## TODOs
|
|
|
|
API backend:
|
|
|
|
- Currently: nc-dnsapi
|
|
- Alternatives:
|
|
- https://github.com/johndoe31415/dnssync_nc
|
|
|
|
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()))
|
|
```
