The last number is actually the interface index, but the path itself 
isn't something you need to worry about deriving yourself. Instead you 
can use the org.freedesktop.DBus.ObjectManager interface and 
GetManagedObjects() method. This returns all the object paths and 
interfaces for IWD.

If your working with Python you can check out IWD's test framework as a 
guide:
