3.6.3.2.2 DNS
A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. In the Internet, every host has a unique and friendly name such as www.yahoo.com and an IP address. As the 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 provides it when you logon. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the ISP will provide the DNS IP address automatically. You may leave it as blank. Or your ISP may provide you with an IP address of their DNS. If this is the case, you must enter the DNS IP address.
