It has been 30 years since IPv6 was defined as the L3 protocol for the next generation. Many enterprises, service providers, and telecommunications companies are now actively planning to migrate to IPv6 to support a variety of use cases including NFV, hosting and more. In OpenStack, we have supported it since the Cactus release, and now, in Queens we improved IPv6 support on storage services and we are closer to supporting a cloud fully operating with IPv6. However, the transition of a cloud to IPv6 is not a trivial task, as the network design change comes with its own set of challenges.

In this presentation, we will give an introduction to IPv6, showing what has changed in comparison to IPv4, focusing on its advantages and how it affects OpenStack. We will also show tips and tricks to remember when setting up your IPv6 OpenStack cloud, a basic IPv6 network topology for OpenStack, from controllers to provisioned VMs, and a demo working with storage services, like Cinder and Manila.
