See the Custom Dynamic DNS article for instructions on how to configure a custom Dynamic DNS service.

CLI: Access the EdgeRouter Command Line Interface.

1. Enter configuration mode.

configure

2. Add the Dynamic DNS service and the login credentials.

set service dns dynamic interface eth0 service <dyndnsservice> host-name <host>
set service dns dynamic interface eth0 service <dyndnsservice> login <username>
set service dns dynamic interface eth0 service <dyndnsservice> password <password>

3. Configure the location of the Dynamic DNS server.

set service dns dynamic interface eth0 service <dyndnsservice> server <server>

NOTE: This step is required when using afraid.org.

4. Commit the changes and save the configuration.

You can verify the status and force an update of the Dynamic DNS service using the commands below:

show dns dynamic status
update dns dynamic interface <interface-name>

By default, EdgeOS will only update Dynamic DNS when the IP address actually changes.
