Changing the default downstream DNS configuration settings for a network

When you create a new network with the Create Network wizard, the network is configured to use these default downstream DNS configuration options:

Hidden master is disabled

Notify is disabled

The refresh rate is three hours

Once you have created a new network, at any time, you can use the Networks Network View page to change these default settings.

For more information about the effects of each setting and for a list of considerations for modifying each setting, see Downstream DNS configuration settings for networks.

To change the default downstream DNS configuration settings for a network:

1.On the Networks Network View page, click the name of the network for which you want to change the default downstream DNS configuration settings.

2.Take one of these actions:

oIf the Settings panel opens, go to step 4.

oIf the IP Configuration panel opens, click the Settings tab at the top of the panel to display the Settings panel.

3.On the Settings panel, click Downstream DNS Configuration to view the downstream DNS configuration settings.

4.In the Downstream DNS Configuration section:

oTo enable hidden master, select Enable hidden master.

oTo enable notify, select Enable notify.

oIf you are enabling hidden master or notify, in the Downstream DNS Servers field, type a comma-separated list of between one and ten downstream DNS server IP addresses. Spaces are not allowed.

Note: If a secondary IPv6 subnet is defined for the network, then each IPv6 address that you specify in the downstream DNS server list must either be on the secondary IPv6 subnet or be routable from the primary IPv6 gateway that’s defined for the network.

oTo change the refresh rate, in the Refresh Rate field, type the new refresh rate. For valid values for the refresh rate, see Downstream DNS configuration settings for networks.
