    I'm wondering whether it's better to have `null` as default and simply let 
InetAddress pick the address. I don't know if it makes a difference at the end.

> Currently the web interface automatically binds to all interfaces on 0.0.0.0. 
> IMHO there are some use cases to only bind to a specific ipadress, (e.g. 
> access through an authenticated proxy, not binding on the management or 
> backup interface)
