# aws\_ip_ranges

Use this data source to get the [IP ranges][1] of various AWS products and services.

## Example Usage

```
data "aws_ip_ranges" "european_ec2" {
  regions = [ "eu-west-1", "eu-central-1" ]
  services = [ "ec2" ]
}

resource "aws_security_group" "from_europe" {

  name = "from_europe"

  ingress {
    from_port = "443"
    to_port = "443"
    protocol = "tcp"
    cidr_blocks = [ "${data.aws_ip_ranges.european_ec2.cidr_blocks}" ]
  }

  tags {
    CreateDate = "${data.aws_ip_ranges.european_ec2.create_date}"
    SyncToken = "${data.aws_ip_ranges.european_ec2.sync_token}"
  }

}
```

## Argument Reference

* `regions` - (Optional) Filter IP ranges by regions (or include all regions, if
omitted). Valid items are `global` (for `cloudfront`) as well as all AWS regions
(e.g. `eu-central-1`)

* `services` - (Required) Filter IP ranges by services. Valid items are `amazon`
(for amazon.com), `cloudfront`, `ec2`, `route53` and `route53_healthchecks`.

~> **NOTE:** If the specified combination of regions and services does not yield any
CIDR blocks, Terraform will fail.

## Attributes Reference

* `cidr_blocks` - The lexically ordered list of CIDR blocks.
* `create_date` - The publication time of the IP ranges (e.g. `2016-08-03-23-46-05`).
* `sync_token` - The publication time of the IP ranges, in Unix epoch time format
  (e.g. `1470267965`).
