DNS Server Settings
The
DNS Server
on the Quadro provides the services to the hosts in the Quadro’s LAN. With this service, Quadro returns the correct IP address to
the requested domain name, so that any device in the LAN can be accessed by its hostname or alternative alias name.
The
DNS Server Settings
page is used to configure DNS server settings on the Quadro and to define a list of aliases for the devices in the Quadro’s
LAN. This page contains the following components:
Zone
field displays the Quadro’s host domain name as it is
configured in the
Time to live (TTL)
text field indicates the time (in seconds)
during which the DNS server will keep the resolved names in its
cache. During this time the same address will be resolved from
the cache of the DNS server. When this timeout expires, the
requested address will be resolved newly.
Mail Exchange (MX)
text field indicates the mail server’s
hostname. When resolving the email address, the reference will
go to the mail server defined in this field, before being sent out
to the external network. The value in this field will be used in the
MX record in the DNS server on the Quadro.
The table on this page lists aliases for each of the device in the
Quadro’s LAN to be resolves through the DNS server.
