xProDDNS checks for IP address changes, sends email and text message alerts, and updates No-IP, Dyn, OpenDNS and DNS-O-Matic hosts using very efficient realtime background tasks and remotely accessible mobile and full web user interfaces. xProDDNS runs natively on Windows, OS X and Linux. It is fast and efficient. Workstations and headless servers are equally easy to manage thanks to local and remote access via mobile and full web user interfaces powered by a built-in web server. Security is paramount so all data is encrypted and the login passphrase is stored as a hash derived from an obfuscated salt.
