#### [ CLI ]

**AWS CLI**  
**To modify the enableDnsSupport attribute**  
This example modifies the `enableDnsSupport` attribute. This attribute indicates whether DNS resolution is enabled for the VPC. If this attribute is `true`, the Amazon DNS server resolves DNS hostnames for your instances to their corresponding IP addresses; otherwise, it does not. If the command succeeds, no output is returned.  
Command:  

```
aws ec2 modify-vpc-attribute --vpc-id vpc-a01106c2 --enable-dns-support "{\"Value\":false}"
```
**To modify the enableDnsHostnames attribute**  
This example modifies the `enableDnsHostnames` attribute. This attribute indicates whether instances launched in the VPC get DNS hostnames. If this attribute is `true`, instances in the VPC get DNS hostnames; otherwise, they do not. If the command succeeds, no output is returned.  
Command:  

```
aws ec2 modify-vpc-attribute --vpc-id vpc-a01106c2 --enable-dns-hostnames "{\"Value\":false}"
```
