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.
! When you use the built-in DHCP server, the network parameters (including DNS servers)
are distributed to clients automatically.
