To update the IP address of your hostname,
just copy and paste the following line into a new tab of your
browser, replace YOURUSERNAME and YOURTOKEN
with your username and the token, corresponding to the defined host.
(the token can be found at "My Account")

https://int-ern.de/dev/intdyn/refresh.php?user=YOURUSERNAME&token=YOURTOKEN&usereq=1


Linux users can just execute wget and create a cron job, e.g. called every 24h
Just change the variables as described above, so they match to your account and host.


wget -q -O /dev/null "https://int-ern.de/dev/intdyn/refresh.php?user=YOURUSERNAME&token=YOURTOKEN&usereq=1"


If you like to assign a static IP for your host,
just use "ipv4=x.x.x.x" instead of "usereq=1"

You have the possibility to set up our Int-Dyn Service for a variety of router hardware.
For technical reasons, setting up Int-Dyn on those requires additional data to work properly.
We do not guarantee that this works for all hardware.
Set the dynamic DNS service on your router to "custom"
and enter int-dyn.de into the domain field. Please use "router" as username and "router" as password.
By using our tokens as authentication method these additional credentials are
not important and therefore are identical for all users.

For these additional credentials to work, you have to alter the link,
provided in the My Hosts menu from int-dyn.de.

Instead of
https://int-ern.de/dev/intdyn/refresh.php?user=YOURUSERNAME&token=YOURTOKEN&usereq=1

you have to add "fb/" right after "intdyn/":

https://int-ern.de/dev/intdyn/fb/refresh.php?user=YOURUSERNAME&token=YOURTOKEN&usereq=1

Attention! For Fritz! Products with firmware greater than version 5.50 you have to remove "/fb" from the following URL:

If you run into trouble refreshing your IP, please make sure your device runs with the latest firmware.
For the Fritz! products we have sucessfully tested our int-dyn service with Fritz!OS 5.22.
Possibly it might help to use "http://" instead of the secure "https://".
Please be advised that others might be able to read out the data, transmitted over an unsecure protocol.
Services where user logins are used, like int-dyn and any other service you find on the internet,
a secure protocol (like ssl) is always recommended.

Contrary to similar services you don't need your account's password for refreshing an ip address.
The authentication works with an username and a token which is unique for each host.
With these concept you can ban a single host and other persons who possibly have access to a machine
cannot use your credentials for logging in to the web interface or change other hosts' configuration.

A mail exchanger record (MX record) is a type of resource record in the Domain Name System
that specifies a mail server responsible for accepting email messages on behalf of a recipients domain,
and a preference value used to prioritize mail delivery if multiple mail servers are available.
The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol..
