no it isn't that good, makes also issues when editing settings on another node,
as that one then shows the local CIDR again, and marks the UI form as invalid..
E.g., edit the "migration network" when connected to two different nodes.

I have some work calculating the network from CIDR in javascript, but it's pretty
ugly - at least for IPv6. So I thought of passing back the network the IP is in 
from our API network call, or add a new API get call just for available networks,
which would make this way easier to integrate correctly in webinterface.

What do you think?
