Use the OneFuse DNS module to manage DNS policies by [Endpoint](/docs/onefuse/configure/module-endpoints/) Type using the DNS dashboard.

<div class="alert alert-info" role="alert"><div class="h4 alert-heading" role="heading">Prerequisites</div>


Create a [Module Credential](/docs/onefuse/configure/module-credentials/) and Endpoint for the selected technology.
</div>


1. In OneFuse, select **DNS** from **Home**, or select **Modules** > **DNS** from the left navigation menu.
2. Create a DNS Policy for a supported technology.
3. Reserve and release DNS records through the OneFuse API or an [Upstream Provider](/docs/onefuse/consume/what-is-upstream-provider/).
4. View Managed DNS Records generated from DNS policy executions.

## DNS defaults

DNS defaults can be set up at the Endpoint level. Network Views can be set up for different use cases and can include templated values. Every DNS Policy execution for an Endpoint with defaults will use those defaults.

## Managed DNS records

Use the Managed DNS Records dashboard to review DNS records reserved by executing a DNS Policy.

1. Select **DNS** from the OneFuse Modules menu.
2. Go to the **Managed DNS Records** dashboard.

OneFuse supports asynchronous calls to DNS. To view job status, see the API.

## DNS policy form

| Field | Description |
| --- | --- |
| **DNS Policy Name** | Enter a name for this DNS Policy. |
| **Description** | Optional description for this DNS Policy. |
| **General** | |
| **Endpoint Type** | Select the Endpoint Type for this DNS Policy. |
| **Endpoint** | Select the desired OneFuse Endpoint. |
| **Record settings** | |
| **Record Type** | Select at least one Record Type based on your needs. |
| **Create A Record** | Select the toggle to resolve an FQDN to an IP address. |
| **Create PTR Record** | Select the toggle to resolve an IP address to an FQDN. |
| **Create CNAME Record** | Select the toggle to create a CNAME record. Creating a CNAME record is mutually exclusive with creating Host (Infoblox), A, and PTR records. During `POST /dnsReservation` for a CNAME DNS Policy, provide the CNAME (A Record) as the value of the body field `value`. See example below. |
| **Validation settings** | |
| **Post-Validation Sleep Seconds** | Enter the number of seconds to sleep before post-validating DNS entries. Templatable field. |
| **DNS Validation Timeout Seconds** | Enter a value in seconds after which DNS validation will timeout. Templatable field. |
| **Advanced** | |
| **Hostname Override** | Optional. Enter a Hostname Override. The variable is `{{request.hostname}}`. If no hostname override is desired, use the default value. |

<div class="alert alert-info" role="alert">


Recommend having one DNS Policy for Host (Infoblox), A, and/or PTR records, and a separate DNS Policy for CNAME records.
</div>


CNAME DNS reservation example:

```json
{
  "name": "<Hostname (shortname)>",
  "value": "<CNAME A Record Value (FQDN)>",
  "zones": ["example.com", "example.io"],
  "policy": "/api/v3/onefuse/dnsPolicies/<dnsPolicyId>/",
  "workspace": "{{workspaceUrl}}",
  "templateProperties": {}
}
```
