# netcup DNS

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

## Configuration

For each netcup customer, create a `.ini` configuration file. Here is an example:

```ini
[credentials]
customer = 123456
api_key = abcdefghijklmnopqrstuvwxyz
api_password = abcdefghijklmnopqrstuvwxyz

[example.com]
hostname = @
type = A

[foo.bar]
hostname = @
type = A
```

## TODOs

Alternative external IP detection:

```python
def external_ip_upnp():
    """
    https://stackoverflow.com/a/41385033

    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()))
```
