All zones reside within a DNS view. You can create multiple DNS views and create zones within each DNS view. If there is only one DNS view, the zones in the view are displayed automatically. If there are multiple DNS views, you must click the particular DNS view to view the zones. You can associate an IP space with a DNS view, so all DNS records can be automatically listed as related objects in the corresponding subnets.
In the hierarchical view, the sub-zones are nested within the zone in a hierarchical structure. In the flat zone view, you can view the zones, including the nested ones in a single list. For example, the host called server1.infoblox.com contains two A records and an ALIAS (which is a host naming convention for CNAME records). If you view the infoblox.com zone using the hierarchical view option, you will see one entry host for server1.infoblox.com. In the flat view, you will see three records (one for each IP address/A record, and one host Alias for the CNAME).
To view the list of zones in the flat zone view, complete the following:
- From the Cloud Services Portal, click Manage -> DNS -> Zones.
- Toggle Flat Zone View to ON.
- BloxOne DDI displays the following information for all zones and subzones as a single list:
