# PowerDNS Proxy

PowerDNS Proxy is a Python script that acts as a proxy between your PowerDNS server and external DNS providers, such as Hetzner and OVH. It allows you to automatically synchronize DNS records between your PowerDNS server and the supported external DNS providers.
Mainly aimed at proxying RDNS/PTR records.

## Features

- Synchronize DNS records between PowerDNS and supported external DNS providers.
- Automatically track changes in PowerDNS zones and update corresponding records in external DNS providers.
- Supports multiple backend providers, including Hetzner and OVH.

## Installation

1. Install the required Python dependencies:
```bash
pip3 install -r requirements.txt
```

3. Configure the PowerDNS Proxy by editing the `config.ini` file:


Replace values `x` with the appropriate values for your PowerDNS server and backend providers. You can also change the synchronization frequency (in seconds) by modifying the `frequency` parameter. Backend servers will only get called on zone change.

4. Define the zones and their corresponding backend providers in the `zones.ini` file:
```ini
[1.2.3.4.in-addr.arpa.]
backend = hetzner

[5.6.7.8.in-addr.arpa.]
backend = ovh

[2.4.6.8.in-addr.arpa.]
backend = hetzner
```

Each section in the `zones.ini` file corresponds to a zone in your PowerDNS server. The `backend` parameter specifies the backend provider to use for that zone (currently supporting `hetzner` and `ovh`).

## Usage

Run the PowerDNS Proxy script using the following command:
```bash
python3 main.py
```

## Supported Backends

#### OVH

- Supports creating, updating, and deleting DNS records using the OVH API.

#### Credentials
To get credentials, go to this link here: https://github.com/ovh/php-ovh#supported-endpoints, pick the right endpoint and go to the right **/createApp/** application credentials page.
The application needs to have the following rights:
