DNS Configuration

Domain Name Service (DNS) is a service used on the Internet for resolving fully
qualified domain names (FQDN) to their Internal Protocol (IP) address. You can type the

preferred DNS server IP address,

Alternative DNS server IP address that provided by ISP

or automatically assigned by ISP. Click

Submit

and

Save Settings

to save your setting.

The

DNS Configuration

page allows users to set the configuration of DNS proxy.

The firmware supports the DNS proxy function. For the DHCP requests from local
PCs, the DHCP server will set the LAN port IP as the default DNS server. Thus, all
DNS query messages will come into LAN port first. The DNS proxy on the ADSL
modem recorded the available DNS servers, and forward DNS query messages to one
of DNS server.
