Detecting when a network is connected

[Guest]

I know how to detect when a network cable has been plugged in or out, but how
can I detect when an IP address has been received through DHCP? I e how to
detect when the small "connecting to network" icon in the notification area
beside the clock turns to a "connected to network" icon?
