The Dynu iOS App allows users to manage their dynamic DNS service as well as other services of the Dynu account with an easy-to-use mobile application. The IP Update Client utility in the app detects any changes to your IP Address and reports it to Dynu DNS servers so that your domain name keeps mapped to the dynamic IP address detected by the App. This application supports IPv4 and IPv6 updates as well as group and is an essential part of the dynamic DNS service.
