Reserved IP Addresses
The following IPv4 addresses cannot be assigned because
they are reserved for certain purposes:
The entire IP network 192.168.180.0 in the FRITZ!Box is re-
served for internal purposes.
IPv4 addresses from this network may
not
be assigned to the
FRITZ!Box.
Changing the IPv4 Address
In most home networks it is not necessary to change the IPv4
settings.
Yet there are situations in which it makes sense to adjust the
IPv4 settings of the FRITZ!Box. For instance, in the following
case:
•
You have an existing local IPv4 network, one subnet with
several computers.
•
Fixed IPv4 addresses are registered in the network set-
tings of the computer, and you do not want to or are not
permitted to change these addresses.
•
You want to connect the FRITZ!Box to the local IPv4 net-
work in order to make the FRITZ!Box features available to
all of the computers in the IPv4 network.
IPv4 Address in Case of Emergency
The FRITZ!Box has a fixed IPv4 address that cannot be
changed. The FRITZ!Box always can be reached at this IPv4
address.
