    10  
    11  `aws_prefix_list` provides details about a specific prefix list (PL)
    12  in the current region.
    13  
    14  This can be used both to validate a prefix list given in a variable
    15  and to obtain the CIDR blocks (IP address ranges) for the associated
    16  AWS service. The latter may be useful e.g. for adding network ACL
    17  rules.
    18  
    19  ## Example Usage
    20  
    21  ```hcl
    22  resource "aws_vpc_endpoint" "private_s3" {
    23    vpc_id       = "${aws_vpc.foo.id}"
    24    service_name = "com.amazonaws.us-west-2.s3"
    25  }
    26  
    27  data "aws_prefix_list" "private_s3" {
    28    prefix_list_id = "${aws_vpc_endpoint.private_s3.prefix_list_id}"
    29  }
    30  
    31  resource "aws_network_acl" "bar" {
    32    vpc_id = "${aws_vpc.foo.id}"
    33  }
    34  
    35  resource "aws_network_acl_rule" "private_s3" {
    36    network_acl_id = "${aws_network_acl.bar.id}"
    37    rule_number    = 200
    38    egress         = false
    39    protocol       = "tcp"
    40    rule_action    = "allow"
    41    cidr_block     = "${data.aws_prefix_list.private_s3.cidr_blocks[0]}"
    42    from_port      = 443
    43    to_port        = 443
    44  }
    45  ```
    46  
    47  ## Argument Reference
    48  
    49  The arguments of this data source act as filters for querying the available
    50  prefix lists. The given filters must match exactly one prefix list
    51  whose data will be exported as attributes.
    52  
    53  * `prefix_list_id` - (Optional) The ID of the prefix list to select.
    54  
    55  * `name` - (Optional) The name of the prefix list to select.
    56  
    57  ## Attributes Reference
    58  
    59  The following attributes are exported:
    60  
    61  * `id` - The ID of the selected prefix list.
    62  
    63  * `name` - The name of the selected prefix list.
    64  
    65  * `cidr_blocks` - The list of CIDR blocks for the AWS service associated
    66  with the prefix list.
