leave me a message
Thanks for commenting 💚
Solution of the homework:
1).convert the ip into binary
=00110000.00011001.00011000.01000111
2).get the subnet mask into binary
As we have 21bits as network bits so the subnet mask in binary is 11111111.11111111.11111000
3). Find the network address
(Quick way) As the ip is 48.25.24.71 so the network address will be 48.25.24.0
4). Find the broadcast address
There are 11 host bits means 11bits are changeable and we all know that broadcast network has its bits set to 1
Therefore,00110000.00011001.00011000.00000(network address) into broadcast address is 00110000.00011001.00011111.11111111
= 48.25.31.255/27 answer
Easy:))
Been here for a long time, always love your videos. Thank you for teaching us in an entertaining way
Please make a video on communicating between different subnets and internet gateway and all that stuff...
Lol I get what you are doing but I would just give them each a /24 and call it a day lol then create a guest vlan and a vendor vlan.
I like every video that you made, it make me feel happy to learn more about computer network.
Thanks, i really enjoy all of your video in this playlist :)
Wow, so I went off at the end of your video and tried to teach myself reverse subnetting and it clicked for me.
Next video is going to use "reverse wildcards" for calculating the IP ranges of different IP classes. This suddenly just clicked a bunch of IP knowledge together.
Thanks Chuck!
If I did this right I do believe the answer is D.
Could you explain that? I am trying to understand how to reverse with the same method that chuck used
My way of subnetting is a little different from yours. But your video still help me better in subnetting.
Recently got my Network+ certification and was nice to know how easy it was for me to do this haha
Such a great refresher
Que genial!!!!....recordé todo lo que ya me había olvidado!!! Muy bien explicado!!!!
keep these videos up dude it helps so much thanks for the video
Chuck, AKA Bernard Hackwell, Great job. Thank you!!!
Thank you, This was AMAZING.
It's always a happy day when Nosforatu returns..
I love you man, thank you so much for your great efforts, I have pasted my Sisco class with A, thank you,
Aww maaan, I like this guy, That's so bad that youtube doesn't recommand this channel anymore, I really like the explaitions in the videos
👆Congratulations you won a prize🎉🎉
Yesssss CCNA content again !
Loved the series and the knowledge. But I was waiting to see how it is applied in real life.
I love your content Chuck, thanks for inspire !! Im from Mexico
I would be happy to be the network administrator of your coffee shop when you decide to open one here!!!
Dude!!! I was just studying for my net+ and was reading about subnets
Wow.
I respect the teaching method.
Already CCNA (to the main part because of Networkchuck and Jeremy), working as a Systems Engineer, doing subnetting all the time still watching a video about learn to subnet just because NETWORKCHUCKS AMAZING CONTENT! 🥳🥳
All the best to the ppl working on their career and CERTs!
Can you give me some tips? I am learning networking in CCNA courses and trying to study for CCNA. I am also looking for internship on network admin or systems engr too so if you can help me, i would appreciate it a lot!
Chuck never stops talking, even during the coffee breaks🙃
Love your channel, man. I just turned 30. I should really make an effort to learn more about networking and security.
The CCNA series back? I have been waiting for it🤩.
You made me love networking man
Great and clear tutorial
Great course I really appreciate it
PS: saying borrow the host bits sounds more common sense than saying hack the host bits.
Waiting for the next episode ❤
That must impress at least half as many people as the manbun does at your coffee shop.
in VN, teachers teach us so suck, you know, after watching this then i say OMG, that is amazing it 's easy bro
Thank you for the educational video! 😇😇
Completely new to this channel and while I have no idea what's going on imma enjoy the vidja with the tacos I made, cheers!
Great video.
I'm DCAing in R25VRs as well. ETH heavier DCA and ALGO. I'm taking your advice and starting Google tomorrow with a 50 dollar purchase and continuing Microsoft and Apple. VTI and VOO on another app and longterm portfolio. Here we go family!
2:52 that picture 😆🧛
Great chuck, keep it up 👍🏻
The coffee break ad😂
There's an easier way I used.
Just use the 2^n-1 formula and equate it to the number of hosts needed per network and round off the resulting decimal number to it's next integer value which gives us same number of host bits we need to manipulate.
13:30 Come back every year.... Yep. sitting here at work rebuilding our wireless network and wanted to double check I got things correct. This is a perishable skill if you don't use it a lot.
Got them all right 😄 the question in the end is easy to solve 😌
whats the answer?
2 days ago I had my (sort of) A-Levels from networking and the question I picked was about IPs and subnetting. Needless to say, it was a breeze with the "You suck at subnetting" series so thank you :)
(fun fact: one of the questions was also to find a subnet mask with 30 hosts)
I never deploy subnets lower than 254 host. I just follow the format 10...0/24
And if you have customers connected to your infrastructure who just need to access one of your servers from i.e. 5 of their servers. It is a huge waste of IPs to then not use /29 for their encryption domain (in case of ipsec vpn) or mpls connection.
Thanks !!
Good teacher, but when it's private IPs, in the real world, we'll use /24 per subnet, as someone else commented, probably want multiple subnets per shop, so probably allocate /22 per shop.
I might have chopped the clients into a different subnet/vlan to keep them from poking at the employee/business servers.
But, I get new guys with no networking experience all the time. Your videos are really good, though, and I might point them your way to help get them up to speed.
Hello NetworkChuck I was wondering if you could tell me what software you are using for the little drawings because if I explain things to my fellow classmates they often tell me that I'm too fast and stuff so I can make the tutorials better for them. Have a nice day :)
ty
Networking is new to me. I watched and was confused but NetworkChuck makes it look so interesting that I want to learn it. A great teacher instills a hunger and desire to learn in people.
Huge Respect Sir 🧑🎓🤝
