Example 1: To modify the enableDnsSupport attribute

The following modify-vpc-attribute 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.

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

This command produces no output.

For more information, see View and update DNS attributes for your VPC in the Amazon VPC User Guide.

Example 2: To modify the enableDnsHostnames attribute

The following modify-vpc-attribute 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.

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

This command produces no output.

For more information, see View and update DNS attributes for your VPC in the Amazon VPC User Guide.
