Documentation

Overview

Package agent provides a long-running MyDynDNS agent for keeping DNS records up-to-date with a Client-reported apparent IP address. An Agent process is configured to check the apparent IP address at regular intervals. At each interval, the latest-retrieved IP address is compared to the previously-retrieved IP address. When the compared values differ, the Agent attempts to update DNS records accordingly.
