DNS
A Domain Name System (DNS) contains a mapping table for domain name and IP address. In the Internet, every host has a
unique and friendly name such as www.yahoo.com and IP address. The IP address is very hard to remember, so that you
may just enter the friendly name www.yahoo.com and DNS converts it to its equivalent IP address.
You can obtain Domain Name System (DNS) IP address automatically if ISP provides it when you logon. This Obtain DNS
address automatically selection is set as default when you choose PPPoE or PPPoA as your WAN - ISP protocol. Or your
ISP may provide you with an IP address of DNS. If this is the case, you must enter the DNS IP address.
Moreover, if you set RFC1483, IPoA, or PPTP-to-PPPoA Relaying as your WAN-ISP protocol, you can only enter the DNS IP
Address as below figure instead of obtaining the address automatically.
