The process of dividing a large network into multiple small networks called subnetting.
What is CIDR?
CIDR stands for Classless Inter-Domain Network. It is the total number of network bits.

Thanks
Yes my answer is correct
Thanks
Thank you very much. You are awesome. My answer i correct.
Subnet Mask = 2^7 + 2^6 + 2^5 + 2^4 = 240
The total number of networks that can be created= 2^4 =16
Total number of IP addresses on each network= 2^4 =16
Total number of hosts on each network = (2^4)-2=14
I am agree with your answer
good good good good

Subnet Mask: 255.255.255.240 (CIDR /28 = 11110000 in 4th octet OR 128+64+32+16 = 240)
(First 3 octets in are default 11111111.11111111.11111111 OR 255.255.2555 which uses only 24 bits. In order to get to the 28 bits (from the /28 CIDR) we need to turn on 4 bits in the last octet OR 11110000 which equals 240)
Number of Networks = 16
(Borrowed bits in 4th octet squared OR 4 borrowed bits multiplied by 4 = 16)
IP Addresses in each Network: 16
(Value of the last "ON" bit OR last bit set to "1" (4th octet 11110000) last ON bit in 16's placeholder).
Host (assignable) IP's in each network: 14
(IP addresses in each network - 2. One is saved for Network ID and one is saved for Broadcast ID).
Ex: Net 8 in this example (Assuming Nets 1-16):
Net 8 Network ID: 192.168.10.112
Net 8 Broadcast: 192.168.10.127
Net 8 IP Host Range: 192.168.10.113-126
PS: Excellent video!! Thanks for explaining Classes and using exponents and formulas. After watching other videos where the 128 62 32 16 8 4 2 1 were written out over and over your simple exponents cut the time I took to complete a subletting exercise by over half.

You’ve been a great help in explaining in an easy way about this topic, thank you
This is by far to me the best explanation to understand the very basic concept of subnetting. I had been watching, reading a lot of resources with regards to subnetting including from top of the notch instructor on the web like Messer, Dion, Udemy, RUclips, Cisco etc. All of them leads me into confusion, but this instructor is very straight forward. I Understand all of it. I highly recommend his video tutorials to those who are just starting up to the very basics. If only I have five thumbs to give you sir. LOL. But, I have only two. So, two thumbs up for you #Sensei.

Very useful for my pentesting training. Shema, ninga madurai ah ?
Hi Friend,
Very Good and Detailed explanation. Thanks for that.
I have few clarifications.
1. What is the significance of subnetting ?
I understand that it divides a larger network into multiple smaller logical groups. However I am unable to understand where it really helps in practical scenario. Could you please explain that ?
My understanding is that:
Two networks are created based on this "Class C" IP example 192.168.10.0/25
Network 1 IP address starts from 192.168.10.1 to 192.168.10.126
(these IP ranges can be assigned to the directly host)
Network 2 IP address starts from 192.168.10.129 to 192.168.10.254 (these IP ranges can be assigned to the directly host)
How does it helps or make a difference for someone who simply pings any IP ranges within these 2 networks or without having the subnetting ?
For example without subnetting it the Class C IP is: 192.168.10.0/24.
The Network IP address starts from 192.168.10.1 to 192.168.10.254 in one large network and this could be assigned directly to the host too.
Could you please make me clear where the subnetting in practial scenario helps ?
Is it something for the Router efficiency ? Thanks for your further explanation here.
Thanks a lot once again.

subnet mask will be 255.255.255.240
ip address 16
host address 14
but is it right that to find out number of network we should consider all the network bit 24 already and 4 borrowed that is =
2^28 no of network can created
Absolutely correct. Good
Number of networks that can be created = 2 ^ (No. of bits borrowed from host) = 2 ^ 4 = 16.

Excellent break down of concepts related to subnetting!!! Hats off to a tutorial well done!!!!!
Excellent one.Really I have had never ever gone through the video on subnetting ,IP addressing.Well explained.
No words to describe the wonderful explanation, which has finally made this topic clear to me.
This is the best video on subnetting in all of YT.
I have spent hours and days on RUclips and the internet in general, trying to find a tutorial that would explain this entire networking concept to my full understanding and failed to find a single one. If the entire tutorial wasn't poor in explaining the concept, a large chunk of it was and that ultimately left me still struggling to fully grasp the subject. What an utter waste of time all those hours have been for me, because in just 20 minutes you have enabled me to fully grasp this mystifying topic completely. I'm just speechless!!!
You are a GENIUS my friend and I just can't figure out how and why others lack your excellent delivery style in explaining this concept. My ultimate compliment to you is that I'll now be deleting every single one of those bookmarks I created for the previous tutorials and websites because they're all truly and utterly useless to me now.
From this day on, THIS VIDEO WILL BE MY BIBLE for everything on this subject matter. Thank you, thank you, thank you. 👏👏👍👍
