Tricks to five classes of IPv4

Every networking professionals need to know IPv4 five classes, their first octet, the IP range, their default subnet mask, and the number of hosts per network for each class, Today my topic is how to remember five classes of IP version 4 without memorizing it.
In this 10-minute tutorial, I will break apart five classes piece by piece. By the end of the video, I hope you could be able to remember the table or at least understand how these numbers come from.

Many thanks for your time. Please leave your comments and questions, and do not forget to subscribe my channel. More videos are coming soon.

Many thanks.

This makes so much more sense than my cybersecurity courses! It's hard to memorize these charts when there's no explanation for why these specific numbers are being used. You made it so simple and easy to understand. Thank you!

I'm prepping for a networking job interview tomorrow and wanted to brush up on my networking / subnetting skills (its been 25 years since I took network admin course so I'm a bit rusty. These videos brought back all of the memories and I feel much more confident going into the interview. Thanks!

genius!!! No one ever teaches this topic in such a simple way. This topic can take a whole chapter in my textbook, and no one including my professor is really understanding this subnetting thing. I couldn't believe it is so ridiculous simple. I believe everyone here agrees with me. I was tortured by subnetting for so long. now it is over!
