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 like
yourname.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.
