Subnetting Simplified for Beginners | Network+ | N10-008

[@samsmit8245]

wow you weren't kidding when you simplified. I think this might very well make sense for even people with no math background, well done like usual

[@BurningIceTech]

Haha yeah well I tried

[@ugookorie3863]

I have never learned subnetting the way you thought it. You couldn't have thought it any better. I have watched this video and I am watching it over and over again until it sinks in very well. Thank you for breaking this down to a 6-year-old. 😊

[@Sabrina-xq3gq]

If this is your first time learning subnetting, you may be confused but if you have been bombarded with many confusing formulas before watching this, you will understand that this is the simplest method to understand. Good job. I will sponsor you when I become a network engineer.

[@CrowdControlCC]

I am watching this playlist as a refresher from what I learned in school. I noticed that you said that you decided the last octet in the subnet mask by subtracting the amount of IP addresses in the subnet you want to make. I feel like you should have mentioned how you actually get the last octet: taking bits from the last octet and making them network bits instead of host bits. I get this is a beginner video, but that bit (pun intended) of information helps the person learn why the last octet is the way that it is and increases their depth of understanding.

Would you put the full chart on here for class A,B,and C?

[@Prayzrmuzic]

Good job breaking that down. Thanks

[@aidanquigley3351]

Thanks mate very helpful :)

[@HawksDiesel]

Clear and simple. Thank you for taking the time to put this together

[@BurningIceTech]

Most welcome sir

[@jeffreymagsoa2884]

Nice, short and straight to the point. Just the way I like it

[@navfam4610]

ABSOLUTELY need to commit your chart to memory as I prep for my Net+ exam in the coming months...you really did "simplify" this and I am thankful!!

[@candicebremming940]

love the way you explained it

[@jr_dev-xg2xo]

Explaining how to use/memorize the subnetting chart was so helpful!!

[@thomasmaguire8615]

What about the cidr numbers under 24?

[@beatzbyjay24]

Thank you so much i am watching your entire course im up to lesson 12 so far already subscribed

[@devinnpierre]

Man!! This made so much sense and Im glad ive subscribed to your channel.I failed my exam the first time and im using this to help me better understand how to accomplish this knowledge and its sticking

[@BurningIceTech]

Best of luck with the next round Devinn. If you need more clarity on a specific topic feel free to ask away :)

[@davidarmstrong3664]

Love you funky town

[@Jude-b4z]

Nice work! Thank you very much for this lecture. You have simplified subnetting in a clear and understandable language. Could you please add the "Number of Hosts" column to the cheat sheet?

[@PinoyDiskubreChannel]

life saver 😍😍😍😍

[@samboyd9707]

Hi there been following you from a while, thankyou for explaining the concept and makes it easier.. if its possible can you please make one more video with class B IP if you can? i'm struggling with it.. thankyou..

[@richharms77]

Thank you, this is extremely helpful. For some reason, some parts of subnetting is just not clicking for me. I feel like maybe I'm starting to understand, and then i feel confused all over again. I have two questions that might help me to understand this a bit more, if you would be so kind. First, and hopefully not too dumb of a question: How/what does the CIDR notation tell me about the subnet mask or IP address? This is something I can't seem to wrap my head around. Right now, it seems like the CIDR is just randomly assigned, and I know that isn't correct. Second: in the Finance and Sales department examples, you show that they have essentially the same IP address all the way up until the last octet. In my head, I'm thinking that the 3rd octet would have to be different somehow, to denote they are on different networks. I understand that they have been subnetted with the division in the last octet for the first dept ending in 127, and the second dept starting with 128. I'm having difficulty understanding how those networks would not see each other.

[@Staderri]

Subnet meaning subdividing a network into many networks which has many practical applications The IP Address and subnet mask pair defines the network or subnet a device (host) is apart of. Think of CIDR Block notation as just a shorthand way of representing this information. It does have other applications such as supernetting that collapses multiple routing entries into a single entry but that is outside the scope of this video. With the department subnets, a more accurate representation would also include the subnet mask to show that though the IP addressing scheme still spans from 1 through 254 it is further divided into multiple networks. So the 254 addresses can be in one network, split down the middle into two or further subdivided to every four IP addresses in the range starting a new network. Hope this helps.

[@cyberghost_01]

This table works If its a.subnetting classe C Networks, but what if a classe A subnet questio

[@BurningIceTech]

The table actually extends all the way to Class A so the full one includes all the classes. Generally you're only going to get questions about Class C in the N+ exam but it won't hurt to know the other classes as well. If you'd like the full table let me know then we'll make a plan to get it to you

[@steve5nash]

why does the CIDR start from 24 and goes up to 30? Those seems pretty random number.

[@olebogengdiemeng9647]

Good Day Sir, Can you kindly make videos about Server + (SK0-004)...

[@BurningIceTech]

The SK0-004 was launched in 2015 and is very old so I don't think anyone will be making anything on that any time soon. The new replacement SK0-005 was launched in May 2021 so you'll be better of doing the newer version of the course :) I'll eventually cover the SK0-005 when I finish Network+ :) working on to many other courses at this exact moment but I'll eventually cover the Server+

[@olebogengdiemeng9647]

@@BurningIceTech Thank you very much for your prompt response. Your videos makes it easier for one to understand and be more practical and well versed in theory.. Keep the Ice Burning

[@GordonVanHorn]

19:50 for the sales department why do we start at 129 instead of 127 or 128?

[@user-pt2ux8np3o]

Those two are reserved.. end of the first network and the start of the second network.

[@PS2Damon]

are the answers going to be as simple as "what is the amount of IPs in a /30 cidr" I doubt it will be that easy

[@whenpigsfly3271]

I get the theory. But how come NOBODY will ever show a router dashboard and demonstrate how subnetting is actually implemented?

[@JakeFromKushFarm]

Took me 2 hours to watch this 30 min video

[@rohanbhalerao7417]

shouldn't it be 0(1-255)256 ? at 12:34

[@rohanbhalerao7417]

sorry my bad, considering 0 as well 😅

[@BurningIceTech]

@@rohanbhalerao7417 Yip :) you start from 0 and end at 255. It's good that you ask though because that's how you learn. It also means your paying attention. Well done

No ​@@BurningIceTechit means you're putting out faulty videos. You should redo this and please try not to giggle over black space.

How did 192 become 64

[@BurningIceTech]

If your referring to the 192 as in 255.255.255.192 then that would 256 minus 64 which gives you 192. Not sure if that answer's your question or are you talking about the more technical side of things as in bits used and borrowed ect? If you provide me with more info then I'll be able to give you a better answer :)
