**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}"
