• 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.pentagram.eu 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.
