Please add unit tests and add new config into the default conf file with description to make the feature discoverable.

I think this might be useful for hosts with multiple network interfaces

@dlg99 I do not think there need a new config, we just use the existed config advertisedAddress.

If we use InetAddress.getLocalHost() instead of use config advertisedAddress, there is problem.

I add more log, take a look please. #2784
