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.yahoo.com and an IP address. An IP address is a 32-bit number in the form of 
xxx.xxx.xxx.xxx, for example 192.168.1.254. You can think of an IP address as a telephone 
number for devices on the Internet, and the DNS allows you to find the telephone number for 
any particular domain name. Since 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. Usually when you choose PPPoE or PPPoA as your WAN - ISP 
protocol, the ISP provides 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. 
 

 

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