Calico provides the networking layer for Kubernetes clusters, and its Windows implementation covers IPv4 alone. This fork runs Windows nodes on dual-stack and IPv6 clusters: it bootstraps Windows networking, masquerades IPv6 service traffic that falls through, rebuilds the network bridge after a reboot drops it, reconciles routing against Windows’s own routing service, and publishes the resulting images from continuous integration.
