DNS zones are organized within a DNS View. From the Cloud Services Infoblox Portal, click ManageConfigure > Networking -> DNS -> Zones. All existing views are shown under All DNS Views. If there are multiple views, you must click the particular DNS view to drill down to view the zones and subzones. If there are no DNS views, you must create them before adding a zone. For more information about creating a DNS view, see Configuring DNS Views.

A primary zone stores the master copy of the zone data. A secondary zone is a read-only copy of the primary zone that is stored on a different server. The secondary zone cannot process updates and can only retrieve updates from the primary zone. The secondary zone can answer DNS name resolution queries from client nodes, which helps reduce the workload on the primary zone. When you want to forward queries for data in a particular zone, define the zone as a forward zone and specify one or more DNS servers, a hostNIOS-X Server, or an IP address that can resolve queries for the zone.

A primary zone on BloxOne Universal DDI (cloud) is an authoritative zone. |
...
You can configure and manage authoritative forward-mapping and IPv4 reverse-mapping zones on the Infoblox BloxOne Universal DDI cloud service portal. When you create an authoritative forward-mapping zone or reverse-mapping zone, you assign zone authority to a DNS server and define it as the primary server for the zone. A primary server is designated as the primary source for the zone and maintains a master copy of the zone data.
You can also create one or more secondary DNS servers for a zone. A secondary server for a zone receives read-only zone data from the primary server. If a zone is part of an internal DNS structure for a private network, the inclusion of a secondary DNS server is optional, though highly recommended. If a zone is a part of an external DNS structure for a public network such as the Internet, then a secondary server in a different subnet from the primary server is required. This requirement provides an additional safeguard against localized network failures causing both primary and secondary DNS servers for a zone to become inaccessible.
You can specify the primary and secondary server for a zone or you can specify a DNS server group. A DNS server group is a collection of one or more primary servers and one or more secondary servers. For information on DNS server groups, see Configuring DNS Server Groups.
The following is an example of an IPv4 reverse-mapping zone hierarchy:
