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}"
