Hi Niels,

This is currently not possible, but it sounds like a great idea. 

It may be good to know that the netmaskgroup currently just tries all
netmasks to see if one fits, you could easily emulate this in Lua itself,
and it would not be slower. And then you would know which address matched.

Could you open a ticket requesting this feature on github?  Please put a
note in there we find it a fine idea.
