In a reverse-mapping zone, a PTR (pointer) record maps an IP address to a NIOS-X Server name. Before adding a PTR record to a reverse-mapping zone, you must first create the zone. You can also add PTR records to forward-mapping zones to support zeroconf (zero configuration networking), such as wide-area Bonjour. For information about the Bonjour protocol, refer to *[http://www.apple.com/support/bonjour](http://www.apple.com/support/bonjour)*. Though adding PTR records to forward-mapping zones supports some of the use cases in RFC 1101, it does not support the network name mapping use case described in the RFC. For more information, refer to *[http://tools.ietf.org/html/rfc1101](http://tools.ietf.org/html/rfc1101)*.
To create a PTR Record, complete the following:
1. From the Infoblox Portal, click **Network > DNS > Zones**.
2. Click the DNS view.
3. Click the zone.
4. Click **Create **>** Record **and select **PTR Record **from the drop-down list.
On the *Create PTR Record *page, select or specify the following and click **Save & Close**:
> Macro (excerpt)
>
> - **Address**: Enter the owner name of the PTR Record, in the form of either an IP address or a name.
> - **Select Zone**: Select an associated zone from the column selector.
> - **Domain Name: **Enter the domain name record data for the PTR Record.
> - **Record Protection**: The record protection options are only displayed when you modify a resource record. The option to enable record protection is also only visible when you are the Global Admin or are a DDI Admin. For detailed information about this feature, see *[DNS Record Protection](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneDDI/pages/2056815453)*. Choose one of the following options for the role-based access control:
> - **None**: Choose this option if you do not want any protection for this record. If you choose this option, any user can modify this record.
> - **Global Admin Only**: Only the Global Admin will be able to modify this record. If a DDI Admin or a non-admin views this record, the fields will be greyed out and they will not be able to modify this record.
> - **DDI Admin Only**: Only the DDI Admin and the Global Admin will be able to modify this record. If a non-admin views this record, the fields will be greyed out and they will not be able to modify this record.
> - **Description**: Enter a descriptive comment about the PTR Record.
> - **TTL**: Enter a numeric value and select Hours, Minutes, or Seconds from the drop-down.
> - **Disable for DNS Protocol**: Click this check box to temporarily disable for DNS Protocol.
> - **Tags**: Click **Add** to associate keys with values. Specify the following details:
> - **KEY**: Enter a meaningful name for the key, such as a location or a department.
> - **VALUE**: Enter a value for the key such as San Jose (for location), or Accounts (for department).
> - To remove a tag, select the respective check box and click **Remove** to delete the associated tag. For more information about tags, see *[Managing Tags](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneDDI/pages/186745865)*.
> ⚠️ Record data fields that are domain names (such as "Canonical Name" of CNAME or "Domain Name" of PTR) can be either relative (to the zone name) or absolute. The value of those fields must therefore be explicitly ended with a period if they are intended to be absolute. Otherwise, the zone name will be appended to the user-supplied name to be absolute.
