This command will return the interface with the default gateway in a
parsable way:

C:\Users\benoitc> wmic nicconfig get SettingId,DefaultIPGateway /format:csv


 now I could use the `where INDEX=X` condition if I am sure that
`inet:getifaddrs/0` always return in the same order. Not sure yet how to
filter using the SettingId...
