OpenDNS Updater

OpenDNS Updater is a client that keeps an OpenDNS account synchronized with the current public IP address of a machine. It periodically queries the external IP and, when a change is detected, sends an update to the OpenDNS service so that the configured DNS settings continue to point to the correct host. The tool runs as a background process on macOS, automatically handling the communication with OpenDNS without user intervention.

The software is aimed at users who rely on OpenDNS for content filtering, security, or custom DNS routing and who have an internet connection that does not provide a static IP address. By maintaining an up‑to‑date IP record, it ensures that the OpenDNS policies remain effective even when the network address changes, such as on residential broadband or mobile connections.

OpenDNS Updater is distributed as a stable, macOS‑only package. It is lightweight, requires no manual configuration after initial setup, and operates continuously to detect and report IP changes, reducing the need for manual DNS updates.
