The best explanation i've ever seen. Some lectures just beat around the bush without a concrete resolution. Thank you Sir for this perfect explanation.!!!!
OF all the thousands subnetting tutorials here on youtube, i can pretty say that you are maybe the only few guys, that can explain it clearly ,brilliantly, wthout giving me any confusion, you are simply the best..! it has been 10 years since you uploaded this, but, sir, Thank you for all the effort. stay safe,god bless you
Dude. I swear nobody can explain this where it makes sense.... and then I see this. Thank you! So much easier than I thought. Smh. I’m taking my N+ now lol.
Very well presented and easy to understand. We all have a lot to learn from you! Thank you. :) I've seen this video in the past already, but forgot about the problem and solution to it. Now, after having studied for the CCNA, I came back to check if I could solve it (without remembering your solution from when I first saw your video), and I can proudly say I've managed to solve it very quickly. This feels good, thank you for that as well, Dan! All the best to you! :) Regards, Attila
To be Honest, I'm Moroccan and My English is too basic and this is one of the best sub-netting videos hat i have even seen. Thank you soo much and I created this account just to say thank you for the explanation
Solved it pretty quickly. My gut instinct told me it was the IP addresses. After looking at the CIDR & Mask, had the network id's solved in about 10 seconds in my head. Hopefully this is good enough for the test tomorrow!
Thank you so much for your tutorials about subnetting. Love the simple way you teach! I wish you were my teacher. I like your website too. So informative.
Wow, this was a really good explanation. especially finding out the /27 from binary "count the ones" omg Idk why I never thought of that, I was counting backwards LOL!
In the beginning, everything in IPv4 was designed around classes which was a bad idea because it was not an efficient use of the IPv4 addresses which were running out. So CIDR basically enabled the use of whatever subnet mask you needed regardless of the number. So 174.22.x.x would have been classfully a slash 16 subnet mask but now it really didnt matter because the routing protocol would include the subnet mask in the header and recognize whatever subnet mask you needed like slash 24.
Dan I like your clear and concise video. I really like the fact that their's no BullSh!t computer effects or annoying fancy diagrams that is very distracting. Just the simple white board, arm, and ink!
Does it matter what IP address you assign to your router/gateway? Would you assign the network address to your gateway or would you assign the first useable IP address to the gateway? Does the gateway just have to fall within the subnet range?
my friend took the exam - and he said all he did was gave the router a BGP with neighbor IP with (remote-as) and the network worked and he passed the exam with it. so now im confused. because what if the exam wants you to keep the everything the same but still make the 2 networks talk to each other.?
Does the cidr determine the classification of the subnet mask or does it depend on the question being asked? I thought 173 in the IP address determines the subnet class. Please help thank you
Wow, amazing explaination... you should be teaching at or something like that because I am not good at this and I understood everything. Thank you sooo much!!!!!!!!
so it's better to change the ip address instead of changing the subnet mask to /25 so you don't have to reconfigure the entire network? or both options would be correct?
@vszabad In IPv4 routing's early formation people were limited to "classful routing." Today with classless inter domain routing (CIDR) you are not limited to the classful schemes.
Also I modified books way of subnetting I.Pv6. They did mask say /64 divided by 4 to get number of characters. I just did mask /60 60/16 this then gives result like 3.75. Because each group is 4 characters this would mean that in this address the network is 239A:FCDA:16D::. The result is in 3rd group 3/4 of way in or 3rd of the 4 digits. 239A:FCDA:16DE:5693:ABCD:DCBA:FEA1:CAFE I think this way is a bit quicker, simpler to remember than book. I even verified this on book problems all correct.
On most network, as long as the DHCP server is configured to hand out the gateway IP address and DNS server addresses also... then it should be no problem for a host to get to the internet.
This is the subnet video that made it all clear to me. This video is my epiphany moment for subnetting. Thank you
Explains everything so clear and easy. Amazed.

The first explanation of Subnetting that actually made sense. Thank you!
The best explanation ever.
Good job Dan. You're the best.
You're awesome this is from 2023 an you explained this to me like no other person thank you so much professor
The Best video I have seen after many confusing videos. Thank you, Dan. There is nothing worst than being confused.
Simple, concise and easy to understand. Thank you for posting this tutorial.

Mate, Thank you for taking the time to do these videos i am doing my CCNA at the moment and this has helped a great deal. Really appreciate it.
To be Honest, I'm Moroccan and My English is too basic and this is one of the best sub-netting videos hat i have even seen. Thank you soo much and I created this account just to say thank you for the explanation
like me I am from Jordan and I really love the way of explaination
me too , am from Yemen
Mashallah brother
Dan's videos are downright underrated.
Solved it pretty quickly. My gut instinct told me it was the IP addresses. After looking at the CIDR & Mask, had the network id's solved in about 10 seconds in my head. Hopefully this is good enough for the test tomorrow!
I feel this is the only video actually helpful to me, thanks!
Thank you so much for your tutorials about subnetting. Love the simple way you teach! I wish you were my teacher. I like your website too. So informative.
this dude is the best at teaching, making this easy as pie my guy.
Easy to follow! Well explained! I see your vids being my night before the exam cram! Cheers!
THANK YOU SO MUCH, such an easy explanation to follow is what every student needs
you made it so easy. thanks man. Im downloading all your videos on my phone now
Brilliant explanation dan..it cleared my doubts on subnetting. Thank you
Thank you Dan! Taking my Network + exam tomorrow, my Security + exam in April and on to my CCNA.
Thanks, this is much better information on how to do subnetting and solving those test problems. Awesome!
Awesome ! Iam understanding subnetting for the first time. Thx alot
Dude. You're killin' it! I'm stoked!
Lol. Those were the days. I am updateing my subnetting videos this year. Hopefully the production quality will go up some too!
Amazed, that was an amazing explanation!
Excellent work Dan. I love your videos. Keep up the great work.
Thank you Dan, very easy to understand now compare to all these books that make it so complicated. thanks again.
@SyncPK Cheers. Good for you, the Network+ is tough because it is such a broad range of subjects.
Reminds me of N+ class, except this time around I understand almost everything. 2010, but still just as good. Thanks for the vid!
I love it..All videos that I watched this one make me clear.. Thank you
Very detailed. Thank you very much, wow I learned a lot from a single video than a loong assed lecture. Thank you
Excellent presentation. Thank you good sir.
Sir,you make subnetting easy...! thank you.
Great work Dan.. Very easy to follow.
Your videos are amazing, thanks a ton!
Awesome. Clean presentation. Thanks!
Awesome video sir, waiting for some more videos on problem solving techniques
Very Nice! Im in cisco networking class. Thats help me alot. Thanks
Best video for subnetting.
Excellent work Dan
Thanks mate!! U made it easy to understand
Amazingly Illustrated..! Thanks a lot!!
Really thanks man !! managed to simplify all the process LOL...looks like my school teacher complicates life -.- ...thanks again ey really good job :)
that was so easy and clear. thank you very much
Thanks a lot dans. I bought labs from shopnewused site, they are very very useful after learning from this guy.
Wow, this was a really good explanation. especially finding out the /27 from binary "count the ones" omg Idk why I never thought of that, I was counting backwards LOL!
THANK YOU SO SO MUCH! I FINALLY GET IT :)
This is Magic channel .. and dan you are magician

YOU'RE A GENIUS!!!! THANK YOU!!!!
Thank you so much these videos are very helpful!!!
Wow. This helped me so much.
Very very googd explanation. Thanks for all your videos!!!
Thanks youre a life saver
I needed that!
love the videos dan
Dan I like your clear and concise video. I really like the fact that their's no BullSh!t computer effects or annoying fancy diagrams that is very distracting. Just the simple white board, arm, and ink!
just made my life a lot easier
yes. its a nice tutorial. tnks sir dans
Dan you are a G!
Dan your a badman gangster.
Love from Pakistan and england
finally i found the ultimate subnetting video
now this is concise instruction! Yeah mon!
Great job explaining
yes that clears stuff up for me thanks!
I love the background noise of the running servers :D
I was just thinking that. Lol
nice explanation... i understood very well now..
magic number ,that's lovely!
Very Good Illustration!!
Does it matter what IP address you assign to your router/gateway? Would you assign the network address to your gateway or would you assign the first useable IP address to the gateway? Does the gateway just have to fall within the subnet range?
Brilliant!
my friend took the exam - and he said all he did was gave the router a BGP with neighbor IP with (remote-as) and the network worked and he passed the exam with it.
so now im confused. because what if the exam wants you to keep the everything the same but still make the 2 networks talk to each other.?
DAN IS THE MAN!
nice, this lesson make me clear.. thanks !!!
Thank you for the tutorial.
Does the cidr determine the classification of the subnet mask or does it depend on the question being asked? I thought 173 in the IP address determines the subnet class. Please help thank you
Tnx Dan!
That was good. One thing: I would explain to people unfamiliar with it, what the "magic number" means, -that it's block size.
@danscourses is it safe to say, network+ and A+ certifications were nice to have in the 90's, but now a days....... better to just go for ccna
well that was helpful, subscribed!
Sir, do we need to configure a different router for each network?
Thanks in advance.
Wow, amazing explaination... you should be teaching at or something like that because I am not good at this and I understood everything.
Thank you sooo much!!!!!!!!
Thanks for your videos :)
Outstanding!
Fantastic!!!
knew the problem 30 seconds in, stayed to see the explanation and make sure I was correct. The gateway is in subnet 2, pc's ip is in subnet 3.
so it's better to change the ip address instead of changing the subnet mask to /25 so you don't have to reconfigure the entire network?
or both options would be correct?
Yes
It depends on the situation where you are.
is this method going to work with subnet mask
@vszabad In IPv4 routing's early formation people were limited to "classful routing." Today with classless inter domain routing (CIDR) you are not limited to the classful schemes.
network IP number is the same of gateway ip number?
So the only way to get this PC onto the internet without changing the IP addresses is to use a SM of 255.255.255.128(/25)?
Also I modified books way of subnetting I.Pv6. They did mask say /64 divided by 4 to get number of characters. I just did mask /60 60/16 this then gives result like 3.75. Because each group is 4 characters this would mean that in this address the network is 239A:FCDA:16D::. The result is in 3rd group 3/4 of way in or 3rd of the 4 digits.
239A:FCDA:16DE:5693:ABCD:DCBA:FEA1:CAFE
I think this way is a bit quicker, simpler to remember than book. I even verified this on book problems all correct.
On most network, as long as the DHCP server is configured to hand out the gateway IP address and DNS server addresses also... then it should be no problem for a host to get to the internet.
love you maan
It was useful.Thanks
Prasanna S Thiagarajan hey...any one frm AP
Hello Dan. Wouldn't it be easier to change the subnet mask of the computer since both the router and computer are already on the same network?
I literally had just asked the same question.
appreciated!!!!!one question in the pocket =)
thank you!
thank you so much this has help me and i will go on to your next video LOL
