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.
