Server services for the LAN
̈ Initially the router checks whether a DNS server has been entered in its
own settings. If it is successful there, it obtains the desired information
from this server. Up to two higher-level DNS servers can be specified.
̈ If no DNS server is entered in the router, it will attempt to reach a DNS
server over a PPP connection (e.g. from the Internet provider) to get the
IP address assigned to the name from there. This can only succeed if the
address of a DNS server is sent to the router during PPP negotiation.
̈ The default route is established and the DNS server searched for there if
no connection exists.
This procedure does not require you to have any knowledge of the DNS server
address. Entering the Intranet address of your router as the DNS server for the
workstation computers is sufficient to enable you obtain the name assign-
ment. This procedure also automatically updates the address of the DNS
server. Your local network always receives the most current information even
if, for example, the provider sending the address changes the name of his DNS
server or you change to another provider.
