Configure Dynamic DNS

You can use Dynamic Domain Name Server (DDNS) to ensure that whenever the DHCP server changes Pearl-2's IP address, Pearl-2 informs the DDNS to update it's domain name records. That way, you can keep using Pearl-2'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.

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 Pearl-2 updates the DDNS server with Pearl-2's 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.

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 Pearl-2 that was reported to the DDNS server, and the time when the IP address was reported is shown.
