Modifying a VPC Attribute
You can modify an attribute of a Virtual Private Cloud (VPC), either to enable or disable support for DNS servers, or to enable or disable DNS hostnames.
The DNS servers for the VPC are defined in a set of DHCP options. When you create a VPC, a default set of DHCP options is created and automatically associated with the VPC, but you can replace it with a custom set. For more information, see About DHCP Options.
This feature is not available from Cockpit. This documentation only describes the procedure using AWS CLI.
To modify an attribute of a VPC, use the modify-vpc-attribute command following this syntax:
$ aws ec2 modify-vpc-attribute \ --profile YOUR_PROFILE \ --vpc-id vpc-12345678 \ --no-enable-dns-support \ [--enable-dns-hostnames | --no-enable-dns-hostnames] \ --endpoint https://fcu.eu-west-2.outscale.com
This command contains the following attributes that you need to specify:
profile: The named profile you want to use, created when configuring AWS CLI. For more information, see Installing and Configuring AWS CLI.
vpc-id: The ID of the VPC.
no-enable-dns-support: If set to
enable-dns-support, the DNS servers for the VPC resolve DNS hostnames for your instances to the corresponding IPs. If set to
no-enable-dns-support, they do not.
no-enable-dns-hostnames: If set to
enable-dns-hostnames, instances launched in the VPC get DNS hostnames. If set to
no-enable-dns-hostnames, they do not.
You cannot modify both the DNS support attribute and the DNS hostnames attribute at the same time. To modify the two attributes, use two separate requests.
endpoint: The endpoint corresponding to the Region you want to send the request to.
The specified attribute is modified.
