	// Specify which IP family is used to assign Kubernetes pod and service IP addresses.
	//
	// If you don't specify a value, `ipv4` is used by default. You can only specify an IP family when you create a cluster and can't change this value once the cluster is created. If you specify `ipv6` , the VPC and subnets that you specify for cluster creation must have both `IPv4` and `IPv6` CIDR blocks assigned to them. You can't specify `ipv6` for clusters in China Regions.
	//
	// You can only specify `ipv6` for `1.21` and later clusters that use version `1.10.1` or later of the Amazon VPC CNI add-on. If you specify `ipv6` , then ensure that your VPC meets the requirements listed in the considerations listed in [Assigning IPv6 addresses to pods and services](https://docs.aws.amazon.com/eks/latest/userguide/cni-ipv6.html) in the Amazon EKS User Guide. Kubernetes assigns services `IPv6` addresses from the unique local address range `(fc00::/7)` . You can't specify a custom `IPv6` CIDR block. Pod addresses are assigned from the subnet's `IPv6` CIDR.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-eks-cluster-kubernetesnetworkconfig.html#cfn-eks-cluster-kubernetesnetworkconfig-ipfamily

	IpFamily *string `field:"optional" json:"ipFamily" yaml:"ipFamily"`
	// Don't specify a value if you select `ipv6` for *ipFamily* .
	//
	// The CIDR block to assign Kubernetes service IP addresses from. If you don't specify a block, Kubernetes assigns addresses from either the `10.100.0.0/16` or `172.20.0.0/16` CIDR blocks. We recommend that you specify a block that does not overlap with resources in other networks that are peered or connected to your VPC. The block must meet the following requirements:
	//
	// - Within one of the following private IP address blocks: `10.0.0.0/8` , `172.16.0.0/12` , or `192.168.0.0/16` .
	// - Doesn't overlap with any CIDR block assigned to the VPC that you selected for VPC.
	// - Between /24 and /12.
	//
	// > You can only specify a custom CIDR block when you create a cluster and can't change this value once the cluster is created.
	// See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-eks-cluster-kubernetesnetworkconfig.html#cfn-eks-cluster-kubernetesnetworkconfig-serviceipv4cidr
	//
	ServiceIpv4Cidr *string `field:"optional" json:"serviceIpv4Cidr" yaml:"serviceIpv4Cidr"`
	// The CIDR block that Kubernetes pod and service IP addresses are assigned from if you created a 1.21 or later cluster with version 1.10.1 or later of the Amazon VPC CNI add-on and specified `ipv6` for *ipFamily* when you created the cluster. Kubernetes assigns service addresses from the unique local address range ( `fc00::/7` ) because you can't specify a custom IPv6 CIDR block when you create the cluster.
