A php-script to update name server records. At the moment only the registrar INWX is supported.
Host this script and its dependencies on a php enabled webserver. All dependencies are included in the folder 'inc'.
Call this script with your router/modem when it gets a new IP assigned.

key : Not used yet. user : Username for the registrar account. password : Password for the registrar account. domain1 : Data for the first domain. Up to 50 domains are supported. domain2 : Data for the second domain.
user : Username of the registrar account.
password : Password of the registrar account.
webserver_ip : IP of the webserver on which the php script is hosted.
webserver_port : Port of the webserver on which the php script is hosted.
account_key : Not used yet.
domain : Domain name.
ipv4 : New IPv4 address of the domain. Set to 0 if this domain has no IPv4.
If left empty, then the IPv4 from the previous domain will be used.
Format: 172.217.5.110
ipv6 : New IPv6 address of the domain. Set to 0 if this domain has no IPv6.
If left empty, then the IPv6 from the previous domain will be used.
Format: 2607:f8b0:4005:808::200e
ipv6prefix : A prefix for the new IPv6 address. The new IPv6 address for the domain
will be build from the given IPv6 and this prefix if the prefix was specified.
Set to 0 if no prefix is needed.
If left empty, then the prefix from the previous domain will be used.
Format: 2611:a460:a460:808::200e/64
determineip6 : Set to true if the new IPv6 should be determined by the server itself
with the "ip" command. Else set to false.
If left empty, then the boolean from the previous domain will be used.
The basic auth method is used to transfer the user name and password. Be aware that the username and the password will not be encrypted if no https connection is used.
The server needs some time to update its own IPv6 before it is able to determine its IPv6. Therefor the script sleeps a few seconds before trying to determine the IPv6. If the script times out, you want to increase the time the script is allowed to run. In nginx this can be done with the following parameter: fastcgi_read_timeout 140s;
The script was tested with a Fritzbox 3390 using the dyndns function of the Fritzbox.
- https does not work
- username and password can be saved in the input box.
- one domain name can be saved in the input box. This domain name will be used to check if the ip of the domain points to the Fritzbox.
In the URL following placeholders can be used and will be replaced by the Fritzbox:
<username> : User name saved in the input box.
<passwd> : Password saved in the input box.
<domain> : Will be replaced by domain saved in the input box.
<ipaddr> : Will be replaced by the current global IPv4 of the Fritzbox.
<ip6addr> : Will be replaced by the current global IPv6 of the Fritzbox.
<ip6lanprefix> : Will be replaced by the current global IPv6 prefix
of the Fritzbox provided by the internet provider.
This does not work with the Fritzbox 3390,
but newer models support this placeholder.
