Hi Friends, I am Anshul Tiwari, and welcome to our youtube channel ITkFunde.
More about this video -
In this video, we will learn one of the most asked concepts of networking i.e. subnetting. Thank you subscribers for so many requests to make a video on this subject.
Subnetting is simple it's a method to subdivide your current network into multiple subnetworks so that you can utilize your network bandwidth efficiently.
This video is a perfect starting point for you if you want to learn about subnetting, subnet mask, CIDR range, network id, broadcast id. How subnetting really works and how you could create subnets on your own.
This video along with previous ones on the OSI model and IP addressing would build your strong fundamentals in networking.

@@ITkFunde why we need ipv4 for computer network when we get internet connection can get ip a dress then why we needs ipv4 class ?????

[@dilzak1]

Myself with absolutely no background of CS or IT based on the past four weeks of training for CCNA and this tutorial think that the IPv4 Subnet Mask allows a Local Area Network (LAN) to use its IP address most efficiently by dividing the maximum number of End Devices allowed (computers, lap tops, printers, cell phones, servers) into several sub networks without acquiring additional IP adresses for each sub netwrok. As he repeatedly said in this tutorial; do watch his IPv4 tutorial, I will definitely do that as well. Hope it somewhat answers your querry.

[@jah3882]

Good day! I got a question from 21:53 where you add the subnet mask of (I I 0 0 0 0 0 0) from the octet. Do you add the sum of the 8th and 7th bit which is 2^8 and 2^7 or do you add the least bit to the next which is 2^7 and 2^6? You explained that by adding both bits would result into getting the # of subnet mask. P.S. `Thanks for the lesson bro. Helps alot. This is just for me to clarify what I understood from the video. Hope you have a great day!`

[@ayanroy9820]

It's 2^7 & 2^6 coz, oct range ends 128. (Where 2^8 - 256) so, 2^7+2^6= 128+64= 192. New subnet mask. . I know it's super late reply but, I just learnt this 😅 and tried to explain. I hope it is correct.

[@edinetgrunhed6000]

finally i found explanation, not too fast not to slow just perfect, only have some doubt in @21:44 how he got 2 ^7 + 2^ 6 still not clear to me

[@subarnakarki9497]

Same problem

[@titu8878]

Each octet has 8 bits which ranges from 0 to 127 bits. So, if you count 8 bits in the power of 2 it will 2^0 + 2^1 + 2^2 + 2^3 + 2^4 + 2^5 + 2^6 + 2^7. As IPs are read from Left to Right, we have to take 2^7 + 2^6 = 128+64 = 192. Rest other 63 out of 255 bits in last octet will be assigned to host. I hope it helps.

[@johndebritto]

Thanks for the lesson. Going back to your analogy of Euro rail, if we have more hosts than what class C can provide, doesn't it make sense to convert some of the network to hosts to accommodate more hosts ? Converting host bits as network will not solve the problem, in my understanding. Please clarify.

[@ITkFunde]

Yes we borrow n/w bits to add more host, i have explained that in the later part of the video.

You are a super good instructor thank you. Just one thing I found confusing was how you set out the 8 bit values from left to right. I redid it from right to left like 128/64/32/16/8/4/2/1and it helped me immensely with my binary calculations and my bit calculations. Now when I add 3 bits I simply add the values to get my subnet mask of 224. Thank you very very much ! God Bless ! Victor
