2 Public IP address required for access

You can only access the FRITZ!Box over the internet if the FRITZ!Box obtains a public IPv4 address or an IPv6 address from your internet service provider when it connects to the internet.

Access via IPv4

For IPv4 internet access, the FRITZ!Box must obtain a public IPv4 address from the internet service provider. Access over IPv4 is not possible if the FRITZ!Box obtains a private IPv4 address.

You can find out whether the FRITZ!Box obtained a public or private IPv4 address by following the steps in our guide Identifying the address range of the IPv4 address for the internet connection.

Access via IPv6

For IPv6 internet access, both the FRITZ!Box and the device that is to access the FRITZ!Box must be connected to the internet over IPv6. If only the FRITZ!Box obtains an IPv6 address but the other device is not connected to the internet via IPv6, IPv6 internet access is not possible.

You can call up the menu "Internet > Online Monitor" in the FRITZ!Box user interface to determine whether the FRITZ!Box is connected to the internet via IPv6.

You can test whether the device that is to access the FRITZ!Box is connected to the internet over IPv6 by calling up www.test-ipv6.com or www.ipv6-test.com on the device.
