How IP Addressing Works in AWS | Public, Private, Elastic, CIDR Notation | AWS for Beginners

But what’s with all those different IP addresses (Private, Public, Elastic), and how does CIDR notation work? In this video, I’ll explain in simple terms how it all works. We’ll see the differences between the types of IP addresses, and then get into details of CIDR notation (subnet masks and RFC 1918 ranges) and how that all works. 🌟🌟If you’re interested in getting AWS certifications, check out these full courses.
