Domain administrator email address
The email address defaults to the user name “admin” of the Qube 3. This email
address is publicly available and is the administrative contact for the domain or
network served.
Refresh interval
You can configure the refresh interval between updates from a secondary DNS
server.
• If DNS record changes occur infrequently, increase the default value.
• If DNS record changes occur often, decrease the default value.
Tune the refresh interval to avoid wasting bandwidth and to ensure the content on
the secondary server is accurate at all times.
