Setup Duck DNS in Home Assistant for DDNS Only

Home Assistant Logo

Setup Duck DNS in HomeAssistant for DDNS Only.
Without setting up Lets Encrypt, Port forwarding etc.
This mini guide is to get the Dynamic DNS functionality only.

Create Duck DNS Account

Go over to https://www.duckdns.org/ and signup for an account or login if you already have one.
Annoyingly the only way to sign is is via Persona, Twitter, Github, Reddit or Google.
They do not offer a DuckDNS account and it is not made obvious.
It is recommended to create a new account just for this service alone and not use it for anything else.

Create a Duck DNS Sub Domain

Over at duckdns.org create a new subdomain xxx.duckdns.org.

You will be provided with a token. This will be needed by the Duck DNS App in Home Assistant.
