Comment 3 for bug 1350777

@Yuki Nishiwaki, I'm sorry.
But I think temporary move ip address is very dangerous. Since this move will lose efficacy once user reboot os or restart network. Which means once user reboot os or restart network, the ip address can not be accessed any more. However, to a linux server, losing network connection almost means losing its control.
And actually, we did some more about ip movement by modify linux network configuration files. And plan to write a blue print to track those complexity steps. Do you mind to implement it together ?
