As the function get_server_private_ip says, it will look for an IP on the 'private' network for a server.
Why restrict the key_name to be 'private'? As I know the key_name here should be the network name. Why should I always name the network to be 'private' when using it to create a server?

This is an example, the server details got by shade is

To my knowledge, it should get the ip '192.168.120.9' as this server's private ip. However, the only key of the 'addresses' is 'vping_ssh-net_f40e24f4-882f-4e53-9547-632f255955c4' which is the network name rather than 'private'. So it will return a empty dict.
I don't understand why it need to restrict the key to be 'private' which is just the name of the network.
