Amazon VPC CNI now supports IPv6 Egress for Pods in IPv4 enabled Kubernetes Clusters

Starting with Amazon VPC CNI version 1.13, Amazon Elastic Kubernetes Service (EKS) allows clusters in IPv4 address space to connect with end points in IPv6 address space. This enables customers to operate services in mixed IPv4 and IPv6 environments while migrating to IPv6 only address space-based services. The native support in Amazon VPC CNI reduces the overhead of managing dual-stack cluster configurations and alleviates operational challenges in maintaining application compatibility with dual-stack networking.
