Finally somebody who claims to make it easy and actually DOES MAKE IT EASY.

After about 20 videos and countless hours, I found this...and it makes sense. This is by far the best/easiest example I've found! Thank you!

2.5 years working in IT and couple of Microsoft exams but this is the best way to subnet ever, no cheat sheets no nothing just pure logic, thank you!!!

9 years later I’m here being so thankful to this video ❤️❤️ I’ve watched like 30 videos explaining this topic but you’ve done it so well and so easily. Thank you so much I need this for my exam 💪💪✨

I'm in CompTIA Network+ class right now, and we just learned to do subnetting last night, and I can tell you that it took MUCH longer for the instructor to go over it than you just did, and it was MUCH more difficult, not to mention confusing. Thank you for sharing this extremely simple method!

Carl, I've been trying to figure out subnetting for longer than I'd like to admit. Your video finally made it click for me. I'm so glad you never relied on borrowing bits, just plainly laying out what the binary is telling us. THANK YOU SO MUCH.

5 years later and this is still the best explanation I could find about this. Thank you so much!

Unbelievable how simple you made subnetting. Like so many others have said, countless videos, hours, textbooks, methods, charts and nothing was a clear and concise as this. THANK YOU!! Terrific video.

"Easy Subnetting": 30+ minutes of theory and confusing analogies. Thank you so much for making this video, I finally understand it after weeks of struggling.

Carl, in all my years of working with technology, this is by far the most straight forward explanation of subnetting / netmasking that I have ever seen. Excellent work! Thank you,.

Carl, Your tutorial is THE ABSOLUTE BEST in this subject--confusing as it is. I'm studying for my CompTIA A+ and subnetting was the only thing keeping me from feeling confident I could pass the exam, let alone finish it! And you put this all together in just 5:40. Thank you so much, Carl! I especially loved the way you did the tutorial using a simple piece of paper and a pencil. It simulated what will actually be the case during an exam.

got a mid-term on wednesday and was just looking for some clear information. fantastic (praise the University of UKposts!! :D)

This is bar far the best subnetting video in my option. I’ve been using this video for the past year. Whenever I get a bit flustered and forget what I know I come here for a quick 2 minutes and everything comes back. Great work!

Ten years later and still Amazing video, I really appreciate it. You already have a new subscriber from Chile

I've seen videos over 30 minutes long trying to explain this and I didn't understand any of them, however, ive learned more from your 5-minute video than I did from any other source, Thanks a bunch :)

13 years after completing my graduation have I understood this clearly here.

ive struggled all semester when it comes to questions about subnetting due to getting overwhelmed. Your clear and calm explanation helped in my breakthrough!

I've seen a lot of "How To" videos concerning sub-netting, and how to make it easy, but this is the greatest of them all by far. Thanks man!

Finally, an explination that delivers what the title says it will deliver.

After watching several "subnet masking made easily" videos, I finally found this video: the first video that makes subnet masking easy! Thank you.

watched this video on my college years. watching it again for my interview assessment. God bless you

This was made 5 years ago and it is the best video I've seen concerning sub-netting.

After 2 hours of rewatching the lecture and reading notes i came across this video and now everything makes sense

Best explanation by far on UKposts and I'm not even a native English speaker ;)

This is worth its weight in GOLD!!!! GOOOOLLLLLLDDDDDD!

I don't usually comment frequently, but I just HAVE TO! I have been searching for videos, reading notes mine and others, watching 3 different Doctors + 3 different TA's as I take it in 3 different subjects, AND YOU JUST made it as simple and easy as that, after HATING subnetting for the past 6 months, I'm actually starting to LIKE it and if possible close to LOVING it. For real, god bless you and your heart, and may your world be as easy as how you made subnetting for me and thousand of others just like me. I thank you for the deep deep of my heart.♥️♥️♥️♥️♥️!!!

I've been struggling with this all day, and this is the first video to actually help me figure this out. Thank you so much!

Carl, you absolute legend!! I have been searching the net for a decade for a simpler explanation of subnetting. Thank God I found this. Thank you🙏👍.

6 months of level 1 Cisco Networking Academy and I just now get subnetting thanks to your video. And my final on subnetting is tomorrow lol. Fuckin' THANK YOU!!!

thank you sweet jesus, saved my ass for an upcoming exam :D

You get the Network address, and you get the Broadcast address, and then everything else in between are the Hosts... wow, you made it super easy to figure this out. Thank you!

I can't even begin to explain how helpful this was. Thank you so much!

Im taking a network technician course and CCNA is part of it. I have not been able to grasp this AT ALL until I saw this video. Now it at least makes sense (i suck at math so binary conversions are already difficult for me). Ive been getting 90's on my exams and am currently on chapt 7 lol. Thank you for this. Its the only video/demonstration that made sense and many people have tried to tutor me IRL and on youtube LOL

Finally! I've watched many subnetting videos and yours is the first one I actually understand lol. Thanks! I take my net+ in July.

This is the simplest explanation of subnetting. Thank you for making this video. Like other commentors, I've gone round the subnetting video circuit, head spinning from various explanations. This video is brief, to the point. Doesn't take lots of time. Subnetting makes sense now.

Thank you so much mate! It's so much better when it doesn't take 30 minutes to explain it like other videos.

I watched so many videos and I have to say that your teaching method is short, sweet, simple and straight to the point.

I wasn't feeling very well this couple of days recently and I missed the lecture. I have a test coming next week and you've just royally saved my ass! Thank you, sir!

Just one minute into your video and it's already making sense! Thank you!

After 10 years, still very helpful! Bless you Carl!

Best explanation, particularly with the part explaining the purpose of every bit to the left of the line vs to the right of the line.

Whole semester confused finally got it. I wish there were more videos. Thank you.

Never heard anyone explain it so simply before! Thank you

I have seen countless of these videos now. This is the best one

You are an excellent teacher! Best and clearest explanation I have ever seen. Einstein said " if you can't explain it simply, you don't understand it well enough."

Bro, after many videos, your 9year old video is the one that still shined.

Thank you dude! You thaught me in like 5 minutes what my teacher at school failed to teach me in about half a year!

10 whole years later, somehow this is the best explanation I've found. Thank you

I have been banging on this door for ages and you have kindly opened it a bit for me!! Thanks!

It's wonderful demonstration. I just got the idea of subneting wit this precise and clear lecture. Thank you!

Thank you so much; a concept that I didn't understand for six months you taught in less than six minutes. I can finally take the Net+ exam.

This is one of the best videos for showing an easy way to do subnetting by hand. Love the method.

I won't say you went in depth but wow, with this video I can go back to my lecture and actually piece together everything, your video was the catalyst I needed.

This is a great video! Simple in its execution and very easy to learn. It has helped me tremendously today as I practice. Thanks Carl!

You're a genius!! Thanks. All the others take a whole freaking hour to show this and put you to sleep.

this is the best way of explaining subnetting that i have seen, that made me snap it instantly all the hours of videos i watched before didn't help me at all. thank God i found this

You took something inconceivable and turned it into something I could understand. You are my new hero!!

You're amazing! After spending more than 1 hour on YT and weeks at school... I finally understood it in about 5 minutes.

This explained subnetting in 5 minutes for what an hour long Coursera course made seem so confusing and complex....thank you.

Thank you so much for this, I tried to wrap my head around this for so long but you made this so easy.

Firstly i did not understand what you were doing, after doing the same thing on paper with a different subnet i found out how it works, i'm very happy with the knowledge it works on all subnet classes , thank you

how tf is this the best explanation I've seen?? This makes it look so simple. Just seeing the correlation between the binary values in subnet and IP made it click for me!

I am here after 10 years you made this video and finally, I have found something easy to learn. Still being helpful even for me and my Englis as my second language, challenging! thanks a lot.

Quiz about this in an hour. You are a god-sent.

The best clarification of subnetting I have ever seen thanks bro

10 years later and still extremely helpful

most helpful video I've seen on the subject. Thank you for keeping it straightforward and simple.

so many years later and you still saving people my bruh

This is probably the best video which explains subnetting very clearly

I have my midterm tomorrow. This helps a lot.

i watched 3 videos of +35 min of what you explained to me in 5 min!thanks

About time a perfect subnetting video.

Thank you for your video! This is the first time I truly understand subnetting!

THANK YOU for posting this I cant believe it took this long to find this, awesome vid and great explanation

Finally, I found this. You don't know how happy I am right now.

Saw a lot of videos with shortcuts, but what I really needed was the "HOW".. and this video explained it.

Wow, this is the best explanation. I was able to get it without replaying the video for a second time. Thanks a lot

Thank you. I've searched for a video like this for days! Subscribed :D

The best and easier way I have seen to subnet. Thanks you Carl Oliver.

So many vids show at least two charts to memorize! You did it with no chart! 🙌🏽👏🏽👏🏽💪🏽

After 2 months I finally found the perfect video that explains this !! Nice one 👍🏻 ❤

Holy crap I had always struggled with subnetting, this video literally made it seem so easy. Thank you so much man

Best explanation. Not even a trained cisco certifier can explain this so easily. God bless!

Watched a few other videos, this one by far made the most sense, Thanks!

Thanks for this video. I have been trying to understand subnetting and watching countless videos/courses but this video gave me the Ah-Ha moment I needed to feel like I have a grasp on the idea of subnetting.

Years ago when I was trying to learn about subnetting I watched countless videos. Then I came across this and all the bullshit everyone else couldnt explain finally made sense. This is the most elegant way to explain subnetting.

Awesome video. I have struggled understanding this for so long, not anymore! This was kinda the last piece of the puzzle. Thank you!

This is by far the best/easiest example I've found! Thank you!

Short & sweet. THANK YOU CARL!

After many struggles this is by far the simplest and most sensible explanation i've found. you're a god man thank you so so much

Working on my Networking+ and was struggling with subnetting. The simple way you explain it cleared the subject right-up for me! Something about the way others try to teach is convoluted and use methods that now seem overly complicated. My future career and I thank you.

Dude this has got to be the best explanation I have found thank you

This was incredibly helpful. Short and concise!

One of the best videos about sub netting.

Wow 5:40mins of precious time and teaching.. It was really helpful and tricky rather than watching 20mins video nith hell confusions.. Thank you so much sir.. 2013-2020 ..

Thanks dude, I was stuck in subnetting from past 3 days. Thanks a lot, now it is all clear :)

Thank you for this video. I watched many other but I still couldn't grasp how to complete the problems correctly. After going through this video step by step, I completely understand and feel confident in taking my exam.

Thank you friend, I just hated this topic whenever taught in the class but you made it simpler and easy.

Finally!! This video is so good and short, I didnt understood it at all and this almost 6 minute video just opened my eyes, and I understand it now! Good job, thank you so much!

Please give the award to this guy. After wasting my 60 mins, I found this. I don't know why you got dislikes.
