Official Description

IP Monitor v2.4 is the ultimate dynamic DNS update client for Mac.

IP Monitor works with more than 35 popular DDNS service providers, and can monitor public IPv4 and IPv6 address changes across multiple active network interfaces. Since IP Monitor can distinguish between separate networks, it works without interruption should your server ever be on the move, either physically or virtually. 

From the straightforward on/off switch to the color-coded tables listing active networks and their preferences, IP Monitor’s user interface was built for intuitive usage. The user interface’s dialogue dynamically adapts to each service provider’s features and terminology, while info buttons provide guidance at each step. And, if something doesn’t go as expected, simply consult the service provider-specific diagnostic report offered with each query and update attempt. Meanwhile, sensitive information, like passwords, are saved only in your system’s keychain.

Upon each login, IP Monitor will start running in the background, only alerting you, should you choose, to IP address changes, DDNS record updates, and changes in active network interfaces—out of sight, but always keeping you up to date.
