The project is implemented in modern Perl and is distributed on CPAN
as `App::sdseasydyn`.

## Features

- Simple CLI interface (`sdseasydyn update`)
- Clear configuration precedence: CLI > environment > config file > defaults
- Secure handling of credentials (tokens are never logged)
- Public IPv4 discovery with configurable endpoint
- Local state file to avoid redundant updates
- Bounded retry logic using `Retry::Policy`
- Suitable for unattended / scheduled execution

# Notes for EasyDNS users / EasyDNS team

This project provides a small command-line Dynamic DNS updater for EasyDNS.

## Endpoint used

This tool uses the classic EasyDNS Dynamic DNS update endpoint:

- `https://api.cp.easydns.com/dyn/generic.php?hostname=...&myip=...`

Authentication is performed via HTTP Basic Auth using your EasyDNS credentials/token.

## Behavior and safety

- The updater stores the last-known public IP in a state file and **skips** the EasyDNS update call when the IP is unchanged.
- Secrets are not printed in normal or verbose output.
- Retries transient network failures using `Retry::Policy` (exponential backoff + jitter).
