+# Google Cloud DNS Inbound Policy Addresses
+
+This module allows discovering the addresses reserved in subnets when [DNS Inbound Policies](https://cloud.google.com/dns/docs/policies) are configured.
+
+Since it's currently impossible to fetch those addresses using a GCP data source (see [this issue](https://github.com/hashicorp/terraform-provider-google/issues/3753) for more details), the workaround used here is to derive the authorization token from the Google provider, and do a direct HTTP call to the Compute API.
+
+## Examples
+
+```hcl
+module "dns-policy-addresses" {
+  source          = "./modules/_experimental/net-dns-policy-addresses"
+  project_id      = "myproject"
+  regions = ["europe-west1", "europe-west3"]
+}
+# tftest skip
+```
+
+The output is a map with lists of addresses of type `DNS_RESOLVER` for each region specified in variables.

+|---|---|:---:|:---:|:---:|
+| [project_id](variables.tf#L17) | Project id. | <code>string</code> | ✓ |  |
+| [regions](variables.tf#L22) | Regions to fetch addresses from. | <code>list&#40;string&#41;</code> |  | <code>&#91;&#34;europe-west1&#34;&#93;</code> |
