DNS

A Domain Name System (DNS) contains a mapping table for mapping between Domain Names and IP addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as www.helloworld.com as well as an IP address. An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx, for example 10.0.0.2. 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 provides it when you logon. To use this automatically supplied DNS 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.

If you choose one of the other three protocols RFC1483 Routed/Bridged or IPoA, please check with your ISP as it may provide you with an IP address for their DNS server. You will need to enter the DNS IP address if you set the DNS of your PC to the LAN IP address of this router.
