Configuring DNS Relay
This chapter describes how to configure DNS (Domain Name System) Relay on your Prestige.
19.1 Overview
An IP address uniquely identifies a host on the Internet. Since IP addresses are difficult to remember, a
user-friendly domain name is used often instead. A domain name is a unique name that identifies an
Internet site. The Domain Name System (DNS) maps a domain name to an IP address. When you access a
web site, you can type either the IP address or the domain name. As your LAN computers access the
Internet, domain names are converted to IP addresses on the DNS server.
With your Prestige configured as a DNS relay server, Internet access requests received from the LAN
computers will be forwarded to the actual DNS servers at your ISP.
19.2 Viewing Your DNS Relay Setup
To view your current DNS relay configuration, launch the web configurator, click Services and DNS to
display the DNS Configuration screen. DNS relay is enabled by default.
