DNS stands for Domain Name System. Every Internet host
must have a unique IP address, also they may have a
human-friendly, easy to remember name such as
www.yahoo.com. The DNS server converts the user-friendly
name into its equivalent IP address.
Primary IP Address -You must specify a DNS server IP address
here because your ISP should provide you with usually more
than one DNS Server.
Secondary IP Address - You can specify secondary DNS server
IP address here because your ISP often provides you more
than one DNS Server.
The default DNS Server IP address can be found via Online
Status:
If both the Primary IP and Secondary IP Address fields are left
empty, the router will assign its own IP address to local users
as a DNS proxy server and maintain a DNS cache.
If the IP address of a domain name is already in the DNS
cache, the router will resolve the domain name immediately.
Otherwise, the router forwards the DNS query packet to the
external DNS server by establishing a WAN (e.g. DSL/Cable)
connection.
Force router to use address for DNS- Force Vigor modem to
use DNS servers in this page instead of DNS servers given by
the Internet Access server (PPPoE, PPTP, L2TP or DHCP
server).
