With the DuckDNS integration you can keep your DuckDNS record up to date. DuckDNS is a free dynamic DNS service that allows you to point a subdomain under
duckdns.org at your computer.
To use the integration in your installation, add the following to your
# Example configuration.yaml entry duckdns: domain: YOUR_SUBDOMAIN access_token: YOUR_ACCESS_TOKEN
If you are running the Hass.io DuckDNS add-on this integration is not required. The add-on will keep your IP updated with DuckDNS.
