I've tried to understand subnetting for at least 12 years and this method is really helping. Thank you!

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!!!!!!!!!!!!!

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!

It is unbelievable that your videos are still relevant in solving CCNA problems. You are the best Tutor I've ever met, thank you.

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

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!!

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!

Spent hours watching people from Udemy/KZfaq 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

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!

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 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.

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.

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 :-)

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!!!

I can't thank you enough!!!! I feel free because you are explaining every side of the calculation of sunetting. You are greatly appreciated.

Best guide i've seen on the topic no doubt. Great teacher right here

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)

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.

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!

Finally, an explanation that was straight to the point and clear 👍👍

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!

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

You are a gentleman and a scholar, sir. Thank you so much for making these

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

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 !

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!!!

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!!

Thank you for the clarification on when to increase when you run out of space within ipv4 addresses!!

Much respect from Puerto Rico. This video series is simply excellent. Thank you so much.

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 KZfaq. Am so happy finally I cracked this and doing good in the problems generator. :-)

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.

Do more videos on CCNA please! You are the best instructor hands down!

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 !

good work practice network. this video eliminate any sub netting confusion + reduce the calculation time half than before.

This is really great, but going from these examples to a /16 in the generator was mind blowing lol Thanks for making these vids!

this vid with the practice link at the end made me feel like an expert. Well done

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.

Dude, incredible teaching how you explain so clear and understandable. You really help me a lot. Thanks for this.!!!

This simplifies subnetting so much. Oh, Man. Thank you.

Currently prepping for the ccna ..... your a life saviour 👍👏👏

Awesome simple and easier than writing out several charts for my upcoming exam!

the practice subnetting is priceless. thank you!

Very greatly explained, one-stop solution for all the subnetting calculations

I almost gave up bro!... like for real for real you saved me

this is the most simplest way of explaining this, thank you very much. i just had to subscribe

thank you and everyone that encourages and makes learning possible.

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

Wow amazing, very detail and also best explanation with more cases. Thank You Sir, God bless you.

The best one I have come so far. Thank You!

Awesome, Thank you so much for this video series. That explanation was very clear and perfect. 😍😍🥰🥰

You're explanation is better than my CISCO teacher in college

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.

Good news, everyone! The problem generator is now available at an easier link: SubnetIPv4.com.

good last two problems!!! Glad you included those.

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 :)

Thank you brudda. You sorted my gray matter right out. Cheers.

Finally now I'm an official sub-netter, thank you very much.

I blame myself for not finding this channel sooner!

thank you thank you!!!! you deserve awards

You are the best..I finally understand this.

Spot on. Gold Mine! Thank you Sir. I wasted a lot of time with the other resources. I wish i found this sooner

This is a God-send. Thank you

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.

Easy as ! excellent resource Heads off to you mate !

This is Just Amazing. Please upload video for Network fundamentals like TCP

Wow best ever explanation... Bless u!! 🥰

Absolute quality. Thanks a bunch!!

I cant believe i could learn this. Thanks a mil

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!! 🤣🤣🤣

Thank you for providing this easy solution

Thank you for creating this!

Thank you for your videos. Great work.

Excellent! Thank you so much. I found the cheat sheet very helpful :-)

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.

Thank you , i enjoyed watching your videos.

Thank you, very clear and helpful.

your video is amazing thanks simple explanation

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.

Correct me if I'm wrong because I'm new to subnetting and you have much more experience than me, but I think when it comes to determining the number of subnets and hosts, I think this chart may be flawed. Maybe I'm overthinking it, but here's my thought process: the number of subnets = 2^x, where x = the number of host bits turned on (the number of ones) the number of hosts = 2^x - 2, where x = the number of host bits turned off (the number of zeros) The example at 3:53 is a class A IP Address, which means the first octet is for the network, and the last 3 octets are for the hosts. So the number of host bits in total are 24. Of those 24 host bits, 17 host bits are turned on (they are 1s), so 2^17 = 131,072 subnets. (I'm assuming your "# of IP addresses" is the number of subnets). That means 7 of those host bits are turned off (they are 0s), so 2^7 - 2 = 126 hosts (usable addresses). So I guess the hosts (usable addresses) part is fine, but I'm concerned about the part about the subnets. Don't get me wrong, bless you for making this cheat sheet because it's so simple to understand and I love it, but I don't know if I just confused myself more about how to figure out the subnets. Could you please clear this up for me?

This is gold!

The best tutorial

this helped it click for me along with Jason Dion's glove tricks I am just having trouble counting up in 64/32 increments

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.

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!

Thank you sir, this is really helpful

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

Forever relevant!!!!

New to TECH. I'm taking the try hack me course on subletting and I randomly found your course. YOUR VIDEOS/TRAINING ARE THE BEST. I am working my way up the later, but I do not want fall into a rabbit hole. I am searching for help desk position, end game Security Engineer Professional. Are your videos for Network+ or am in the wrong location??? Please assist....

Best site for parctice thnx

Thanks bro, It was really helpful!

Simple. Elegant.

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!!!

thank you for ur clear illustration. how do i know when i have to increase the size until i pass the target..

It is nice work. You could in advance have included an examble with a prefix 17 to illustrate what then happens. Because it is a different story. Because the last octet will then be 0

Bless you!

Best explanation!!!!! Thanks

Wow u are really helpful 😊 thanks
