- This is Video 4 of the Subnetting Mastery video series. In this video there are four more practice problems to provide further demonstrations of the method and cheat sheet. The first two problems are fairly straight forward. The second two demonstrate a couple specific peculiarities you might encounter in the real world.
If you feel comfortable with the content of Video 3, then at least watch the last two problems of this video. They will show you some situations that might cause confusion if you come across them in the future.
What if there were a single video series that could make you a Subnetting Master? What if that video series were available for free, for everyone?
Look no further. This is it. This video series will make you a Subnetting Pro.

I've tried to understand subnetting for at least 12 years and this method is really helping. Thank you!
Great to hear! If you have any questions, feel free to ask =)
All of the HOURS I spent using Messer's "7 second subnetting" and all of the other 'guides' on how to subnet and THIS is exactly what I needed. I feel like a GOD - you are seriously amazing. THANK YOU!!!!!!!!!!!!!
Wohooo! Congrats on attaining Subnetting Mastery! Glad it all makes sense now =) You're very welcome, Priya!
Yeah I feel like messers videos work for info dumping when you need to memorize facts, not so much for stuff like this where you actually have to learn a new function
Dude, I found your video series through the r/CCNA subreddit. This is absolutely amazing and helped to tie together a subject I've been fighting with for a long time. Thank you for this!
Hi Moskeeto! So glad you've enjoyed the series and that its helped you learn subnetting!
Hey good to see you on here from IG.!
It is unbelievable that your videos are still relevant in solving CCNA problems. You are the best Tutor I've ever met, thank you.
Thank you. So glad you're finding this content helpful. If you're interested in more, all my CCNA related content is here: www.practicalnetworking.net/index/ccna/
spent tremendous amount of time and watched quite plenty videos but never explained and elaborated at the same time made easy like you did Sir.
Thank you
Thank you for the kind words =) I'm glad you found these videos helpful!
This simplifies subnetting so much. Oh, Man. Thank you.
You're very welcome. Please don't reck me =)
@@PracticalNetworking what about /24 and lower???????????????
Finally, an explanation that was straight to the point and clear 👍👍
Great video. I finally understand it now. Great examples that make you think. I was ready to throw in the towel on subnetting and take my chances on the exam. You're a lifesaver.
You're video teaching was the breakthrough I needed to wrap my head around and finally understand Subnetting! I am so grateful to you for taking the time to make these video teachings available for free! I don't have much money and I am changing careers into the IT field. This has always been a dream of mine and you are helping me to make it possible! No good deed goes undone! Thank you and God bless you, Sir!!
Hi Tracey. So glad this series helped you! If you liked these, you'll probably also like the rest of my CCNA content: www.practicalnetworking.net/index/ccna/
The best video guide for subnetting by FAR. I struggled to get it on my own when studying for my Network+, but this video pushed me through everything. It all clicked! Thank you a ton!
The lesson and chart are fantastic but the subnetting calculator is the bomb! This helped turn three days of frustration into an ahha moment. You know your stuff. Thank you.
Excellent, Martino! I'm so happy you had your "ahha" moment =).
For the past two weeks, I've been struggling to understand. Through these videos, I finally hit a breakthrough. Thank you for taking the time to prepare and present this video.
Glad to hear it, Richard =). Congrats!
You are a gentleman and a scholar, sir. Thank you so much for making these
good work practice network. this video eliminate any sub netting confusion + reduce the calculation time half than before.
Fantastic. Congratulations!
This is a great video series, I wasn’t able to catch on to this IPv4 subnetting through my CCNA 1 class and I don’t think my instructor has any ideas of how to explain it. Thank God for your videos because I wouldn’t have passed my class without it!
I'm glad you found these videos as well =). Feel free to pass them on to the other students in your class!
I did the practice problems and I was so happy! I'm learning, and I understand why my answers are my answers! Your subject matter goes from broad to specific and is organized in a very practical way! Thank you for helping us!
That's great news! So glad it's all clicking for you. Happy to help!
I have been struggling with this for 2 weeks now and this blew the doors wide open for me. I'll be knocking down these in class tomorrow morning and moving forward! Thank you!! This is Awesome. Everyone has told me to use Prof. Messer, this broke it down Barney style!
Glad this series helped =). Goodluck knocking these down in class tomorrow =). Remember, with great power, comes great responsibility.
Very greatly explained, one-stop solution for all the subnetting calculations
Best guide i've seen on the topic no doubt. Great teacher right here
Spent hours watching people from Udemy/CZcams trying to understand subnetting, just never clicked. I saw about these videos from somebody who posted on reddit. Practical Networking, you deserve a big 👍. This makes it so easy for me now to subnet. Can't believe that is so easy to grip once someone like you has managed to find the simplest explanation. Will recommend your series to anyone who is still struggling to understand subnetting. +1 Sub here
Thanks for your subscription =). Glad you found these videos and can now subnet. THanks for the kind words!
PS: Out of curiosity, where did you see it linked on Reddit =) ?
I can't thank you enough!!!! I feel free because you are explaining every side of the calculation of sunetting. You are greatly appreciated.
You're very welcome. So happy this is all helping with your Subnetting journey =)
so glad i came across your playlist when trying to learn subnetting for the first time. I was able to do all the examples super easily, and based on the other comments, I feel like I saved myself a looot of headaches lmao. You made this super easy for me, thanks a lot!!
Stumbled across your video on a Reddit thread link earlier today.This has helped me speed up my subnetting immensely! This will help me when I take my CCNA later this year. Thank you for this!
Glad it helped! You're welcome =)
I never even knew about this cheat sheet, I feel cheated lol. This saves so much time though and makes me more confident now in my subnetting abilities. Thank you so much! I will recommend this playlist to anyone who asks how to subnet.
Thank you. Glad this gave you more confidence =).
this vid with the practice link at the end made me feel like an expert. Well done
Much respect from Puerto Rico. This video series is simply excellent. Thank you so much.
You're welcome! You might also like this one: czcams.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html
The best one I have come so far. Thank You!
Glad you enjoyed it !
the practice subnetting is priceless. thank you!
Hi again Jonathan, glad you enjoyed them! =)
This concept was so confusing and I spent weeks to get over it on other sources. Found your videos yesterday and I am able to crack all the subnetting problems in < 60s! Thanks bro! Subscribed to your channel !
That's great, so happy to hear that! Thank you for your support!
thank you and everyone that encourages and makes learning possible.
You're welcome, Jon =)
Thank you for this series I am a noob in networking and other videos I came across were confusing, this showed clarity from the onset. Well done!!!
Thank you for the kind words, and you're very welcome =) Glad you enjoyed these !
you are my angel my only angel you make me happy when skies are gray. Im crying of pain reading the Cisco document how to subnet i never had any experience with IT and im emotional that you saved me. Thank you so so so much for these videos i will definitely share to those who suffer :-)
This is the first song someone has sung to me on CZcams. Thank you!
Glad you found these videos helpful. Thank you for your support in sharing the content.
good last two problems!!! Glad you included those.
;) Yup. Those can be tricky, wanted to provide examples before turning students lose to practice on their own.
Thank you for creating this!
This is a God-send.
Thank you
Thank you for your videos. Great work.
You're welcome!
Dude, incredible teaching how you explain so clear and understandable. You really help me a lot. Thanks for this.!!!
Glad it's helped you, Rikardo. =)
Hey bro. Could you help me with some examples of the VLSM with the third and second octects?
Thanks a lot for this video, for the past two to three weeks I had been watching several instructors video but some how was not able to grasp the idea fully and I was doubting my capabilities. Luckily while having coffee the other day I thought give one more try and am so glad I found your video on CZcams. Am so happy finally I cracked this and doing good in the problems generator. :-)
Ajay! That's awesome! I'm so happy it makes sense now! No need to doubt your capabilities anymore =)

i can't thank you enough for this (haven't even finished all vids yet still 4/7) but it's helped me out so much. currently studying for my ccna. I owe you a beer man !
That's awesome. I'm glad it's all beginning to click =).
If you're interested, we're going a step further with Subnetting in a live stream today and Saturday. Details here: www.practicalnetworking.net/announcement/ip-aggregation-and-supernetting-upcoming-live-streams/
this is the most simplest way of explaining this, thank you very much. i just had to subscribe
Thank you for subscribing. Glad you enjoyed it =)
Thank you so much. I've been struggling to find a method to help me and your method is by far the best. It really help me in my study for the exam.
You're very welcome =)
Thank you brudda. You sorted my gray matter right out. Cheers.
Absolute quality. Thanks a bunch!!
You're welcome!
Thank you for providing this easy solution
Easy as ! excellent resource
Heads off to you mate !
Thank you, Tee. Glad you enjoyed the series =)
Do more videos on CCNA please! You are the best instructor hands down!
Thank you for the kind words, Karen. I have more CCNA content posted here: pracnet.net/ccna
This is really great, but going from these examples to a /16 in the generator was mind blowing lol Thanks for making these vids!
Glad you liked them, Robert =). Hopefully Videos 6 and 7 in the series will make /16 (and anything /1 - /24) less mind blowing. =)
WOW, this is SO easy to understand now! I was racking my brain trying to figure out how to do this myself, but as with everything there is always an easier way.
I'm so glad you found these videos =). Glad it makes sense now.
Wow amazing, very detail and also best explanation with more cases. Thank You Sir, God bless you.
Glad you liked it! You're very welcome.
Brother thank you so much. You make things so clear. I’m forever grateful. Keep up the great work. Let us know if there’s anything we can do other than subscribing and liking your videos.
Spreading the word would be the other thing =) There are too many people out there still struggling with Subnetting. I'd love for them all to learn just as you have =). Thanks Jakeem!
Awesome simple and easier than writing out several charts for my upcoming exam!
Glad it was helpful! =)
i wish i found these videos before i sat my Network+. After so many months this is the only method I understand. Alot of people praise professor messer. But he makes me more confuse. Will be watching all your networking videos before i sit the cert again. Already subscribed. You deserved it
Thank you, Printassia. I'm glad you enjoyed this method and these videos. Good luck with your next certification exam! The Networking Fundamentals series will also probably be helpful for you:
www.practicalnetworking.net/index/networking-fundamentals-how-data-moves-through-the-internet/
(although, at this time, the series is about halfway completed at this time).
@@PracticalNetworking 🙂 the networking fundamentals playlist is what Ive been going through since last week, after completing the subnetting mastery playlist. I’m on the switches part 1 video. So we are both thinking the same.
I’ve tried to use your tool for exercises but the first problem was a /20 and I got lost cause didn’t know how to use you CC. Btw you are doing a great job and it’s really easy to understand. Thank you
This is Just Amazing. Please upload video for Network fundamentals like TCP
Spot on. Gold Mine! Thank you Sir. I wasted a lot of time with the other resources. I wish i found this sooner
Your'e welcome! Glad you enjoyed it.
Thank you , i enjoyed watching your videos.
Those are covered in part 6 of the series. =) There are links in the description.
Currently prepping for the ccna ..... your a life saviour 👍👏👏
Glad to help =). Don't forget to check out the rest of my CCNA content: www.practicalnetworking.net/index/ccna/
Bro... HANDS DOWN, best subnetting tut out on the web. Some tutorials are overly complicated methods, some try simplistic approach that I feel doesn't cover all the bases. This cheat sheet has helped me to get a grip on how to answer subnetting questions. My problem is that I'm taking my CompTIA Net+ tomorrow online and not allowed to use scraps of paper.... they want you to use a virtual whiteboard function PearsonVue exam application and is kind wack for writing things down but w.e, first thing Ill do is create my cheat sheet.... thank you so much!
Erick that's awesome! Glad to hear you're getting your head around Subnetting questions. Yes, most certification exams don't allow bringing notes. But they do provide a way for you to quickly jot down notes. That's the benefit of this cheat sheet is how easy it is to quickly jot down the three lines at the beginning of your exam.
Thank you, very clear and helpful.
You are welcome, Gary!
Wow best ever explanation...
Bless u!! 🥰
Cheers!
You are the best..I finally understand this.
In that case, I'm so glad you found these videos =). Don't forget to practice at SubnetIPv4.com !
Thank you sir, this is really helpful
Thanks bro, It was really helpful!
I almost gave up bro!... like for real for real you saved me
Glad you didn't give up =).
Excellent! Thank you so much. I found the cheat sheet very helpful :-)
You're welcome =)
This was really helpful..thank you
Can confirm after several videos, this was the easiest for me to understand.
I' am also currently in a CISCO course and found this video easier to understand than the QA teacher :D
My company is paying for the course but 2.5k is joke when I can get the info in videos lol
I blame myself for not finding this channel sooner!
Glad you found it now =)
I walked out of my networking college class very upset. Even with a very good GPA, subnetting just wasn't clicking for me. I had no idea what each value meant, why we incremented in certain ways, etc. This series is solving all my issues with the topic and I feel so much more ready to perform with each video in the series. My notes are also super organized as the video structure is also organized so well. Thanks so much!!!
thank you thank you!!!! you deserve awards
Thank you for the video
Wow u are really helpful 😊 thanks
I cant believe i could learn this. Thanks a mil
You're welcome, Lydia. I'm happy you've learned to Subnet from these videos =)
amazing content
You're explanation is better than my CISCO teacher in college
Glad you enjoyed it =)
Very awesome and helpful video
Thank you =)
@@PracticalNetworking can you please make a video on STP please!
Thank you so much man😊
That's an amazing content! I watched Professor Messer, Mike Myers, Sunny network academy, some other resources, they were all understandable, but confusing.
Your vuseo is clear and concise, finally helped me to put all bolts and nuts together!
Subscription and Like from me :)
Artur! That's awesome, I'm so glad it finally sunk in.
Thanks for the kind words, and the like/subscribe. I appreciate it!
@@PracticalNetworking LOL! thanks man i also follow above mentioned videos and didn't understood anything thanks to this video series now i have the confidence to subnet
@@lahirupriyankara2183 That's great, Lahiru! I'm so glad you found this set of videos helpful =)
@@PracticalNetworking Can confirm...Currently in training for a job and the school side did explain the concept I somehow could use it in docker but never really solve it that fast.
I solved all 4 problems probably within 5 or 6min. My personal problem was to calculated the subnet of the before and after and the BC-adress.
You just made my evening with these steps
yes this makes it way more simpler compared to everything else ive seen.....even the famous professor messer didnt explain is as good. i was still confused after watching his.
Best explanation!!!!!
Thanks
You're welcome!
Sir, Can you make series on software engineering.......
No good content on CZcams.
It will be very helpful
@@anasmanjothi It's on my list. But my background is Network Engineering. So it will be a while before I can understand Software engineering enough to teach it.
I've started to learn developing though and am enjoying it.
Simple. Elegant.
^_^ Thanks for the kind words!
Such an amazing series! Just loved it! You are a really really cool teacher!
Also, can we also have one video on supernetting, please? :D
Thank you, Paritosh.
I am weighing up making a "VLSM on paper" and "Aggregation / Supernetting" appendix video to add to this series. Do you think those would be useful for students?
@@PracticalNetworking Yes, it will be much helpful for students! Supernetting and subnetting go hand-in-hand in the university curriculum.
WRT VLSM, it is sort of a pre-requisite/assumed knowledge when we study network design, making it really important. Also, isn't VLSM just so interesting? :D
This is gold!
Thank you =)
Finally now I'm an official sub-netter, thank you very much.
Congrats Adam! Happy for you!
Hallo Ed,
You as a teacher have following qualities.
1. you know how to teach (this is quite rare but still one might be lucky to find)
2. you know how to make people learn (almost impossible to find)
3. you know how to make people retain knowledge (this skill not there any more in this world)
Wow, thanks Preetam =) Such kind words! I appreciate you taking the time to comment and am so happy you have gotten a lot out of my content =)
Bro, your teaching is just amazing. Thank you so much. Want to know what and why is /24 and so on. Or do u have other video about this.
YOU ARE AMAZING
I love you for this.
=)
this helped it click for me along with Jason Dion's glove tricks I am just having trouble counting up in 64/32 increments
thank you for ur clear illustration. how do i know when i have to increase the size until i pass the target..
You're welcome.
You will increase the size until you pass the target for every problem.
Bless you!
Cheers!
The best tutorial
Thank you =). Glad you liked it!
Great-Great-Great!!!!
I am attempting to navigate to the subnetting practice page referenced in the video, but I'm receiving a 404 error stating that it isn't there anymore? Please let me know if there is any recourse available. Thank you very much for this whole subnetting series, and I will be viewing your other material as well. Short, to the point, concise, and the concepts are very clearly explained and demonstrated. You earned a sub for this one.
Currently I'm studying for my CCNA. I'm on ICND1 practice, and this subnetting series is great! I especially enjoy your cheat sheet. Very helpful!
Hi there. Glad you enjoy the videos and articles! Thanks for the Subscribe ;)
The practice page is working for me... here is the full link, try that:
www.practicalnetworking.net/subnet.html
Also, if you're interested in a concise list of every article I've written that overlaps with ICND/CCNA curriculum, check out this link -- I just put the list together for Reddit:
www.reddit.com/r/ccna/comments/8zmafo/studying_for_the_ccna_youll_want_to_read_these/
Oh wow, I was only typing www.practicalnetworking.net/subnet.
My apologies, it is working properly! Heads up for anyone doing the same thing I suppose! I appreciate the prompt response. Thanks again!
Ah, yea, that makes sense. The "shortcut" URL is "pracnet.net/subnet", which automatically redirects you to www.practicalnetworking.net/subnet.
Good luck with the studies!
Forever relevant!!!!
Men, you rock!
Best site for parctice thnx
You're very welcome, Darshan =)
Are you going to cover the special case of /31? rfc3021 - Using 31-Bit Prefixes on IPv4 Point-to-Point Links. Also the use of /32 for things like loopback interfaces.
Hi John. I cover /30 and /31 networks for point to point links in the VLSM video here: czcams.com/video/amKyfbg5G2Q/video.html
I don't cover loopback interfaces in this series.
I found this video incredibly useful but I am studying for Comptia Net+ as I assume a lot of others are that come to this video. This solves for /25 CIDR to /32 but how do you handle the CIDR thats lower? Or is that not a concern regarding the exam?
Thank you
You're welcome
