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.
