@Generated(value="jsii-pacmak/1.89.0 (build 2f74b3e)", date="2023-10-26T00:56:06.979Z") @Stability(Stable) public class CfnVPCCidrBlock extends CfnResource implements IInspectable
Associates a CIDR block with your VPC.

You can only associate a single IPv6 CIDR block with your VPC. The IPv6 CIDR block size is fixed at /56.

For more information about associating CIDR blocks with your VPC and applicable restrictions, see VPC and Subnet Sizing in the Amazon VPC User Guide .

Example: 

 Vpc vpc;
 public void associateSubnetWithV6Cidr(Vpc vpc, Number count, ISubnet subnet) {
     CfnSubnet cfnSubnet = (CfnSubnet)subnet.getNode().getDefaultChild();
     cfnSubnet.getIpv6CidrBlock() = Fn.select(count, Fn.cidr(Fn.select(0, vpc.getVpcIpv6CidrBlocks()), 256, (128 - 64).toString()));
     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_27)
         .vpc(vpc)
         .ipFamily(IpFamily.IP_V6)
         .vpcSubnets(List.of(SubnetSelection.builder().subnets(vpc.getPublicSubnets()).build()))
         .build();
