DNS
DNS Server
DNS (Domain Name System) is an Internet service that translates domain names into IP addresses.
Because domain names are alphabetic, they are easier to remember. However, the Internet is based
on IP addresses. Therefore, each time you type a domain name, a DNS service must translate the
name into the corresponding IP address. For example, the domain name www.example.com might
translate to 198.105.232.4. The DNS system consists of a network of DNS servers. 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 select the Enable Automatic Assigned DNS checkbox, the router will receive and use the DNS
Server assigned by your ISP.
To use your preferred DNS servers, disable the Enable Automatic Assigned DNS checkbox and key in
the IP address of your Primary DSN server. Adding a Secondary DNS server is optional.
