Warn

This scripts save the configurations in plain text, including the secrets needed to update domains. Beware warned that is not a secure way to store credentials, use it at your own risk.

This tool is not designed to be used on any production environment.

Some notes

I've developed this utility for myself but I've found that could be interesting to share for people interested developing minimalistic bash scripts or maintaining dynamic dns hosts.

You can find an official no-ip client which can be better than this simple script, you can check it out here. To setup no-ip on this tool, the credentials must be the email and password of your account.

On Google Domains, Dynamic DNS hosts are supported. You need to get the credentials (username/password) of the host you want to update.

For GoDaddy, look documentation to generate the needed api keys: https://developer.godaddy.com/getstarted and https://developer.godaddy.com/keys

For ChangeIP, to setup this tool, the credentials must be the email and password of your account.
