Properties for defining a CfnVPCCidrBlock.

Example: 

 import software.amazon.awscdk.cdk.lambdalayer.kubectl.v34.KubectlV34Layer;
 Vpc vpc;
 public void associateSubnetWithV6Cidr(Vpc vpc, Number count, ISubnet subnet) {
     CfnSubnet cfnSubnet = (CfnSubnet)subnet.getNode().getDefaultChild();

     cfnSubnet.getAssignIpv6AddressOnCreation() = true;
 }
 // make an ipv6 cidr
 CfnVPCCidrBlock ipv6cidr = CfnVPCCidrBlock.Builder.create(this, "CIDR6")
         .vpcId(vpc.getVpcId())
         .amazonProvidedIpv6CidrBlock(true)
         .build();
 // connect the ipv6 cidr to all vpc subnets
 Number subnetcount = 0;
 ISubnet[] subnets = vpc.publicSubnets.concat(vpc.getPrivateSubnets());
 for (Object subnet : subnets) {
     // Wait for the ipv6 cidr to complete
     subnet.node.addDependency(ipv6cidr);
     associateSubnetWithV6Cidr(vpc, subnetcount, subnet);
     subnetcount = subnetcount + 1;
 }
 Cluster cluster = Cluster.Builder.create(this, "hello-eks")
         .version(KubernetesVersion.V1_34)
         .vpc(vpc)
         .ipFamily(IpFamily.IP_V6)
         .vpcSubnets(List.of(SubnetSelection.builder().subnets(vpc.getPublicSubnets()).build()))
         .kubectlLayer(new KubectlV34Layer(this, "kubectl"))
         .build();
