DIR-879 Quick Installation Guide
4. IPv4 address assignment. By default, the built-in DHCP server of
the router assigns IPv4 addresses to the devices of the LAN. If you want
to manually assign IPv4 addresses, disable the DHCP server (click the
IPv4 tab and select the Disable value from the Mode drop-down list in
the DHCP section).
5. IPv6   address   assignment.   By   default,   the   devices   of   the   LAN
automatically assign IPv6 addresses to themselves (the Stateless value
is selected from the  Autoconfiguration mode  drop-down list in the
DHCP section on the IPv6 tab). If the devices of the LAN do not support
IPv6 address autoconfiguration, enable the built-in DHCPv6 server of the
router (select the Statefull value from the Autoconfiguration mode
drop-down list). If you want to manually assign IPv6 addresses to devices
of the LAN, select the Disable value from the Mode drop-down list.
6. After specifying the needed parameters on the  Connections Setup /
LAN page, click the APPLY button.
