You now have the ability to switch between BIND or Unbound resolvers on IB-4030-10GE appliances. Following are a couple scenarios for which you may consider using Unbound DNS resolution:
...
To use Unbound DNS, you must install the Dual Engine DNS license (in addition to the DNS Cache Acceleration license) on your IB-4030-10GE appliance. Contact your Infoblox representative to obtain these licenses. For information about how to install licenses, refer to the Infoblox NIOS Administrator GuideNIOS documentation at docs.infoblox.com..
| Note | ||

| ||
When the Dual Engine DNS license (either temporary or permanent) expires, you will not be able to change the resolver type from Unbound to BIND. You must install a permanent license or extend the current license in order to change the resolver type. |
...
- There might be a few known general issues when configuring Unbound DNS resolution. Refer to the latest version of the NIOS 7.2.x release notes to review these issues For a list of supported platforms for each NIOS release, please see the NIOS Release Notes for that release. The Release Notes are available on the Infoblox Support portal at https://support.infoblox.com.
Configuring DNS Resolver Type
...
Unbound DNS supports the configuration of hostname bind directive and server-id directive options, which enables the appliance to return the hostname of the answering DNS name server in response to queries from clients in a DNS anycast configured environment. For information about how to configure the hostname bind directive and server-id directive options, refer to the Configuring Hostname and Server ID Options section in the Infoblox NIOS Administrator GuideNIOS documentation at docs.infoblox.com.

Even though you can configure both hostname bind directive and server-id directive options, Unbound DNS ignores the hostname bind directive setting and considers only the server-id directive setting. |
