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?

@nicko9715 Год назад

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. ;)

@Gruso57 Год назад

This is where I would instead do Vlans for segmentation

@nicko9715 Год назад

@@Gruso57 same, but the point of the video was to subnet out the /24 that Chuck started us with, so I ran with it.

@autohmae Год назад

It's private IPs, we can be generous. We'd probably use /24 per subnet, so having a /22 per shop.

@tvojejbabkydedko Год назад

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

@davidsomething4867 Год назад

@@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.

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.

@FINANCEFREEDOM007 2 месяца назад

14:17 the answer is D (48.25.31.255) with the subnet mask of 255.255.248.0

@timecubed Год назад

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

@Xlefty69 3 месяца назад

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:))

@laur.an01 Год назад

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.

@insideout114 Год назад

exactly. /24 = 256-2 Hosts /25 = 128-2 and so on. In the other direction i think of /23 = 2x/24 ....

@K2_Chris Год назад

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.

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!

@ITAcute-ve3vp 5 месяцев назад

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.

@firstwolfplus Год назад

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.

@TechDaddyProxy Год назад

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.

@sheenismhaellim2215 Год назад

@insideout114 Год назад

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.

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. 👍

@tonyagee3277 Месяц назад

I've seen some bad trainings and some good ones. This series is the best I have found. I know this to be true because after watching previous video in the subnetting series on how to subnet to get X amount of networks, I knew before the teaching how to get X amount of hosts. This is a hack I have figured out and everything is based on 256. If you need 64 hosts you will only be able to subnet 4 networks. Need 4 networks you will have 64 hosts. You can play with all the numbers in the binary chart and they will work out. Subnetting on class C conquered. Now I have to figure out A and B.

@aaronjohnson8715 Год назад

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.
