Listening on a specific interface

[Kamal Kumar Panta]

I have a requirement where my application should listen only on the management interface. And the management interface ip could be changed from my application.

How to specify so that it always listens only on the management interface though the ip could change.

If you can trigger a request when IP changes you can listen to that request and make the necessary changes.

Not sure where the requirement comes from, but I feel this is inherently a bad / fragile design to have the application itself care about it. 

Much better to make that a configuration concern, and let the sysadmins ensure it's set correctly.  I generally use the Convict module for this sort of thing, but basically you have the application pull the IP it should listen on via the convict config file or an environment variable or whatever.
