About
Duck DNS is a dynamic DNS service hosted on AWS. It provides public DNS subdomains that users update from a home computer or router by sending periodic HTTPS posts with the latest external IP address.
The service is used to map a changing home IP address to a stable hostname for remote access to services such as web servers and SSH. The page describes client updates every 5 minutes and support for router port forwarding, but it does not state any explicit free usage limits on the landing or pricing content provided.

Free Tier Value
This free tier is a small but real ongoing service: it includes a subdomain, public DNS access, and periodic HTTPS updates, so it has clear practical value even though there is no published paid plan to anchor against. With no credit card requirement shown and no time limit mentioned, a conservative buyer-equivalent estimate is about $2/month for the basic DDNS capability.
What's included in the free tier
- Free dynamic DNS hosted on AWS.
- Public DNS server access for a subdomain.
- Periodic record updates via HTTPS posts from a client computer.
See Duck DNS pricing for current limits.
