spending whole semester dealing with a fine strategy to solve subnetting questions ,and here we go 9 minutes of explanation and all my doubts solved .that's magic of correct teaching method.
Sir you are truly gifted. I have direct this video to many people and it was like the heavens opened up. I did have to watch a few times to get the rhythm, but it was worth it. I now understand how to do a subnet. Thank you so much.
OMG- After having one of the worst Cisco teachers EVER and struggling with subnetting for over a year. Your 10 minute video cleared all confusion and made it soooo simple. THANK YOU
Failed CCNA exam twice thinking I had it both times. I'm not sure if I want to go for a third. That thing is pure, ego-destroying evil . Feels like I've been assaulted in a dark alley by a gang of 1's and 0's, all of which were of course, wearing /masks. You win Cisco.
excellent teaching. by correcting the IP Address from 192.168.1.47 to 192.168.1.46 shows the teacher is well experienced in Network and Broadcast addresses
Thank you so much !! I watched your other videos. Your way of explaining things are excellent to people like me who are new to this area. Thanks again for your great work !!
Truly speaking ........have you noticed that on the right side the IP Addresses are in 192.1.1.0 network.......and the left side is 192.168.1.0 network..........the concept is fine but I can argue with that because he said it can't be in the same subnet .......
I like your videos a lot! I just want to point something else out: Unless I'm wrong, you should have 3 subnets there because the connection between routers is also a network! It is a little confusing the way it is presented. Having said that, TY for uploading, and I appreciate the hard work you put into these! Matt
Cant thank you enough,, i have seen tons of videos on IP subnetting but nothing helped, This video is awesome,,,you made it so simple and easy for beginners like me!!!!
You probably dont give a shit but does any of you know a tool to get back into an instagram account? I was dumb lost the login password. I would appreciate any assistance you can offer me
Having been a graduate of Cisco Acadamy in 1998, this is a great refresher. I just wish I did not have a unknown sickness from making me study harder and obtain my ccna. My first job would have made me make well over 70,000 the first year. I install routers and switches all day long just that the remote cisco engineer does the software and want to break away from Nationals and have my own customers.
Hernan Hernandez I didn't know ANYTHING about subnetting before I watched this video. And after I did, I practiced on subnetting.net and managed to solve almost all problems. This guy is great!
Good apart from the fact that the right hand network is 192.1 when the left is 192.168. I'm not the best by a long shot, but surely the subnet isn't as important
@relisys001 Yes, if the netmask is 255.255.255.0 then they are both on the same subnet or network, 192.168.1.0 /24. To make to subnets 192.168.1.0 and 192.168.1.128 you would need netmasks of 255.255.255.128
I"ve been looking around and this is one of the most simpliest technic i've seen. thanks: I didn't even notice the IP's I was more concerned ont the break down. thanks:
Duh!! Double-Duh!!! I have always been able to see the powers of the "borrowed" borrowed bits. Ie. 128 & 64 place. Two bits. 2 to the 2nd power = 4. Four subnets. But what really drove it home is when you pointed out the position value of the 2nd borrowed bit, "magic bit", in this case 64!!! Yes! I see the light! I was using up a whole page of notebook paper on each subnetting problem. I can do them in my head now.
yes you could say that. When you subnet a network from say a /24 to a /28 (255.255.255.240) you are breaking the one network into multiple smaller networks
@danscourses hahaha, It was there in front of me, Ive been working so hard to learn this stuff my brain had switched off. Id got the /25 CIDR Notation in my head (because thats what you started with on your white board) and couldnt figure out how they could be not ben on the same subnet, but to get the fact that /24 is 255 (one whole subnet), where as you where doing /25 which is 2 ;-) Thankyou so much
It was not professional Dave, it was done off the cuff in class with no script and no prior preparation, and it is free. I think everyone gets the point of my subnetting techniques even with the minor imperfections. Also, the point you are making is old news, I put an annotation note at the top of the video letting everyone know there is a mistake.
this explanation is indeed right if you consider having 2 networks then the correct answer is /28 but you wrote "all addresses should start with 192.168.1, i wrote 192.1.1 by accident Thanks to mikjet to point out " on the top of the video, then the answer /26 would be correct.
I know it was 5 months since you posted this comments, but I just had to point it out. You said "this explanation is indeed right if you consider having 2 networks then the correct answer is /28 but you wrote "all addresses should start with 192.168.1, i wrote 192.1.1 by accident Thanks to mikjet to point out " on the top of the video, then the answer /26 would be correct.". That is incorrect, because if you have two networks using the same IP addresses there can be problems. Imagine you have PCs with the IP 192.168.1.2 ans 192.168.1.3 on one network. And then you have the same IP addresses on two PCs in the other network. Now, if you were to ping from 192.168.1.2 to 192.168.1.3, you would only be pinging the PC in your own network. You would never get to the thetwork over on the other side, because the router would not know that you wanted to go there.
I was using the term “Least significant Bit” but magic number is way cooler. Totally lost about the 192.168.1 on one network and 192.1.1 on the other. How one network is subnetted has absolutely nothing to do with how another network is subnetted as far as I can tell. Thanks for enlightening us.

Woah! The way you explained this, solved all my questions regarding sub-netting. You made it look so damn easy! Kudos! :)
Your videos completely made me get subnetting. I was struggling with it until i watched your videos!! Thank you so much.
Been a struggle but not anymore after watching this video! You are such a genius in explaining...
Thanks Dan! This really helped! Been struggling for AGES!
Probably the best VIDEO on this I've come across on this subject.Thanking you.
Excellent work on this. Far more understandable than other subneting video/articles I've watched/read.
I have to disagree. Just because he knows his stuff doesn't mean he can teach it very well. This video is a great example of that.
Killed Fromafar I found this easier to learn than other videos I've seen and articles.
Yup, despite the two mistakes, this is very nicely laid out.
Exactly what I was looking for. Going to ace my exam now. I love UA-cam.
I'm still learning the basics of subnetting & don't understand it in totality but this has helped me tremendously. Thank you!
thanks, i've watched many videos on this and each time it gets a bit clearer... your's is nice and simple and to the point, great stuff
Failed CCNA exam twice thinking I had it both times. I'm not sure if I want to go for a third. That thing is pure, ego-destroying evil . Feels like I've been assaulted in a dark alley by a gang of 1's and 0's, all of which were of course, wearing /masks. You win Cisco.
Thank you so much. I missed this class. One class makes such a big difference.
excellent teaching. by correcting the IP Address from 192.168.1.47 to 192.168.1.46 shows the teacher is well experienced in Network and Broadcast addresses
Thank you Dan ... your videos are the best teaching videos I have found on this subject.
Great Job at explaining at an easy to understand level! I've watched several videos on this subject. This easily one of the best!!!
Dude i've been trying for months to understand this!! and just 1 day of watching your video and i passed the test!
Thank you so much for the help!!
Out of curiosity: are you still in networking?
Thank you so much !! I watched your other videos. Your way of explaining things are excellent to people like me who are new to this area. Thanks again for your great work !!
Truly speaking ........have you noticed that on the right side the IP Addresses are in 192.1.1.0 network.......and the left side is 192.168.1.0 network..........the concept is fine but I can argue with that because he said it can't be in the same subnet .......
Correct! This would only work if all of the segments were on the 192.1.1.0 subnet with the corresponding Masks
I like your videos a lot! I just want to point something else out: Unless I'm wrong, you should have 3 subnets there because the connection between routers is also a network! It is a little confusing the way it is presented. Having said that, TY for uploading, and I appreciate the hard work you put into these! Matt
Great Vid Dan. Ive been trying to grasp this concept for a while now, and this is the first time it "clicked" Well done!
Cant thank you enough,, i have seen tons of videos on IP subnetting but nothing helped, This video is awesome,,,you made it so simple and easy for beginners like me!!!!
Thank you dan, im really enjoying these videos its helping me learn a heap for my CCNA. keep posting definitely appreciate it! your a great teacher
I just wanted to say. Thank you SO much for this video! SOOOO MUCH HELP
This definitelity changed the game. He said it's a hard questions. Now it's easy. Thanks +danscoures
That sneeze freaking made me jump.....
Thank you! You made it easy to comprehend subnetting. I have the basics of it down after watching this.
Initially struggled but eventually got it, thanks man !!
You probably dont give a shit but does any of you know a tool to get back into an instagram account?
I was dumb lost the login password. I would appreciate any assistance you can offer me

i'm studying for net+ and man this really helped.. thanks!!
This was eye opening to me. Great help, thank you
You definitely have me as a subscriber now, keep making videos :) your explanations are the easier I've found thus far for anything networking.
I hope I'm not exaggerating, but this honestly taught me everything I needed to know regarding subnetting. Very clear! Thanks!
Hey man, I feel the same way. This video literally blew my mind.
Hernan Hernandez I didn't know ANYTHING about subnetting before I watched this video. And after I did, I practiced on subnetting.net and managed to solve almost all problems. This guy is great!
Yeah Eddie! Absolutely, I've been watching other videos but nothing compares to this one. Keep it up Networking bud
Thanks so much for this.. N+ exam in 2 days and I now know and can explain to others what a subnet is and how to work out magic numbers.
Great explanation. Thank you so much.
Excellent demo.its cleared my concept of subnetting
Good apart from the fact that the right hand network is 192.1 when the left is 192.168. I'm not the best by a long shot, but surely the subnet isn't as important

Even with the 'mistakes' I found this video easy to follow , easier than my text . Thank You.
Wow. And damn it at the same time. My phone got stolen and the person who stole it subscribed to your channel, I watched it and it was amazing!
Wow, thank you. Something finally clicked in my head based on what you said!
Thanx...helps me get a better grasp on how to quickly subnet.
Its nice to see someone put subnetting into context and have a diagram. My teacher only wants to teach the math part.
thanks, your videos have helped me so much. . keep up the great work!
I"ve been looking around and this is one of the most simpliest technic i've seen.

You are right mate, he made it look so damn easy! Really, he just made me a subnetting master now! :)
Thank you for your nice video. That helps a lot of people.
Perfect explanation sir, i really appreciated it..
muchas gracias por la explicacion
thank you very much, well explained
Nice, this is super clear, unlike some french writers >.>
That was an awesome video and a great tip for those taking certs!
Best one ever!!!! Thanks for that and all clear!
Very useful video and very easy to understand. Thank you
@danscourses Thanks, I am getting ready to take my CCNA exam soon and enjoy doing these.
Dude..thanks alot, YOU made it very simple.
yes you could say that. When you subnet a network from say a /24 to a /28 (255.255.255.240) you are breaking the one network into multiple smaller networks
great video..give me perfect explain
that's one hell of a six u created there! thanks man it helped allot
That was so clear and easy, thanks.
Great explanation, thank you!!
Excellent explanation!
Awesome tutorial.
Thanks
Very clear and precise.
despite few slips this vid was excellent! thx man :)
Thank you very much your explanation very good.
@mikjet Yes I think you are right, all addresses should start with "192.168" thanks for pointing out the mistake.
or the 192.1.1.0 /24 address block
my professor you are the best .
Thank you!!! great video very easy to understand~
thank you man.. its was really helpful.. thank you again.
Thanks dude, awesome solution !
@mikjet I posted an annotation to let viewers know. Good job on catching that.
Yes, finally got it! Thank you !
Good explanation. Thanks!
good video well done i found it easy to understand and some funny moments
Hey this is really gr8 , thankuuu so much for this explanation..!
this video helped me understand prefixes so thanks
Thank you so much this video helped out a lot!!!!
awesome refresher!
Awesome videos, thanks.
this is amazing video Ezxprt is also IT professional Academy
Amazing
i have watched Videos on youtube studied books
but this video gave me the understading of subnets
Thanks Dan you are Great !!!
@danscourses hahaha, It was there in front of me, Ive been working so hard
to learn this stuff my brain had switched off.
Id got the /25 CIDR Notation in my head (because thats what you started with on your white board)

Thankyou so much
Well done Sir. Thanks so much
thx sir it was so clear great God bless you
Others video,s show only theory....
you show real world scenarios thx great teacher
Thank you so much.. you made it easy
Nice and easy to understand. Thanx
great vid. Nice work!!
Very helpful to me!
