Subnetting a subnet --sunny way

Subnetting playlist includes 5 examples of subnetting.
• subnetting is simple
1. Subnetting is Simple
2. Subnetting a subnet - Sunny way
3. Class B ID subnetting
4. VLSM subnetting - CompTIA Network + Simulation Question & Solution
5. VLSM Subnetting - subnetting a subnet
Subnetting a subnet is similar to subnetting. Compared to subnetting, subnetting a subnet takes only one more step to find the column we need in the Sunny table. Once we identify the column, the rest of the subnetting process is exactly the same.
The example used in the video.
You are given a single network ID 125.23.200.64/26, and you are asked to set up three separate subnets for 3 different departments sharing a building. Your task is to list each new subnet’s network ID, new subnet mask, Host ID Range, # of usable host IDs, and Broadcast ID.
Practice question:
You are given a single network ID 125.23.200.128/25, and you are asked to set up three separate subnets for 3 different departments. Your task is to list each new subnet’s network ID, new subnet mask, Host ID Range, # of usable host IDs, and Broadcast ID.
Answer for your reference (you can choose three out of four subnets. One is wasted.)
#1: 125.23.200.128/27, 129 - 158, 30, 125.23.200.159
#2: 125.23.200.160/27, 161 - 190, 30, 125.23.200.191
#3: 125.23.200.192/27, 193- 222, 30, 125.23.200.223
#4: 125.23.200.224/27, 225 - 254, 30, 125.23.200.255

[@sunnyclassroom24]

Glad it helped!

[@tuworlds]

one of the easiest way to resolve subnetting. i wish i knew this 10 years ago... I learnt this the hard way back then. thanks sunny

[@safariliberateur5264]

Man, this Mr. knows his network. Kudos for real.👏

[@lukelance540]

Subnetting a subnet that goes into another subnet makes for a subnetted subnet. I loved the video you saved me.

Thank you so much for your help. I gave up on my Cisco CCNA 01 practical test/EXAM yesterday Friday because I wasn't sure about my knowledge and now I have confidence to go try again. Am from Namibia, thank you so much!!!

[@sunnyclassroom24]

You are welcome! I know CCNA has a lot of things to know and many are tedious and boring but do not give up easily. Once you know some basics and you will find it interesting and computers communicate with each other just like people and many protocols are made just like those in our daily life.

[@hassanbashiru3507]

Hello Sunny, I'd like to thank you for your amazing videos. I have a question as regards the Sunny table, what determines the figures in the subnet mask column? Is it the subnet mask of the network ID given? Or is it /24 - /32 for all scenarios.

[@ktacyberlab4484]

Hi Sunny, Thanks so much for explaining the subnet and subnetting a subnet in simple terms. I have one question with "subnetting a subnet" topic. How did you come up with the number 16 when you further subnetted between 64 and 128? From 64 to 80 to 96 then 112. How did you come up with the number 16? Please advise. Thank you!

[@TonyKoji]

I was a little confused at first as to how you got to subnet 16. I had to watch that part a couple of times but I finally got it. Thanks again for helping!

[@umeshfernando3438]

Great Teaching, really clear now. just a question - when would you use /31 and /32 subnets?

[@elstrapo7]

Thank you so much! Our facilitators here in Nigeria tells us that we'd have to suffer like they did to learn networking. 😢 I fell in love with subnetting after watching this 😢 I can explain to my colleagues now 😮

[@divineabazie8918]

Hello. I'm from Nigeria too. My only question is why he multiplied 4 by 4?

[@marshallhyasi6213]

The question basically asks to create 3 subnets and each of these 3 will have it's own 3 subnets ( so the total required is 12 subnets FROM THE MAIN Network ID). So basically in this method (subnetting a subnet), we need to do the following: -Draw the table. -See the prefix of the actual main subnet (in our case /26). -See what number corresponding to the 26 ( which is 3 but we use 4). -We multiply this 4 (from the table) by the REQUESTED 4 (from the question). -We see the answer is 16 (4*4) meaning the new subnets that will be created will have /26 prefix and 16 total subnets. -We create a subnetting table (like the first video). that contains all the info such as network id subnetting number of hosts and broadcast.

[@georgesherpa]

what?

[@yeshua5978]

thanks to clarify I was getting confused with the old video I though it was the same 3 subnets for all departments and basically each deparment needs 3 subnets currect
