IPv6 (Internet Protocol version 6) is the recent Internet Protocol (IP) designed to replace IPv4. It provides a vastly larger address space (128-bit addresses vs. 32-bit in IPv4), enhancing scalability and flexibility. IPv6 improves security, simplifies network configuration, and supports modern internet requirements, ensuring long-term growth. IPv6 is essential due to IPv4’s address exhaustion. It offers a larger address space, improved security, and supports the expanding internet-connected devices, ensuring sustainable growth and innovation in networking technologies.
In this Cloud Lab, you’ll learn about IPv6 and why we need IPv6 over IPv4. After that, you’ll create a VPC with an egress-only gateway in the private subnet. You’ll then launch two EC2 instances in the VPC, one in the public subnet and the other in the private subnet. Then, you’ll use EC2 Instance Connect to access the public instance and connect to the instance in the private subnet. Lastly, you’ll verify the functionality of our egress-only gateway by pinging an IPv6 address.
By the end of this Cloud Lab, you’ll have hands-on experience creating a VPC and security group and deploying multiple instances in public and private subnets. You’ll deepen your understanding of IPv6 capabilities and its practical application in securing and managing network traffic within modern infrastructures.
The following is the high-level architecture diagram of the infrastructure you’ll create in this Cloud Lab:
