```
    Indicates whether a network interface created in this subnet (including a network interface created by RunInstances) receives an IPv6 address.
    
    Returns:
    
    Indicates whether a network interface created in this subnet (including a network interface created by RunInstances) receives an IPv6 address.
  - hasIpv6CidrBlockAssociationSet
```
public final boolean hasIpv6CidrBlockAssociationSet()
```
    For responses, this returns true if the service returned a value for the Ipv6CidrBlockAssociationSet property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - ipv6CidrBlockAssociationSet
```
public final List<SubnetIpv6CidrBlockAssociation> ipv6CidrBlockAssociationSet()
```
    Information about the IPv6 CIDR blocks associated with the subnet.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasIpv6CidrBlockAssociationSet() method.
    
    Returns:
    
    Information about the IPv6 CIDR blocks associated with the subnet.
  - hasTags
```
public final boolean hasTags()
```
    For responses, this returns true if the service returned a value for the Tags property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - tags
```
public final List<Tag> tags()
```
    Any tags assigned to the subnet.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTags() method.
    
    Returns:
    
    Any tags assigned to the subnet.
  - subnetArn
```
public final String subnetArn()
```
    The Amazon Resource Name (ARN) of the subnet.
    
    Returns:
    
    The Amazon Resource Name (ARN) of the subnet.

```
    Indicates whether DNS queries made to the Amazon-provided DNS Resolver in this subnet should return synthetic IPv6 addresses for IPv4-only destinations.
    
    Returns:
    
    Indicates whether DNS queries made to the Amazon-provided DNS Resolver in this subnet should return synthetic IPv6 addresses for IPv4-only destinations.
  - ipv6Native
```
public final Boolean ipv6Native()
```
    Indicates whether this is an IPv6 only subnet.
    
    Returns:
    
    Indicates whether this is an IPv6 only subnet.
  - privateDnsNameOptionsOnLaunch
```
public final PrivateDnsNameOptionsOnLaunch privateDnsNameOptionsOnLaunch()
```
    The type of hostnames to assign to instances in the subnet at launch. An instance hostname is based on the IPv4 address or ID of the instance.
    
    Returns:
    
    The type of hostnames to assign to instances in the subnet at launch. An instance hostname is based on the IPv4 address or ID of the instance.
