DNS

This page allows you to manually configure the router's DNS settings.
Domain Name System (DNS) is an Internet service that translates domain names into IP
addresses. Because domain names are alphanumeric, 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.
If you are using the device for DHCP service on the LAN or if you are using DNS servers on
the ISP network, select Obtain DNS Info from a WAN interface.
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 of the Preferred DNS
server and the Alternate DNS server.
Click Apply when you are done.
