Below terraform code showing most of the details of instances in a region. Even subnet id showing but not vpc id.

> provider “aws” {  
> region = “us-west-1”  
> }
> 
> data “aws\_instances” “instances” {  
> instance\_state\_names = [“running”, “stopped”,“pending”, “shutting-down”, “stopping”] #, “terminated”]  
> }
> 
> data “aws\_instance” “this” {  
> for\_each = toset(data.aws\_instances.instances.ids)  
> instance\_id = each.key  
> }  
> output “instance\_arns” {  
> value = data.aws\_instance.this[\*]  
> }

How to retrieve vpc id also?

Hi @uday-globuslive,

In the EC2 API there is no direct relationship between EC2 instance and VPC: an EC2 instance’s network interface belongs to one subnet and then each subnet belongs to one VPC.

Once you have a subnet ID, you can find the VPC it belongs to using [the `aws_subnet` data source](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/subnet) and then accessing the `vpc_id` attribute of the resulting object.

Could you please help how to implement that in above code.
