# netcup DNS

Update DNS A/AAAA records with your current external IP address using the netcup DNS API.

## Installation

On Arch Linux:

```shell
make
```

With `pip`:

```shell
make install-pip
```

## Configuration

For each netcup customer, create a `.json` configuration file inside `/etc/netcup-dpns`.

There is an [example configuration](cfg/example.json).

## TODOs

Alternative external IP detection:

```python
def external_ip_upnp():
    """

    Didn't work for me. Even after double checking fritz.box settings:

    fritz.box > Heimnetz > Netzwerk > Statusinformationen über UPnP übertragen
    """
    import miniupnpc
    u = miniupnpc.UPnP()
    u.discoverdelay = 1000
    u.discover()
    u.selectigd()
    print('external ip address: {}'.format(u.externalipaddress()))
```
