Can Always Be Reached, Even When the IP Address Changes
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
MyFRITZ! or dynamic DNS so that the IP address can always
be reached under the same name. For more information
about MyFRITZ!, see the chapter
. For more information
about dynamic DNS, see the section

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.
Dynamic DNS can be used as an alternative to MyFRITZ!. Both
services can be used in parallel.
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.
