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

---

## Quick start

sdseasydyn update --host example.easydns.net

- Please **do not** open a public GitHub issue with sensitive details.
- Email: **sergio@serso.com**
- Include: a short description, reproduction steps (if possible), and impact.

I will respond as soon as practical and coordinate a fix/release if needed.

## Security Notes

- This tool is designed to avoid logging secrets (e.g., tokens).
- Recommended practice is to store credentials in environment variables (e.g., `EASYDNS_TOKEN`) and reference them from config.

# 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).

## Quick start

- See `README.md` and `docs/HOWTO.md`
