The Hosts and Groups application simplifies management of objects on a network which can be identified by IP address, Domain, MAC Address or service. These objects can also be members of groups based on IP, Domain, MAC and Service. Objects are then linked with different application configurations and these configurations are automatically updated with any changes to objects without the need for any further configuration. This feature greatly simplifies the management of rules, policies and schedules across an environment.

Note: It is suggested to set up Groups ahead of defining Hosts to make the process simpler if you plan to utilise your own custom Groups.
