Today's Question's Answer:
Subnet Mask 255.255.255.240
Networks = 16
IP Address = 16
Host IP =14

What is Subnetting?
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.

In this video, I have explained to you about:
How to do subnetting.
How to find Subnet Mask.
How to find the number of Networks from CIDR Value.
How to find the number Host of IP Address.

*Answer of the Surprise Test*
The number of IP Address on each network: 2^4 = 16
The number of Host Address on each network: 2^4 - 2 = 14
The total number of the network is: 2^4 = 16
Subnet Mask: 255.255.255.240

[MaharajaTandon]

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 never understood this part in college lectures you actually made it so easy.... Hats Off to the best tutorial for NETWORKING....

[Feathla]

Dude, you are the first person to help me understand this and explain exactly what I needed explaining. Everyone else online I've looked at and the books I've read haven't explained it the way I needed. Thank you so much for making this video. I really appreciate it.

[footfiles]

Hands down the BEST explanation and instructional "illustrations" that I have watched on learning how to subnet. I can't thank you enough for making such a confusing concept digestible!!

[lukejohn]

Wonderful explanation. I think everyone gets confused about sub-netting because its usually not well explained. This video should be mandatory to anyone trying to learn networking :)

[adamcone]

Thank you for actually going through each layer and explaining the network id, host address ranges, and broadcast id. You have helped me so much in preparing for my Network+ certification exam in a week from now!

[arjunreddyaj]

this is the most refined way to explain a topic with clear depiction keep up the great work !

[naveen_satyarthi]

Subnet mask :- 255:255:255:240
Total number of network :- 16
Ip address on each network :- 16
Total no. Of host :- 16-2 = 14

I have spent hours and days on YouTube 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. 👏👏👍👍

[samanthathompson]

This is the best I have ever watched you be made me understand this whole thing more than ever before

[Dariusrae]

Bro knows psychology about how to make beginners understand concepts! This is the Top Quality of an Efficient Teacher!!

[alvacardona]

Thank you so much for explaining it this way! I'm a visual learner, and I need to visualize numerical data in order to understand it.

Subnet Mask: 255.255.255.240 (CIDR /28 = 11110000 in 4th octet OR 128+64+32+16 = 240)

(First 3 octets in are default 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.

The only tutorial on subnets which makes sense. Keep up the good work

[jasonp]

Brilliant sir! This is my favorite video on subnetting. Thank you!!!

[VanMastr]

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, Youtube, 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.

[mnesotaq]

This is the best and most clear subnetting video. Thank you for doing this. I've been watching lots of subnetting videos and they're so bad that I got all confused until I saw this video. Thank you!!!!

[zafar]

Best explaination i hv ever seen on YouTube keep doing the same best of luck

[mpdabs]

I cannot thank you enough, this particular topic was a mystery but you explained this supposedly difficult topic in such an easy manner. Thank you.
