Network Settings in the FRITZ!Box
Unique Local Addresses
Communication within the local network takes place via the
Unique Local Addresses (ULA). If no IPv6 Internet connection
is established, the network devices do not have a ULA and
communication between them is restricted. For this case you
can set the FRITZ!Box such that the network devices receive
the ULA from the FRITZ!Box.
DHCPv6 Servers in the Home Network
The FRITZ!Box is equipped with its own DHCPv6 server. The
DHCPv6 server of the FRITZ!Box is switched on by default.
The DHCPv6 server assigns the network devices their IPv6
settings. These settings are used instead of the data in the
router advertisement messages. The DNS server, IPv6 prefix-
es or IPv6 addresses can all be assigned by DHCPv6. Define
which IPv6 settings should be assigned by the DHCPv6 serv-
er.
