+    Provides a list of network interface ids
+---
+
+# Data Source: aws_network_interfaces
+
+## Example Usage
+
+The following shows outputing all network interface ids in a region.
+
+```hcl
+data "aws_network_interfaces" "example" {}
+
+output "example" {
+  value = "${data.aws_network_interfaces.example.ids}"
+}
+```
+
+The following example retrieves a list of all network interface ids with a custom tag of `Name` set to a value of `test`.
+
+```hcl
+data "aws_network_interfaces" "example" {
+  tags {
+    Name = "test"
+  }
+}
+
+output "example1" {
+  value = "${data.aws_network_interfaces.example.ids}"
+}
+```
+
+The following example retrieves a network interface ids which associated
+with specific subnet.
+
+```hcl
+data "aws_network_interfaces" "example" {
+  filter {
+    name = "subnet-id"
+    values = ["${aws_subnet.test.id}"]
+  }
+}
+
+output "example" {
+  value = "${data.aws_network_interfaces.example.ids}"
+}
+```
+
+## Argument Reference
+
+* `tags` - (Optional) A mapping of tags, each pair of which must exactly match
+  a pair on the desired network interfaces.
+
+* `filter` - (Optional) Custom filter block as described below.
+
+More complex filters can be expressed using one or more `filter` sub-blocks,
+which take the following arguments:
+
+* `name` - (Required) The name of the field to filter by, as defined by
+  [the underlying AWS API](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeNetworkInterfaces.html).
+
+* `values` - (Required) Set of values that are accepted for the given field.
+
+## Attributes Reference
+
+* `ids` - A list of all the network interface ids found. This data source will fail if none are found.
