The networkhotplug object can be used to generate events when

a 

a network interface becomes available or unavailable.

 A

 A networkhotplugevent will be generated, indicating the interface and whether it was attached or detached.

Note

Reconfiguring a network interface may cause it to detach and attach again.  A DHCP address renewal may cause an event, even if the IP address hasn't changed.
