**To describe the enableDnsSupport attribute**

This example describes 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.

Command::

  aws ec2 describe-vpc-attribute --vpc-id vpc-a01106c2 --attribute enableDnsSupport

Output::

  {
      "VpcId": "vpc-a01106c2",
      "EnableDnsSupport": {
          "Value": true
      }
  }
  
**To describe the enableDnsHostnames attribute**

This example describes the ``enableDnsHostnames`` attribute. This attribute indicates whether the instances launched in the VPC get DNS hostnames. If this attribute is ``true``, instances in the VPC get DNS hostnames; otherwise, they do not.

Command::

  aws ec2 describe-vpc-attribute --vpc-id vpc-a01106c2 --attribute enableDnsHostnames

Output::

  {
      "VpcId": "vpc-a01106c2",
      "EnableDnsHostnames": {
          "Value": true
      }
  }
