Disable IPv6 Networking if not in use within your organization¶

Any protocols enable within Lightsail by default that aren't being used should be disabled.

How to fix¶

Attribute ip_address_type of aws_lightsail_instance must be "ipv4".

Implementation options¶

Choose the option that matches how you manage Terraform. All options satisfy this control.

Option 1: Terraform AWS provider resources¶

If you manage resources directly, configure the relevant Terraform AWS provider resources to meet this control. See docs for the resources involved: aws_lightsail_instance.

resource "aws_lightsail_instance" "this" {
  availability_zone = local.availability_zone
  blueprint_id      = "amazon_linux_2"
  bundle_id         = "nano_3_0"
  name              = "pofix-example-lightsail"

  ip_address_type = "ipv4"
}

Which option should I choose?

Compliance.tf module (recommended): controls enforced by default and mapped to frameworks.
Open source module (terraform-aws-modules): compatible by design with compliance.tf. Same variable names for an easy, low-change migration path when you are ready.
Terraform AWS provider resources: manage Terraform resources directly.
