+# google\_compute\_global\_address
+
+Get the IP address from a static address reserved for a Global Forwarding Rule which are only used for HTTP load balancing. For more information see
+the official [API](https://cloud.google.com/compute/docs/reference/latest/globalAddresses) documentation.
+
+## Example Usage
+
+```hcl
+data "google_compute_global_address" "my_address" {
+  name = "foobar"
+}
+
+resource "google_dns_record_set" "frontend" {
+  name = "lb.${google_dns_managed_zone.prod.dns_name}"
+  type = "A"
+  ttl  = 300
+
+  managed_zone = "${google_dns_managed_zone.prod.name}"
+
+  rrdatas = ["${data.google_compute_global_address.my_address.address}"]
+}
+
+resource "google_dns_managed_zone" "prod" {
+  name     = "prod-zone"
+  dns_name = "prod.mydomain.com."
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) A unique name for the resource, required by GCE.
+
+- - -
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `self_link` - The URI of the created resource.
+* `address` - The IP of the created resource.
+* `status` - Indicates if the address is used. Possible values are: RESERVED or IN_USE.
