In order to use your new vNIOS appliance for DNS and discovery of resources in Azure, you will need to enable some basic services, Network Time Protocol (NTP), and Domain Name System (DNS).

Start the NTP Service

  1. Log back in to Grid Manager.

  2. Navigate to the Grid → Grid Manager tab.

  3. Click on NTP in the Services bar.

  4. Select the checkbox next to your Grid Master.

  5. Click the start button to start the NTP service.

  1. Click Yes in the warning window.

Start and Configure DNS Service

  1. Click on DNS in the Services bar.

  2. Select the checkbox next to your Grid Master.

  3. Click the start button to start the DNS service.

  1. Click Yes in the warning window.

  1. From the Toolbar on the right, use the Edit dropdown to select Grid Properties.

  1. In the Grid Properties Editor, select the DNS Resolver page.

  2. Click the check box for Enable DNS Resolver.

  3. Click the add button and enter the IP of an upstream name server. This can be the default Azure resolver, 168.63.129.16, or a name server of your choosing. This resolver is used by NIOS to resolve names used by services in the Grid. For example, this will be used to resolve the Azure API endpoint used for vDiscovery.

Create a DNS Zone

To enable automatic creation of DNS records when using vDiscovery for Azure, the Infoblox grid must be authoritative for at least one DNS Zone. To create a DNS zone in Grid Manager:

  1. In the Grid Manager, navigate to Data Management →  DNS → Zones.

  2. Use the add zone dropdown to select Authoritative Zone.

  1. In the Add Authoritative Zone Wizard, select Add an authoritative forward-mapping zone.

  2. Click Next.

  1. Enter the name of your zone and click Next.

  1. On Step 3, select Use this set of name servers.

  2. Click the icon and select Grid Primary from the dropdown.

  1. Click Select in the Add Grid Primary panel.

  1. For a Grid with only one member, it will be automatically selected. If your Grid has multiple members, select the one you want to use as the primary for this zone.

  2. Click Add.

  1. Click Save & Close.

  1. Click Restart in the warning bar when prompted.

  1. Click Restart in the Restart Grid Services window.
