Dynamic DNS: Name Instead of IP Address

Address for Accessing the FRITZ!Box
If you have enabled the ports for forwarding in the FRITZ!Box,
other users can access your computer at the IP address as-
signed to your FRITZ!Box by the Internet Service Provider. This
is a public IP address.
Here is how to determine the public IP address of the
FRITZ!Box:
1. Open the FRITZ!Box user interface (see page 25).
2. Enable the expert settings in the “System / Expert
Mode” menu.
3. Open any Internet page in order to establish an Internet
connection.
4. The FRITZ!Box’s public IP address is displayed on the
“Overview” page in the “Connections” area.
8.3 Dynamic DNS: Name Instead of IP Address
Dynamic DNS is an Internet service that makes it possible for
the FRITZ!Box to remain accessible from the Internet at all
times under a fixed name, even though the public IP address
changes.
You must register with a dynamic DNS provider to use this
service. When you register, you agree on the fixed name (do-
main name) at which your FRITZ!Box should be accessible
from the Internet. You also define a user name and password.
Every time the IP address changes, the FRITZ!Box transmits
the new IP address to the dynamic DNS provider in the form of
an update request. Then the domain name is assigned to the
current IP address by the dynamic DNS provider.
Every time the Internet connection is interrupted the Internet
Service Provider re-assigns the IP address. The IP address
may change in the process. Therefore it is a good idea to use
dynamic DNS so that the IP address can always be reached
under the same name. For more information, see the section
Dynamic DNS: Name Instead of IP Address on page 35.
