DNS Proxy

Domain Name System (DNS) provides end users with the ability to look for devices or web sites by typing
their names, rather than IP addresses. For web surfers, this technology allows you to enter the URL (Univer-
sal Resource Locator) as text to surf to a desired website.
The Motorola Netopia® DNS Proxy feature allows the LAN-side IP address of the Gateway to be used for
proxying DNS requests from hosts on the LAN to the DNS Servers configured in the gateway. This is accom-

LAN.
NOTE:
The Motorola Netopia® DNS Proxy only proxies UDP DNS queries, not TCP DNS queries.

up, use any LAN attached PC or workstation running a common web browser application to configure and
monitor the Gateway.

Diagnostics

from your Web browser.
Two of the facilities are:

Gateway, from the physical connections to the data traffic.
Network Test Tools

waiting for a reply.
NSLookup - converts a domain name to its IP address and vice versa.
link initiates a sequence of tests. They examine the entire functionality of the
