DuckDNS - Free Dynamic DNS Service

DuckDNS is a free dynamic DNS (DDNS) service that allows users to map a subdomain underduckdns.orgto their dynamically changing IP address. This is particularly useful for home servers, IoT devices, and self-hosted services where the ISP assigns a new IP address periodically. The service is entirely free with no paid tiers—operational costs are covered through optional donations via Patreon and Bitcoin.

Key Features

Free dynamic DNS with subdomains likeyourname.duckdns.org
Simple HTTP/HTTPS API for updating IP addresses (works with scripts, routers, and IoT devices)
Automatic IP detection when no IP is specified in the update request
Custom domain support via CNAME records pointing to your DuckDNS subdomain
Multiple authentication options: Google, GitHub, Twitter (Reddit login discontinued due to legal request)
Minimal data collection: only stores email, IP, token, domains, and target IPs

Technical Infrastructure

Hosted entirely on AWS (Amazon Web Services)
Primary server: 15.223.156.67 (AWS Canada - ca-central-1)
9 nameservers (ns1-ns9.duckdns.org), all on AWS Canada infrastructure
Mail: Handled by Amazon SES (inbound-smtp.us-west-2.amazonaws.com)
DNSSEC: Not signed
IPv6: Detection not currently supported due to AWS VPC limitations

History & Community

DuckDNS was created by a small team who wanted a simple, reliable DDNS service for their own use. The project operates at minimal cost by leveraging AWS infrastructure efficiently. It has gained recognition in the self-hosting community and was recommended by Gnu Tomorrow as a quality free DDNS option. The service maintains an active community through Google Groups for support and discussion.
