DNS Configuration
A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the Internet,
every host has a unique and user-friendly name (domain name) such as www.helloworld.com and an IP address.
An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx, for example 192.168.1.1. You can think of an IP
address as a telephone number for devices on the Internet, and the DNS will allow you to find the telephone
number for any particular domain name. As an IP Address is hard to remember, the DNS converts the friendly
name into its equivalent IP Address.

You can obtain a Domain Name System (DNS) IP address automatically if your ISP has provided it when you
logon, check the Enable box. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the ISP
will provide the DNS IP address automatically. You may leave the configuration field blank.
Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you must enter the
DNS IP address manually
