DynDNS
##################

You can find the DynDNS Settings at **General → DynDNS**.

DynDNS can be used to have a DNS name for a dynamic IP.
We currently support the following **Service Types**:

.. note::
    * DynDNS
    * Gandi
    * dnsHome
    * Strato
    * Custom Script

**IP Type** choose either IPv4 or IPv6

**Connection** can be an Interface and the according Interface IP, a Routing Table or Periodic Check.
The Periodic Check runs every 2 minutes and checks if the IP address changed and the DynDNS will be executed.
On Routing Table the current default gateway will be used as the IP.
If the routing table has multiple gateways with the same ip, the active one that was created first is used.

**Hostname** including the domain (test.voleatech.com) that the IP should be assigned to.

**Username** if applicable to authenticate at the Service.

**Password** if applicable to authenticate at the Service.

**Custom Script** if you choose custom script as Service Type.
This will be run with minimum user rights and should not access any system ressources.
There are environment variables that can be used in the script from the GUI values:

.. note::
    * USERNAME
    * PASSWORD
    * HOSTNAME
    * IPADDRESS
    * IP_TYPE
