Dynv6-DDNS is a dynamic DNS tool.
It uses the Dynv6 API to automatically updates the records of your domain.
This application is intended to run as a system service on system startup.
By default, the application tries to fetch the current IP address every hour.
If it detects that the IP has changed, the domain gets updated.
