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.
This page allows you to manually configure the router’s DNS settings.
