 This is the correct subnet matching that of the host.

 When the host system boots, LXC decides the order and the delay between each startup.
-In this case:
-  * The first line actually does the autostart.
-  * The second line is optional and will delay the start of this container to give the current container time to begin initialization and reduce overloading the host system.
