Don’t usually comment but have to show my gratitude. So many tutorials have their own method but this way really helps me solve so many different scenarios consistently without getting stuck. Thanks again.
Dude i've been trying this shit for about 5 hours today and it never clicked, your method of teaching is dope just wanted to express my gratitude. Keep doing whatever you do because you're obviously doing something right in life. Thanks again.
Now that I actually understand !!! I have watched so many vids on subnetting and it feels like rocket science but you have explained it far more clearly, thank you!!
I love you. After 4 and half hours of searching, you solved my problem. My contribution was to make the connection between your 'subnet number' and 'Cascaded Network Address' (which my router software was asking for). Thank you, Thank you, Thank you!
true, that is default but in this case it was subneted, with aditional 8 bit on the third octet. the default is /16 but in this case was subneted to a /24
Oh my gosh!! Thank you so much!! I was thinking it would be so hard to solve, as my book made it complicated to figure it out but this video help out so much! You're a lifesaver!
As a class b net ID it would default to 255.255.0.0 but if you don't need 65,534 IP address then the net admin is able to shorten the scope by setting a smaller subnet mask. But again if youre using a class b subnet you probably need 65,534 ip addresses.
What about this IP?? I have a e-commerce website and have SPAMMERS clicking my ads using this IP range. I CANNOT block these types of IPS. How do I find the original IP?2600:1702:2f30:97b0:e838:1f6f:8bbd:db46
Thank you, what an easy way , very good explained , but what with a pubic IP address you never get to know the subnet mask.or the class from the ISP , you probably do not need it as a home user, but i'm currious.
what will happen if the one octate in ip is 16 and corespoding subnet is 192 then 256-192 =64 but ip is already 16 then what write .. ithink 0 is the answer...
What if the 4rth octect of ip address is less then from the minus value comes out... Like after _ you got 16 and the 4rth octect of ip address contain 14 then what to do how to sum up? 16 we cannot exceed you told... Please tell
In the beginning AND operation where it says "no subnetting," what is happening here if this isn't subnetting? Is that just a conversion of an IP into a subnet number?
@@VLearnIT so if the IP has a 0 and the subnet mask has anything other than a 0 or 255 you just minus by 256 and that is your answer? (in this case 16)
@@rickyray2794 Yes that is correct! You can make a chart as well to make the conversations even quicker if you're taking exams, if not you can do it in your head like you just suggested and that works perfectly fine.
VLearn I.T. I have to take my A+ core 2 (I’ve been putting it off, nervous about studying. I passed my core 1 a few months ago). But after that yeah I’ll be taking my net + so I would definitely prefer being able to do most of it in my head. I’ll be working a bit with it this semester for my sys admin class as well.
In an octet the max value is 255 if every bit is a 1. However, that is not the max number of combinations. It is actually 256 if you include the value of 0... or eight zero bits in the octet.
Dont know what to say, using an IP calculator for the 3rd example with the IP: 192.168.20.73, is getting the result 192.168.20.0/24 or just 192.168.20.0 . I tried with two different IP calculators, same results. However it is an interesting way to calculate.
that network number is 192.168.0.0 but you have a /25 that’s means that your networks goes 192.168.0.0 to 192.168.0.128 so the fit network broadcast is 192.168.0.127

I never feel so comfortable with this explanation; you're rock Thanks
You are my hero!!!!!! Thank you for making this so easy to follow! Love, a formerly frustrated 🥴 IT student
one of the best understandable videos out there.. i am literally watching this during my final semester exams and it totally helped me!!!!!!!!!
I just wanted to leave a comment because I’ve watched lots of videos and this by far explained subnetting better than anything I’ve seen. Thank you
On another example of clear vision, logical reasoning and a great way to explain subneting. Like and subscribe.
10 minutes and now im so much more confident thanks
in the second example 172 is a class b address, so subnet will be 255.255.0.0
true, that is default but in this case it was subneted, with aditional 8 bit on the third octet. the default is /16 but in this case was subneted to a /24
Simple, straightforward. Makes a lot of sense, thank you!
wow every teacher should be like this!
just made my day with that formula. Thank you so much
Thank you very much, this has truly helped me with my exams!

Awesome explanation! Thanx, you make this so easy for me know.
Brilliant teacher
These subnet videos are gold. Can you make an updated version for subnetting?
Superb sir.thankyou.steve from the uk
whats exactlysubnet number ? i have tried to googling and couldnt find any answer.
Hi. I just wanted to know where 256 comes from?
If I may ask, where does the 256 to subtract from comes from. I mean why do you use 256 to subtract and not any number above it, thank you sir
Very nicely explained
In the 3rd example if my ip address is 193.168.20.10, then what could be subnet number?
excellent explanation thank you
How can be the class be subnet mask 255.255.255.0 and it is actually 255.255.0.0 in second question
Yes same confused me too
wa

255.255.0.0 is the default mask but if you subnet it given a different CIDR notation it might be different.
why is it 256?
I love the you teaching ❤
I’m glad I came across this tutorial now.. thank you but why do we have to use the number 256 ?
Saved my life. Thank you
you are a legend fyi , thanks for the series
OMG ..so good explanation
What about this IP?? I have a e-commerce website and have SPAMMERS clicking my ads using this IP range. I CANNOT block these types of IPS. How do I find the original IP?2600:1702:2f30:97b0:e838:1f6f:8bbd:db46
Thank you, what an easy way , very good explained , but what with a pubic IP address you never get to know the subnet mask.or the class from the ISP , you probably do not need it as a home user, but i'm currious.
So does "Classless" practically mean we are reducing the number of hosts because we dont need all of the availability?
kiss on your hands thank you thank you thank you thank you thank you thank you thank you thank you thank you
Do you still use formula for number if value is 254?
Whats the difference between with subnetting and without subnetting?
very well explained thanks
Can I calculate the subnet mask without the cidr notation, only the ip address?
Nicely explained! Cheers mate!
You made it easy.Thank you Sir.
Where did you get the 256 from?
what will happen if the one octate in ip is 16 and corespoding subnet is 192 then 256-192 =64 but ip is already 16 then what write .. ithink 0 is the answer...
Is it? Because I was wondering about the same thing when the octet Is a 2.. u get 64 , but do I put 64 or 0?????
Wait so if I have 3 digits for the first 3 for the second adn the last 2 spaces are also 2 digits then do I use the same subnet mask?
Sir I could kiss you right now. Your methodology is incredible.
Very good tutorial... my only question: Where does the number 256 when you subtract from it with the last octet in a subnet mask come from??
256 is the highest number you can get in a bit (0-255)
Thanx, explained very easy
What if the 4rth octect of ip address is less then from the minus value comes out... Like after _ you got 16 and the 4rth octect of ip address contain 14 then what to do how to sum up? 16 we cannot exceed you told... Please tell
In the beginning AND operation where it says "no subnetting," what is happening here if this isn't subnetting? Is that just a conversion of an IP into a subnet number?
What is the subnet number for 10.0.0.0, 255.255.240.0. When there's an interesting number in between
The answer is 10.0.16.0

?
what would I have to do now?
for class B- default subnet mask will be- 255.255.0.0
how are you able to imediately know what class a IP is?
Why 256 tho ?
THANK YOU! Very easy to understand :))
very incredible but the problem is that they never gave you the subnet mask, so you end up using the end operation.
Is subnet number the same with network address?
Thankz a lot this video jus saved me....🤟
Is the subnet mask correct here at 2:57 ?
Simply if we do bitwise and with each octet we will get the subnet number
is this subnet number same as network id
how would you find the broadcast easily in a subnet like /18 where you have so many available host..?
The first one is network & the last is broadcast.
Where did u pull the number 256 from in the 3rd example??
In the CCNA study guide book by wendel odom called the number "the magic number"
This is fantastic job!!!
so thankful for you ❤❤
Ok, this is life saving!
Never ever take this video down
Now it,s 2021 so came back to TH-cam please
Currently doing the Google cert about this and the way they explain it makes no sense. Thanks for this
How did u get 256?
such a good video, thank you so much youre aweseme!!!!
may i ask on your 3rd example? where did you get that 256 that u subtracted to 240?
In an octet the max value is 255 if every bit is a 1. However, that is not the max number of combinations. It is actually 256 if you include the value of 0... or eight zero bits in the octet.
okay, so he performed '&' (and ) operation between IP address and subnet mask.

Catalin Coconeanu wouldn’t the third example be /28 not /24 cause it’s 255.255.255.240?
Also, is subnet number network number?
why 256?
Where to find the octet number
Take a bow sir...
What happen when we have,
Class c network
Of 192.168.0.0 /25
How to solve this ?
Yeah i am wondering this myself.
that network number is 192.168.0.0 but you have a /25 that’s means that your networks goes 192.168.0.0 to 192.168.0.128 so the fit network broadcast is 192.168.0.127

I'm confused where the 240 came from
Jack, 240 was an arbitrary number chosen for an example.
Vishwanath Biswal
قبل 8 أشهر
Default subnet mask for class B is 255.255.0.0 not the 255.255.255.0 .
So 2nd number example's solution is wrong .
He states for example 2 that he is using a subnetted address and says that it is NOT the default subnet mask for Class B.
You are fool
THANK YOU!!!!
Thank you so much ...
For third example 193.168.20.73 how u have taken the last subnet mask number as 240 can u explain
/28 network but he is using this to just teach the math of finding the subnet address so he way not have said that.
3:08. That subnet mask is incorrect. That is a class c subnet mask
Thank you 🙏
