By default, the DNS page displays all primary zones in the system regardless of authority.
The left sidebar offers several options for filtering and organizing zones. At the bottom of the sidebar, you can select a filter to display: Menu, Folders, and DNS services.
- Menu provides the most commonly used filtering options for zones, such as zone types, favorites, and reverse zones.
- Folders allow you to organize zones and filter queries into folders. For more information about folder management, refer to Organizing objects with folders.
- DNS services allows you to view zones by server/service. This can be useful if you have multiple DNS services and want to view the zones associated with each one separately.
DDI orchestrator will remember your current view selection when you navigate away from the DNS page and return to it later.
Zone contents
For each zone in the DNS list, you can view its properties, details, and resource records.
The Inspector on the right side of the screen provides an overview of the Start of Authority (SOA) record and properties of the selected zone.
Select the header of the desired Inspector section, such as Properties, to collapse or expand it.
Viewing SOA records
The SOA record contains the following data fields. To edit SOA information,
select the pencil icon 
in the section header.
| Field | Description |
|---|---|
| Primary | The name of the server that serves as the primary server for the zone. |
| Hostmaster | The email address of the individual responsible for the zone,
formatted with a period (.) in place of the @ symbol. For
example, hostmaster@example.com should be
entered as hostmaster.example.com. The username
must not contain a literal dot (.). For more information, refer
to RFC-1912 "Common DNS Operational and Configuration Errors",
Section 2.2. |
| Serial | A ten-digit number representing the year, month, day, and a two-digit daily revision number. It is actually any integer between 0 and approximately 4 billion, but the aforementioned format is the standard convention. |
| Refresh | The interval, in seconds, at which secondary servers verify whether their zone files are up to date by checking the serial number against the primary server. The standard setting for this field is 28800 seconds, or every 8 hours. |
| Retry | The time a secondary server will wait to attempt reconnection with the primary zone after a failed attempt. The standard setting is 7200 seconds, or every 2 hours. |
| Expire | The duration a secondary server will continue to serve a zone following the last successful contact with the primary name server. After expiration, the secondary server stops providing information about the zone, considering it unreliable. The standard expiration time is 604800 seconds, or 1 week. |
| Neg. caching | This field is only available when connected to a BIND server. It specifies how long a server will cache the knowledge negative reponses. The standard setting is 86400 seconds, or 24 hours. |
Viewing network associations
When you select a private zone in the data grid, the Inspector displays its cloud network associations. These network associations can be changed by editing the zone options. For instructions on editing zone options for private zones, refer to Editing private zone options.
Viewing resource records
To view the DNS resource records for a particular zone, either double-click the zone in the DNS list or select it and then select Open either on the task bar or the ellipses menu in the row. A list of the zone's resource records is displayed. For more information about DNS resource records, refer to DNS resource records.
Viewing DNS zone history
To open the History dialog and view a log of all changes that have been made to a selected zone, use the Action or ellipses in the row to select View history. The history includes the following information:
- Date and time of the change
- Name of the user who made the change
- Description of the actions performed
- Comments entered by the user when saving changes to objects
For more information, refer to Viewing object change history.
