Ntp should listen on configured addresses only. By default, the ntp server does not listen to any interface. The question here is for extending the cli and bind ntp to a specific ip (we should add this).

The Hostnames '*.Pool.ntp.org' Point To Different # Servers Each Time, Using A Round Robin System.

Confused and eventually stopped serving time. That parameter specifies a class of addresses, or a specific interface name, or an address. Distributes keys to keys file.
