Note
From NIOS-9.x release, IB-4030 and IB-4030-10GE appliances are not supported.
Similar features are available with software based DNS cache appliances, and their respective DNS cache acceleration CLI commands.
You can configure forward and stub zones on an IB-4030 or IB-4030-10GE appliance. A forward zone is where queries are sent before being forwarded to other remote name servers. A stub zone contains records that identify the authoritative name servers in another zone. For information about configuring forward and stub zones, refer to the Configuring Delegated, Forward, and Stub Zones section in the Infoblox NIOS Administrator Guide.
