6.3 DNS
A Domain Name System (DNS) server is like an index of IP addresses and Web addresses. If
you type a Web address into your browser, such as www.router.com, a DNS server will find
that name in its index and the matching IP address. Most ISPs provide a DNS server for
speed and convenience. If your Service Provider connects you to the Internet with dynamic
IP settings, it is likely that the DNS server IP address is provided automatically. However, if
there is a DNS server that you would rather use, you need to specify the IP address of that
DNS server here.
Parameters Description
Domain Name Server (DNS) Server This is the ISP’s DNS server IP address that they
gave you; or you can specify your own preferred
DNS server IP address
Secondary DNS Address (optional) This is optional. You can enter another DNS
server’s IP address as a backup. The secondary
DNS will be used should the above DNS fail.
