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!!!!!!!!!!!!!
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!
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. 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/
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.
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/
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!
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!
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!
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.
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!
Spent hours watching people from Udemy/RU-vid 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 =) ?
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.
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!!!
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 RU-vid. Thank you! Glad you found these videos helpful. Thank you for your support in sharing the content.
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.
Did you use the problem generator? Did you solve all seven attributes? Reply to this comment with the IP address, Subnet Mask, and seven attributes you resolved.
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
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!
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)
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.
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 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.
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 !
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!!
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 RU-vid. 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 =) Join us for the live stream tomorrow and Saturday, we're going a step further with Subnetting: www.practicalnetworking.net/announcement/ip-aggregation-and-supernetting-upcoming-live-streams/
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/
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
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 :)
@@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
@@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.
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!
I can't lie, I went on ahead and solved the last example and sat there with 256 only for homeboy to tell me we can't have 256! LMAO am dead!! But this really saved me!!! THANKS A LOT!! 🤣🤣🤣
Hi. I feel like you could have precised that so far, we're only able to solve ip subnets from /25 to /32. If I were to go on the website rn for more practice, I wouldn't be able to solve a subnet with /20 for example. That's a little confusing but great job still.
I thought I finally got it by the end of this video. Then I went to the problem generator. I got the first one correct. Oh sweet, I got this. The next one that came up had a CIDR of /21 and I was like oh crap... that's not on my cheat sheet!!!
@@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.
Problem with subnetting is practice. Tedious problems like subnetting ones require thousands of problems done before you actually learn them. They are so quickly forgettable.
@@PracticalNetworking I had so many negative experiences with math and CS that I developed antibodies for it. But ... have to learn it. It took me a year and three months to learn subnetting and I still don't know it. And it is just incredibly annoying. Subnetting, that is. But people gotta do crazy things to survive in capitalism.
Isn't that cheat sheet only for class C networks, though? If the address is 10.2.2.88 /27 , like in the first example, how would we know that only 3 bits are borrowed from the last octet, as opposed to 3 from the last octet and 8 from the previous octet (making a total of 12 bits borrowed, thus many , many more subnets)? thanks!
The cheat sheet can be extended to handle all octets. Videos 6 and 7 will show you how. As for borrowing bits... the problem/question ought to include the starting point, for the very reason you mentioned: /27 could be borrowing 3 bits from a /24, or 11 bits from a /16. If the problem/question doesn't explicitly state a starting point, then typically the problem expects you to infer it from the IP addresses' Class -- Class A / Class B / Class C. The issue is IP Address classes have been legacy for nearly 30 years: www.practicalnetworking.net/stand-alone/classful-cidr-flsm-vlsm/
