Associates a CIDR block with your subnet.

You can associate a single IPv6 CIDR block with your subnet.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.ec2.*;
 CfnSubnetCidrBlock cfnSubnetCidrBlock = CfnSubnetCidrBlock.Builder.create(this, "MyCfnSubnetCidrBlock")
         .subnetId("subnetId")
         // the properties below are optional
         .ipv6CidrBlock("ipv6CidrBlock")
         .ipv6IpamPoolId("ipv6IpamPoolId")
         .ipv6NetmaskLength(123)
         .build();
