DNS Route
10.1 Overview
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and
vice versa. The DNS server is extremely important because without it, you must know the IP address
of a machine before you can access it.
In addition to the system DNS servers, each WAN interface (service) is set to have its own static or
dynamic DNS server list. You can configure a DNS static route to forward DNS queries for certain
domain names through a specific WAN interface to its DNS servers. The Router uses a system DNS
server (in the order you specify in the
Broadband
screen) to resolve domain names that do not
match any DNS routing entry. After the Router receives a DNS reply from a DNS server, it creates a
new entry for the resolved IP address in the routing table.
10.2 The DNS Route Screen
The
DNS Route
screens let you view and configure DNS routes on the Router. Click
Network
Setting > Routing > DNS Route
to open the
DNS Route
screen. A DNS route forwards DNS queries
for a specific domain name through a specific WAN interface to its DNS server.
