DuckDNS

Duckdns is a free service which will point a DNS (sub domains of duckdns.org) to an IP of your choice. The service is completely free, and doesn't require reactivation or forum posts to maintain its existence.

Application Setup

Go to the duckdns website, register your subdomain(s) and retrieve your token
Create a container with your subdomain(s) and token. If you own user.duckdns.org, you put SUBDOMAINS=user you would NOT put a sub subdomain like overseerr from overseerr.user.ducksdns.org
It will update your IP with the DuckDNS service every 5 minutes (with a random jitter)

Notice regarding automatic detection

Using the UPDATE_IP variable whatever its value (ipv4, ipv6 or both) uses external Cloudflare whoami service to detect public IP addresses. Be aware that using this variable will query a third-party service other than DuckDNS.

Omitting the UPDATE_IP variable uses DuckDNS for detection and only supports IPv4.
