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 NIOS-X Server called server1.infoblox.com contains two A records and an ALIAS (which is a host NIOS-X Server naming convention for CNAME records). If you view the infoblox.com zone using the hierarchical view option, you will see one entry host NIOS-X Server for server1.infoblox.com. In the flat view, you will see three records (one for each IP address/A record, and one host NIOS-X Server Alias for the CNAME).

- From the Cloud Services Infoblox Portal, click Manage -> DNS -> Configure > Networking > DNS > Zones.
