5.2.10 DNS
Domain name system (DNS) is an Internet service that translates domain names
into IP addresses. Because domain names are alphabetic, they are easier to
remember. The Internet, however, is actually based on IP addresses. Each time you
use a domain name, a DNS service must translate the name into the corresponding
IP address. For example, the domain name www.example.com might be translated
to 198.105.232.4.
The DNS system is, in fact, its own network. If one DNS server does not know how
to translate a particular domain name, it asks another one, and so on, until the
correct IP address is returned.
Choose Advanced > DNS . The page shown in the folllowing figure appears.
If you are using the device for DHCP service on the LAN or using DNS servers on
the ISP network, select Obtain DNS server address automatically .
If you have DNS IP addresses provided by your ISP, select Use the following DNS
server addresses , and enter these IP addresses in the available entry fields for the
preferred DNS server and the alternate DNS server.
Click Apply to save the settings.
