I am trying to replace public ip with private ip in /etc/hosts for bulk of hosts .

Current setup

PUBLIC\_IP hostname shot\_hostname

Needed :

PRIVATE \_IP hostname short\_hostname

How I can do it using ansible? I wonder if it can be done using gathered facts by ansible?  
I would think of , getting the public ip and register as variable and same time get the private ip .  
Now, replacing it using replace or inline module. Any best approach ?
