Brief history of the IPv4 exhaustion problem as well as explaining how CIDR blocks are calculated and used on AWS when creating a virtual private cloud subnet

This is seriously, such a good video. AWS is actually the reason I was curious about the topic in the first place, so your example VPC was 100% relevant to me. You're a stud.

CIDR part starts at 12:25. You're welcome.

THIS IS BEST EXPLANATION I HAVE EVER COME ACCROSS AS FAR AS EXPLAINING HOW THE IP INTERACTS WITH THE INTERNET.THANK SO MUCH RYAN, YOU ARE THE BEST!

[snvpper]

Many thanks for this. As a self-taught developer, trying to define the IP ranges for my VPC subnets was really confusing me. This video explained it perfectly!

Dude, you are a heaven send. I've been sitting here for the last few days trying to understand this stuff and you just helped me get to 90% understanding. A lot better than the 30% I was at 23 minutes ago..

Ryan Schachte, This is a great presentation. thoughtful, specific, and with the right modulation.

One other feature that probably many of us don't know. Which is people with low vision, like, people with Macular degeneration eye problems who see better with black text over white background. So these graphics help to pay attention a lot easier for many people with eye problems. especially older.

halfway later it got in opposite directions. white text on black background. which makes it equally harder. Please have it in your mind for further design improvement.

In the IT industry, most would say "fake it till you make it". With that approach, you may never get the opportunity to grasp basic concepts. This lesson has tied up a lot of loose ends on the fundamentals of IPv4. Thank you!

THANK YOU SO MUCH this was an amazing video, my professor kept explaining CIDR blocks in class but i never got it so i was freaking out about an asignment he gave us but this video made it so simple for me to understand!!

[Rorypandanda]

Wow, watched countless videos and this one is the only video where I feel the concept finally sticks to my head.

[aloutsis]

Don't mean to sound like a fanboy but that was an awesome video to say the least. Step by step, incremental knowledge and real life application and examples. Great

[HelgiFelixson]

I'm studying for the AWS Solution Architect Associate certificate and needed by VPC knowledge beefed up. This video really helps!

[TheVidoefan]

Finally, an actual video about CIDR that makes sense. Thank you so much!

[tulsirai]

This is the best content and presentation available out there to understand CIDR block i.e. choosing IPv4 addresses for AWS VPC and Subnets! It reasons why a certain IPv4 or CIDR block is chosen. Great Job explaining in a way a Novice like me can clearly understand!

[Smaels]

I've read/watched several tutorials on CIDR but now I FINALLY GET IT!! Thank you! Subscribed.

[vammy]

The best explanation indeed.I was hitting my head for few days searching all over the internet to understand CIDR but to no avail.You made it look so simple.Thank you very much.

[gsgunturu]

You nailed it bro. Even a KG student can understand the networking basics form this video. Kudos

[cutemilli]

This is a very helpful video specially for people having absolutely no idea about networking. Thanks a ton.

[ofabinho]

Oh my, your english is very clear. I am from Brazil and it's very peaceful to listen to you haha

[hammadahmed]

Without a doubt the best video available to learn about IPs, subnets and VPCs!

[Piraetsu]

Finally i can understand CIDR completely, thank you very much
