+
+# Data Source: azurerm_public_ip_prefix
+
+Use this data source to access information about an existing Public IP Prefix.
+
+## Example Usage (reference an existing)
+
+```hcl
+data "azurerm_public_ip_prefix" "test" {
+  name                = "name_of_public_ip"
+  resource_group_name = "name_of_resource_group"
+}
+
+output "public_ip_prefix" {
+  value = "${data.azurerm_public_ip_prefix.test.ip_prefix}"
+}
+```
+
+## Argument Reference
+
+* `name` - (Required) Specifies the name of the public IP prefix.
+* `resource_group_name` - (Required) Specifies the name of the resource group.
+
+## Attributes Reference
+
+* `name` - The name of the Public IP prefix resource.
+* `resource_group_name` - The name of the resource group in which to create the public IP.
+* `location` - The supported Azure location where the resource exists.
+* `sku` - The SKU of the Public IP Prefix.
+* `prefix_length` - The number of bits of the prefix.
+* `tags` - A mapping of tags to assigned to the resource.
