A configuration is a collection of settings representing a specific network implementation.
A configuration includes DNS zones, IP address space, servers, and all of the settings used to control and manage the network. In the Address Manager object structure, the configuration is the parent IPAM object, encompassing all other objects in the network. Settings such as DNS and DHCP options and access rights made at the configuration level are inherited by all objects within the configuration.
You can create multiple configurations to maintain different networks and to perform testing in an isolated environment without interfering with production servers.
The Configurations page (Global → Configurations) lists all available Address Manager configurations. You can use this page to add new configurations and quickly jump to any configuration in Address Manager.
You can switch configurations from the Configurations page or by selecting a
configuration from the configuration selector at the top-right of the Address Manager user interface. 
You can only view configurations to which you have been granted the appropriate access rights.
