Configure Dynamic DNS
Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano
You can use Dynamic Domain Name Server (DDNS) to ensure that whenever the DHCP server changes the Pearl device's IP address, the Pearl device informs the DDNS to update its domain name records. That way, you can keep using the Pearl device's FQDN without worry. The DDNS feature is useful if your DHCP server doesn't support Option 81. Custom DDNS servers, dyndns.org, and noip.com are supported.
Table — DDNS Fields
| Label | Description/Options |
|---|---|
| Provider | Choose if the DDNS provider is dyndns.com, noip.com, or a custom DDNS server of your choice. |
| DDNS server name | If you are using a custom DDNS provider, you must enter the DDNS server name. If dyndns.com or noip.com are used, you can leave this field blank. |
| DDNS server path | If you are using a custom DDNS provider, you must enter the DDNS server path. If dyndns.com or noip.com are used, you can leave this field blank. |
| Use SSL | Choose if you will use Secure Socket Layer (SSL) encryption for communications with the DDNS server. This is enabled by default. |
| Update period | Enter how often the device updates the DDNS server with its new IP address when the DHCP server changes it. Enter the update period in seconds from 30 to 864000 seconds (i.e. up to a maximum period of 10 days). The default is 600 seconds. |
| Username | Enter your user name for the DDNS provider. |
| Password | Enter your password for the DDNS provider. |
| Hostname | Enter the hostname to use for this device in the DDNS server records. The device's serial number is the default hostname. |
| External IP detection server name | If your DDNS provider uses an external IP detection server, you must provide that server's name. |
| External IP detection server path | If your DDNS provider uses an external IP detection server, you must provide that server's path. |
| Use SSL for external IP detection | Choose if you will use SSL encryption for communications with the external IP detection. This is enabled by default. |
The status of the connection to the DDNS server, the last external IP address of the device that was reported to the DDNS server, and the time when the IP address was reported is shown.
Configure DDNS using the Admin panel
Log in to the Admin panel as admin
From the Configuration menu, select Network and then select the Dynamic DNS tab. The Dynamic DNS page opens.
Under Dynamic DNS, check Enabled and in the Provider field, choose either Custom, dyndns.com, or noip.com in the drop-down menu.
If you selected Custom as the provider, enter the DDNS server name and DDNS server path. If dyndns.com or noip.com were selected as the provider, you can leave those fields blank.
Enter the Username and Password for your DDNS server.
In the Hostname field, enter the hostname of your Pearl device, for example: mypearl. The default hostname is the serial number of the device.
If your DDNS provider uses an external IP detection server, enter the External IP detection server name and External IP detection server path.
Check Use SSL for external IP detection if you want to use that feature with an external IP detection server.
(Optional) Change the Update period in seconds.
Click Save.
Reboot your Pearl device when prompted.
After the system has finished rebooting, log back in to the Admin panel as admin and verify that all changes were applied.
