You can specify a network server to perform domain name queries and specify up to two name servers for resolving a DNS name. You can specify the IP address of a preferred name server and that of an alternate name server, plus use a search list for performing partial name resolution.
To enable DNS resolution for a Grid or for an independent appliance or HA pair:
In the GridProperties or MemberProperties editor, select the DNSResolver tab, and then enter the following:
Enable DNS Resolver: Select the check box to enable the NIOS appliance to send DNS queries to the preferred or alternate name servers whose IP addresses you specify in the following fields.Click the Add icon and enter the IP addresses (IPv4 or IPv6) of the servers to which the appliance sends queries. The first address that you add is the primary DNS resolver and the second address that you add is the secondary DNS resolver. The appliance attempts to send queries to the servers in the order they are listed if it does not receive a response from a listed name server. To move a server up or down on the list, select it and drag it to its new location or click the up and down arrows.
If you are using the Infoblox Subscriber Parental Control feature, set the primary DNS resolver to a loopback address (127.0.0.1) to enable parental control.
