# ionoscloud\_lan

The **LAN data source** can be used to search for and return existing lans. If a single match is found, it will be returned. If your search results in multiple matches, an error will be returned. When this happens, please refine your search string so that it is specific enough to return only one result.

## Example Usage

### By ID

```hcl
data "ionoscloud_lan" "example" {
  datacenter_id = "datacenter_id"
  id			= "lan_id"
}
```

### By Name

```hcl
data "ionoscloud_lan" "example" {
  datacenter_id = "datacenter_id"
  name			= "Lan Example"
}
```

## Argument Reference

* `datacenter_id` - (Required) Datacenter's UUID.
* `name` - (Optional) Name of an existing lan that you want to search for.
* `id` - (Optional) ID of the lan you want to search for.

`datacenter_id` and either `name` or `id` must be provided. If none, or both of `name` and `id` are provided, the datasource will return an error.
