What is CIDR Block in AWS VPC | AWS VPC CIDR DEMO | Calculate CIDR
Are you new to AWS VPC and looking to understand how to manage IP addresses for your virtual network? If so, you'll want to learn about CIDR notation and how it can simplify the process of IP address allocation. In this video, we'll introduce CIDR and explain how it differs from traditional IP address classes. We'll also walk through an example of CIDR notation in action, showing how to configure IP address ranges for an AWS VPC using CIDR blocks. Whether you're a developer or sysadmin, this video will give you the foundational knowledge you need to get started with CIDR in AWS VPC.
If you're new to AWS VPC, one of the first networking concepts you'll need to understand is CIDR notation. CIDR, short for Classless Interdomain Routing, is a method of defining IP address ranges that simplifies IP address allocation and management. Unlike traditional IP address classes, which are fixed and can be inefficient in terms of address space usage, CIDR allows for flexible allocation of IP addresses to subnets within a VPC.

In this video, we'll dive deep into CIDR notation and show you how to use it in AWS VPC. We'll start by explaining the basics of CIDR, including how to interpret CIDR notation and how it differs from traditional IP address classes. From there, we'll walk through an example of how to configure IP address ranges for an AWS VPC using CIDR blocks.
For example, let's say you have a VPC with a CIDR block of 10.0.0.0/16, which provides 65,536 IP addresses. If you need to create three subnets within the VPC, each with a maximum of 256 IP addresses, you could define three CIDR blocks as follows:
10.0.0.0/24 (256 IP addresses)
10.0.1.0/24 (256 IP addresses)
10.0.2.0/24 (256 IP addresses)
By using CIDR notation to define the IP address ranges for these subnets, you can efficiently allocate and manage IP addresses within your VPC.
Along the way, we'll cover important keywords and concepts related to CIDR and AWS VPC networking, including subnets, routing tables, and network ACLs. We'll also discuss best practices for designing and managing IP address ranges in AWS VPC.
Whether you're a developer, system administrator, or IT professional, understanding CIDR notation is a critical part of mastering AWS VPC networking. By the end of this video, you'll have the foundational knowledge you need to confidently manage IP addresses within your VPC using CIDR notation.
