On the Advanced / DNS page, you can add DNS servers to the system.
Figure 142. The Advanced / DNS page.
DNS servers are used to determine the IP address from the name of a server in Intranets or the
Internet (as a rule, they are specified by an ISP or assigned by a network administrator).
You can specify the addresses of DNS servers manually on this page or configure the router to
obtain DNS servers addresses automatically from your ISP upon installing a connection. Also here
you can specify addresses of reserve DNS servers which the router can use if the addresses
specified manually or obtained automatically are unavailable.
