Configuring Dynamic DNS

  1 minute read.

Dynamic Domain Name Service (DDNS) is useful when TrueNAS is connected to an ISP that periodically changes the IP address of the system. With dynamic DNS, the system can automatically associate its current IP address with a domain name and continue to provide access to TrueNAS even if the system IP address changes.

DDNS requires registration with a DDNS service such as DynDNS before configuring TrueNAS. Have the DDNS service settings available or open in another browser tab when configuring TrueNAS. Log in to the TrueNAS web interface and go to Services > Dynamic DNS.


The required values for these fields are provided by your DDNS solution. Start the DDNS service after choosing your Provider options and saving the settings.

For more information on the configuration settings see Dynamic DNS screen.
