First, thank you SO much for this video series. Before watching, I had used Keith Owens, James Messer, and Jason Dion and all of them have their benefits in terms of detail or practicality. However, your video series absolutely solidified the practical application of subnetting as none of the others had. It just totally nailed it for me. I can do it now. Thanks again! This leads me to a question. Is there a reason you don't list the seven questions in an order that would make the arrangement more sequential? This pattern always leads to a 2/3 sequential relationship. Two IP's in sequence, Three IP's in sequence. Network/ First IP (2), Last IP,/Broadcast/Next Net (3). For example: Target: 10.1.1.37 /29 Network ID: 10.1.1.32 First IP: 10.1.1.33 Last IP: 10.1.1.38 Broadcast IP: 10.1.1.39 Next Network: 10.1.1.40 # Of IP's / Usable: 8/6 CIDR / Subnet: 255.255.255.248
Yea, if I'm honest that is a more sensible way of laying it out. The truth is the 7 attributes were listed that way in my notes when I made the video. I didn't think to optimize the order. Maybe at the time I chose intentionally not to, to further highlight that you can solve for each independent of the others. But yea, if I could tell the me from 3.5 years ago when I made those videos to make the order more sensible, I definitely would have =)
@@PracticalNetworking this tutorial series needs to be preserved in the Library of Congress ....it is a valuable learning resource that must never be forgotten!
To help me remember the seven attributes of subnetting, I reordered them in sequential order (according to what Frank44060 said) and used the following mnemonic: "NFL Broadcast Next In Channel" ....if you list that vertically then it looks like.... N F L Broadcast Next In Channel which translates to Network ID First Host IP Last Host IP Broadcast IP Next Network IP addresses total CIDR/subnet mask Other than that, I just remember that subnet mask, Network ID, and Next Network are the first three things I gotta find then the rest will be easy.
For those who just got here, I assure you that you can learn subnetting with this guy! I've not found any paid or free content such well done and easy to understand, I really appreciate it. Thank you, Ed!
I have had subnetting explained to me a half dozen times and still walked away scratching my head. I felt like such an idiot!! I don't feel like an idiot anymore. Thank you so much for being such an excellent teacher!
Just started my CCNA. Man does it feel scary after my first 10 days. Subnetting in particular. You explained things that I couldn't understand 3 days in a classroom with a guy that is being paid to teach this to us. Thank you!
I've taught many CCNA classes, and I think I found the best way to teach Subnetting. I hope I captured it in this video series. Thank you for the kind words.
You honestly need more view. No bad quality video of a piece of paper, no dude with horrible sounds quality in front of a white board doing horrible drawing, straight to the point, and simple to follow. You managed to teach me something that took my prof 4 weeks to barely scratch the surface. Thank you so much.
Thank you for the generous super thanks =) It's folks like you that support the continued development of free content! I'm thrilled that you enjoyed this series and other content on the channel. Thanks again, Abdul!
This is the best video on Subnetting and Subnet mask. I tried to understand these concepts multiple times from various people and resources but failed consistently to understand these concepts. By going through the series of videos - subnetting mastery, I am able to understand them just like that. Thank you so much and appreciate your efforts in making these concepts simpler.
I can't believe it!!! He is literally explaining and answering every single part of subnetting something that I have been struggling to find and to understand. Thank you very much, coach.
I'm studying for the Google IT Support Professional Certificate and this explanation is far better than the one provided in the course. Thank you! Liked and subscribed!
been studying for my networks final all day and havent felt like i fully understood subnetting. and the examples and visuals you did in the first 2 minutes unlocked my brain. THANK YOU!
Found your videos after 5 weeks of working for Network + Cert. Your videos made more sense than the damned explanation Certmaster has for Subnetting, and the book I got had 3 questions and 1 PBQ regarding subnets on my network + test today and passed. highly doubt I would have passed if I had not found your videos. Thank you!!!!
Why isn’t this the number one result when searching subnetting. So concise. Quality Production. I’ve seen videos with ten times the views with crap quality video and audio, confusing, and scrambled that I leave as confused or more than when I started. I literally send this link to everyone that asks for help with Subnetting. Thank you a thousand times over for this.
If I knew how to market better these videos might get more attention. =) But it seems I am better at teaching than I am at marketing. =/ Thanks for sharing this content, Talan. I appreciate the kind words.
BEST BREAK DOWN OF SUBNETTING ON THE INTERNET!!! I HAVE BEEN SOOOO FRUSTRATED FOR THE LAST 2 WEEKS TRYING TO UNDERSTAND SUBNETTING BUT THIS VIDEO DEFINITELY HELPED PUT 2 AND 2 TOGETHER!! THANK YOU SOOO MUCH :)
I gotta say BEST VIDEO ON SUBNETTING EVER. I've tried to learn it from a lot of UA-cam channels and you are the best. I thought I wasn't smart to ever get subnetting. you made it so easy. please make more courses on IT. THANK YOU SOO MUCH for your help.
This is one of the best video series to understand details about subnetting, Eddie Your mission is to take complex concepts and explain them in a simple.

No doubt blend of passionate teaching along with good presentaion skill , not forgetting the crystal knowledge on networking, makes the master piece. But sadly very less people are exposed to this channel. I recommended friend of mine. He was surprised too. I am truly blessed to encounter this channel. May everyone be blessed too. Thank you so much.
wow all i can say is thank you... ive watched at least a dozen videos on subnetting and this is the best. The diagram on the left really helped out!!! thank you again!!!
Came here from a reddit share and actually understood this first video. Apparently I'm not the only one who lost hours learning from other sources. I'll finish the playlist tomorrow, hopefully the last one on this subject.
@@PracticalNetworking Yeah I finished it, you're the subnetting GOD, everything was clear. The only issue I have is, sometimes a quiz asks to calculate subnet without giving CIDR, only x.x.x.x. I posted this in later videos, not sure how to solve it.
@@am33x Odd, I can see the e-mail from that comment, but not the comment anymore to respond. Strange. In any case... in those situations, you are looking at a legacy / outdated question. It's asking you to infer the Subnet Mask from the Classful address (i.e., the first Octet). This article has more details: www.practicalnetworking.net/stand-alone/classful-cidr-flsm-vlsm/ But again, in the world of Networking after the mid 90's, providing a Network ID w/o a Mask as a starting point is incomplete information.
All your videos I have watched and taken notes on , are excellent. You have a gift for explaining concisely and in an engaging manner, much appreciated.
Moving on to this set after Networking Fundamentals, I'm already in it to win it. Purchased Ed's courses on OpenSSL and OSPF, and will be tearing into them after this playlist. LOVING IT!
you literally saving my student life with these ipv4 subnetting series... I couldn´t understand nothing until i watched the series. Thank you so much for making these videos!

Hey Ed. I just subscribed to your Practical Networking channel. I saw your video on Utube while viewing programming and database videos. I have a systems administration background, but I was not sure what certification to pursue. Also, I passed the CompTIA A+ examination in July, 2013. Your Networking Fundamentals video sparked my interest in Networking. Your style and methods of teaching these concepts through your slides and explanations fit my learning style. I have watched dozens of your videos. You are a terrific teacher. Thank you, Ed. I have been watching your videos - sometimes twice or thrice - and enjoyed and learned a lot. I plan to take the Cisco CCNA certification test soon after thorough Packet Tracer labs.
Hi Rajendra. Thank you for the kind words. I'm so happy you've gotten a lot out of the Networking series =). If you're wiling, the best way to bring attention to this content is via word of mouth. I'm sure you have peers that could also benefit from this content. Sharing would be greatly appreciated =). Cheers Raj! Good luck with the CCNA!
Subnetting is simply taking a list of individual IP addresses and grouping them together. The number of IP addresses never changes, but the number of groups does based on how you subnet/group the IPs.
All the videos in the series are available here: www.practicalnetworking.net/stand-alone/subnetting-mastery/ Want to learn the Fundamentals of Networking? www.practicalnetworking.net/index/networking-fundamentals-how-data-moves-through-the-internet/ Studying for the CCNA? Here are free resources to help you learn: www.practicalnetworking.net/index/ccna/ If you enjoyed this content, don't forget to show your support by liking, subscribing, and sharing this content amongst your peers. That would really help me out. Thank you!
Thank you for the kind words, Pratik. =) Do me a favor... you probably know other people that are trying to learn Subnetting.... Could you share this content with your friends / collogues / classmates ? It would be doing me a great favor.
watching this video during quarantine while lifting weights in my garage, my laptop is on the trash can right now on top of a rag. I'm studying for CCNA 200-301. I didn't quite get the /24 /25 /27 etc.. but I know I will. Next video !
Im studying for it as well...got my exam scheduled in 7 weeks time and still didnt fully understand subnetting but I hope I will with this video...also I should start a workout as I gain 10kg in last 7 weeks :( Keep up with the CCNA and the lifting !
Again i wanted to thank you, i watched so many videos and been in class for this topc but thanks to your video series i fully understand ipv4 subnettig, yesterday we started with ipv6 in class. And again, my prof is more confusing then helpful. Would be nice if you would do a series on ipv6.
Thank you so much for this. I have been trying to find an easy way that helps visually understanding subnetting. Studying for my Network+ exam and hope to be ready for it by end of October or beginning of November. Get this on udemy or LinkedIn learning. I think many will like this.
Now that you know what each of the seven attributes of subnetting are, check out Part 3 to learn how to solve ALL of them in 60s or less! ua-cam.com/video/5-wlfAdcmFQ/v-deo.html
If you do 159-128, you get 31. But that's not the right operation. You have to count all the IP addresses between (and including) 128 - 159. For example: 17-12 = 5. But [12,13,14,15,16,17] has 6 entries. Hope this helps!
I just start watch this video. Thanks for it! I сome up a little poem for remember 7 attributes The seven attributes subnet trust me you need, to be a great! ID subnet, IP broadcast, IP host one, IP host last,, say me how many address, finde next network and you success. I'm sorry i forgot for mask and CIDR for addition task. I'm not a native and hope for this not a big grammar mistakes. Hopefully useful)
I speak to that in this video: ua-cam.com/video/zmxLg4jV0ts/v-deo.html It has to do with Binary. I teach on binary in this video: ua-cam.com/video/RrJXLdv1i74/v-deo.html (although, the binary video doesn't specifically speak to your question)
I really like this methodology for solving the seven attributes of subnetting and have watched the first 7 videos so far. That said, I've come across a real-world type practice problem that confused me (maybe from the way it was worded) because I couldn't use the techniques I learned to solve a subnetting problem like this: You are given a single class C license: 197.40.12.0/24 and need to create three subnets that support at least 10 users. What subnet mask will work? You're given four choices and the choice "255.255.255.192" was the correct answer. I just want to know how I can apply what I've learned so far to answer this kind of subnetting question. Thank you.
First, thank you SO much for this video series. Before watching, I had used Keith Owens, James Messer, and Jason Dion and all of them have their benefits in terms of detail or practicality. However, your video series absolutely solidified the practical application of subnetting as none of the others had. It just totally nailed it for me. I can do it now. Thanks again!
This leads me to a question. Is there a reason you don't list the seven questions in an order that would make the arrangement more sequential?
This pattern always leads to a 2/3 sequential relationship.
Two IP's in sequence, Three IP's in sequence.
Network/ First IP (2), Last IP,/Broadcast/Next Net (3).
For example:
Target: 10.1.1.37 /29
Network ID: 10.1.1.32
First IP: 10.1.1.33
Last IP: 10.1.1.38
Broadcast IP: 10.1.1.39
Next Network: 10.1.1.40
# Of IP's / Usable: 8/6
CIDR / Subnet: 255.255.255.248
Yea, if I'm honest that is a more sensible way of laying it out. The truth is the 7 attributes were listed that way in my notes when I made the video. I didn't think to optimize the order. Maybe at the time I chose intentionally not to, to further highlight that you can solve for each independent of the others.
But yea, if I could tell the me from 3.5 years ago when I made those videos to make the order more sensible, I definitely would have =)
@@PracticalNetworking Your humble reply is so refreshing. But yeah, it totally works either way! I can't thank you enough for this series.

@@PracticalNetworking this tutorial series needs to be preserved in the Library of Congress ....it is a valuable learning resource that must never be forgotten!

I have watched dozens of your videos. You are a terrific teacher. Thank you, Ed. I have been watching your videos - sometimes twice or thrice - and enjoyed and learned a lot. I plan to take the Cisco CCNA certification test soon after thorough Packet Tracer labs.
Hi Rajendra. Thank you for the kind words. I'm so happy you've gotten a lot out of the Networking series =).
If you're wiling, the best way to bring attention to this content is via word of mouth. I'm sure you have peers that could also benefit from this content. Sharing would be greatly appreciated =).
Cheers Raj! Good luck with the CCNA!
OMG this is so easy, this is one of the best videos in the internet.
Glad you liked it! Thanks for the kind words =)
Enjoying and finding that there is such simplicity and thoroughness in explaining subnetting. 😮Thank you for your fantastic videos! 😊
Great video compilation. Learned more in this 8 1/2 minutes than I did for 2 years at a local tech school! Thanks and keep up the good work.
Thanks for the kind words =) So glad you enjoyed the video!
Amazing explanation.
i recommend to every one that watch this video twice or three time even you think you have understand in on fell swoop.
Thank you, Maqsoom!
Welcome
Finally an explanation I understood! Great visualization!
Very nice video. I feel very confident on subnetting after watching this.
Excellent! I'm glad these videos helped =)
you guys should be paid for this. thank you for the awesome work!
Thanks for the kind words =) Glad you enjoyed the videos!
thank you so much Ed for these lessons they make subnetting very easy.
You're very welcome!
Subnetting is simply taking a list of individual IP addresses and grouping them together. The number of IP addresses never changes, but the number of groups does based on how you subnet/group the IPs.
Yes thanks for these video's, been trying it the Professor Messor way and I just don't understand it. These videos have simplified it for me so much!

Absolutely brilliant walkthrough! Thank you!
U r the best teacher of my life❤️
Thank you for the kind words, Pratik. =)
Do me a favor... you probably know other people that are trying to learn Subnetting.... Could you share this content with your friends / collogues / classmates ? It would be doing me a great favor.
It’s like the seven wonders of the world … invaluable knowledge
watching this video during quarantine while lifting weights in my garage, my laptop is on the trash can right now on top of a rag.
I'm studying for CCNA 200-301. I didn't quite get the /24 /25 /27 etc.. but I know I will.
Next video !
Ha, love it =) Keep up the good work! With the quarantine, the lifting, and the studying!
Im studying for it as well...got my exam scheduled in 7 weeks time and still didnt fully understand subnetting but I hope I will with this video...also I should start a workout as I gain 10kg in last 7 weeks :( Keep up with the CCNA and the lifting !
I really learned a lot watching your videos. Thanks
Again i wanted to thank you, i watched so many videos and been in class for this topc but thanks to your video series i fully understand ipv4 subnettig, yesterday we started with ipv6 in class. And again, my prof is more confusing then helpful. Would be nice if you would do a series on ipv6.
FANTASTIC, love this one. seen so many others videos that i didn't get, this one, I did.. awesome!
Glad it helped! =)
Well done. The timestamps are appreciated!
Thank you so much for this. I have been trying to find an easy way that helps visually understanding subnetting. Studying for my Network+ exam and hope to be ready for it by end of October or beginning of November. Get this on udemy or LinkedIn learning. I think many will like this.
Hi Jonathan, I'm so glad you enjoyed the content =) Thanks for the tip about Udemy and LI Learning!
@@PracticalNetworking not a problem. the visuals right away help. maybe be worth to share the graph.
Now that you know what each of the seven attributes of subnetting are, check out Part 3 to learn how to solve ALL of them in 60s or less!

Thanks for uploading this video. Your help is greatly appreciated 😊
Glad you enjoyed this =)
Best explanations, thank you very much
along with the exapmle questions this is invaluable
Glad you liked them =)

Im confused.. at 4:43 when you show that .128 to .159 is 32 ips .. im only counting 31.. what am i missing?
If you do 159-128, you get 31. But that's not the right operation. You have to count all the IP addresses between (and including) 128 - 159.
For example: 17-12 = 5. But [12,13,14,15,16,17] has 6 entries.
Hope this helps!
@@PracticalNetworking yes that helps! Thank you. I am a subnetting god now! Been practicing and slaying all of them. Just getting my timing down.
That's what it's all about! Cheers, glad Subnetting is easy for you.
Thank you 😭
Jeremys IT Lab subnetting videos were just not cutting it like these did
Thank you. Once again much appreciated 🤠👍🏾!
Thanks Harold!
Watch practical networking for all your networking knowledge. These videos are great and very easy to follow.
Thanks Pete, glad you enjoy them.
this has always scared me. But here we go!
Great video. Simply the best !
Thank you, Elf =). Let us know what you think of the rest of the series =)
Thank you so much, wonderful explanation straight to the point. Good job! :)
Superb sirc,thankyou.
Steve from the uk
Hi again Steve. You're welcome!
Best subnetting videos!!
Thank you, Freddie =)
I just start watch this video. Thanks for it!
I сome up a little poem for remember 7 attributes
The seven attributes subnet
trust me you need, to be a great!
ID subnet, IP broadcast,
IP host one, IP host last,,
say me how many address,
finde next network and you success.
I'm sorry i forgot for mask
and CIDR for addition task.
I'm not a native and hope for this not a big grammar mistakes. Hopefully useful)
Ha, brilliant. Love the effort =)
still coming back for review! Thanks Prac Net.
Gotta love Apple Cider notation :)
0:39 Why is it called a /24 network in particular? That's where I get confused when working with different CIDR values.
I speak to that in this video: ua-cam.com/video/zmxLg4jV0ts/v-deo.html
It has to do with Binary. I teach on binary in this video: ua-cam.com/video/RrJXLdv1i74/v-deo.html
(although, the binary video doesn't specifically speak to your question)
I really like this methodology for solving the seven attributes of subnetting and have watched the first 7 videos so far. That said, I've come across a real-world type practice problem that confused me (maybe from the way it was worded) because I couldn't use the techniques I learned to solve a subnetting problem like this:
You are given a single class C license: 197.40.12.0/24 and need to create three subnets that support at least 10 users. What subnet mask will work?
You're given four choices and the choice "255.255.255.192" was the correct answer. I just want to know how I can apply what I've learned so far to answer this kind of subnetting question. Thank you.
Great video as all of your vids… well done !
Thank you kindly =).
