CHAPTER 7
DNS Route
7.1 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 LTE Device 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 LTE Device receives a DNS reply from a DNS server, it
creates a new entry for the resolved IP address in the routing table.

The DNS Route screens let you view and configure DNS routes on the LTE Device (Section 7.2 on
page 60).
