If you want to keep it lightweight instead of bringing in the heartbeat
framework, you can script something up based on the ping response itself.

ping -c1 ip.address.of.A || do_ip_change_etc

You'll have to run it in a loop. And think of the sleep time between pings, and
number of ping fails before you switch.
