The primary use case for setting this field is for a StatefulSet's Headless Service to propagate SRV DNS records for its Pods for the purpose of peer discovery. The Kubernetes controllers that generate Endpoints and EndpointSlice resources for Services interpret this to mean that all endpoints are considered \"ready\" even if the Pods themselves are not.

"ipFamilies": "IPFamilies is a list of IP families (e.g. IPv4, IPv6) assigned to this service, and is gated by the \"IPv6DualStack\" feature gate. This field is usually assigned automatically based on cluster configuration and the ipFamilyPolicy field. If this field is specified manually, the requested family is available in the cluster, and ipFamilyPolicy allows it, it will be used; otherwise creation of the service will fail. This field is conditionally mutable: it allows for adding or removing a secondary IP family, but it does not allow changing the primary IP family of the Service. Valid values are \"IPv4\" and \"IPv6\". This field only applies to Services of types ClusterIP, NodePort, and LoadBalancer, and does apply to \"headless\" services. This field will be wiped when updating a Service to type ExternalName.\n\nThis field may hold a maximum of two entries (dual-stack families, in either order). These families must correspond to the values of the clusterIPs field, if specified. Both clusterIPs and ipFamilies are governed by the ipFamilyPolicy field.",
