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.
