No-IP DUC
No-IP DUC (Dynamic Update Client) is the official dynamic DNS client from No-IP, a service that maintains a domain name pointing to your home or office internet connection even when your public IP address changes. It runs in the background and automatically updates your hostname whenever your ISP reassigns your IP. Users typically rely on it to maintain stable remote access to home servers, network-attached storage, security cameras, or other services running on a residential or small-business connection without a static IP.
AI Recommendation
1 suggestionNo-IP DUC has been discontinued by its developer and is no longer supported. The search results indicate the app is end-of-life and does not have an active native Apple Silicon build — it was last updated years ago. Since it is Intel-only and Apple is removing Rosetta 2 in macOS 28 (September 2028), this app will stop launching entirely on that release. You should plan to migrate away from it before then. If you still need dynamic DNS support, consider these alternatives: First, check whether No-IP offers a newer command-line client or script-based tool on their website that you could run via cron or a third-party scheduler. Second, many modern WiFi routers and network-attached storage devices now have built-in dynamic DNS support — you may be able to configure your DNS update directly on your hardware without needing a separate Mac application. Third, if you are comfortable with the terminal, open-source tools like inadyn or ddclient can be installed via Homebrew and run as a LaunchAgent to keep your DNS record current. If you need a polished Mac app alternative with native Apple Silicon support, some third-party dynamic DNS clients exist on the App Store, though you should verify they support your DNS provider (No-IP) specifically before switching.
