DNS Local Database
Domain Name Service (DNS) is a service that matches a domain name to its
routable IP address. You can set up a DNS Local Database that enables the router
to act as a local DNS server for commonly used domain names. Using a local
database may be faster than using an external DNS server. If a requested domain
name is not found in the local database, then the request is forwarded to the DNS
server that is specified on the
Setup > Network
page,
WAN Setting
section.
If you enable this feature, you also must configure the client devices to use the
router as the DNS server. By default, Windows computers are set to obtain a DNS
server address automatically, from the WAN settings. You need to change the
TCP/IP connection settings. For example, on a PC running Windows, go to the
Local Area Connection Properties > Internet Protocol > TCP/IP Properties
window. Choose
Use the following DNS server address
, and then enter the LAN
IP address of the router as the Preferred DNS Server. For more information, refer to
the documentation for the client that you are configuring.
Add or update entries as needed. Remember that the settings are not saved until
you click the Save button.
