4.3.2.2 DNS

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.billion.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.
