# nebius_vpc_v1alpha1_subnet data source

#### Retrieving the Data Source

This data source can be retrieved by one of ID or name.

##### Retrieve by ID

To retrieve by ID, fill in only the `id` field:

```hcl theme={null}
data ... {
    id = "your-ID"
}
```

##### Retrieve by Name

To retrieve by name, fill in only the `name` and `parent_id` fields:

```hcl theme={null}
data ... {
    name      = "your name"
    parent_id = "data-source-parent-id"
}
```

Defines a Subnet, a segment of a network used for more granular control and management.
Subnet uses pools to organize address space.

## Schema

### Optional

* `id` (String) Identifier for the resource, unique for its resource type.
* `name` (String) Human readable name for the resource.
* `parent_id` (String) Identifier of the parent resource to which the resource belongs.

### Read-Only

* `created_at` (String) :

  Timestamp indicating when the resource was created.

  Version of the resource for safe concurrent modifications and consistent reads.
  Positive and monotonically increases on each resource spec change (but *not* on each change of the
  resource's container(s) or status).
  Service allows zero value or current.
* `status` (Attributes) Status of the subnet. (see [below for nested schema](#nestedatt--status))
