Chapter 4. Networking on AWS

In this chapter, we will explain how to define the IP address block for your virtual private cloud, also known as a VPC. We will start by explaining the Classless Inter-Domain Routing (CIDR) notation, which IP addresses are available for you to use for your VPC, and then the three types of IP address on AWS: public, private, and elastic. Next, we will discuss dividing your VPC into one or more subnets, and finally defining routes for your network traffic in route tables.

The main topics that we will cover are as follows:

  • CIDR notation
  • Private, public, and Elastic IP addresses
  • Subnets
  • Route tables

Now, let's move on to the first section in this chapter, CIDR .
