To IPv6 - The Dual-stack Adoption Advisory Panel


Authors:   Rags Srinivas, Bridget Kromhout, Lachie Evenson, Tim Hockin, Dinesh Majrekar


The presentation discusses the implementation of IPv6 in Kubernetes and its potential benefits for end-users and developers.
  • Kubernetes can abstract the challenges of IPv6 addressing and make it easier for developers to adopt
  • IPv6 implementation in Kubernetes can make pods addressable and routable on the internet, which can be dangerous without proper education and resources
  • The addition of optional APIs in Kubernetes allows for more control over IPv6 implementation
  • The goal is to have more end-users up on stage discussing their experiences with IPv6 implementation in Kubernetes
The speaker mentions the potential danger of making pods addressable and routable on the internet without proper education and resources. This highlights the need for more resources and education for developers to understand the implications of IPv6 implementation in Kubernetes, such as the need to secure pods from potential cyber attacks.


We all know we’re running out of IPv4 addresses. Kubernetes introduced the current implementation of dual-stack networking (supporting both IPv4 and IPv6 at the same time) in v1.20, and the dual-stack feature graduated to stable in v1.23. While the world has been slow to adopt IPv6, it is happening. It’s time to learn about using dual-stack to start your own move away from IPv4, supported by changes in Kubernetes components such as pods and services. Join for the discussion as SIG Network members and Kubernetes contributors dive into the technical details underlying the move to dual-stack networking, and leave with recommendations to shape your IPv4/IPv6 rollout strategy.Click here to view captioning/translation in the MeetingPlay platform!
