Managing Zones

For an overview of zones and how they fit into the network model, see Zones.

Shrinking or splitting zones

The Zone Editor cannot be used to shrink a zone if there are assets that fall outside the range of the new zone. For example, if you have a zone with an address range of 192.0.2.1 to 192.0.2.27 and an asset in that zone with an IP address of 192.0.2.15, you cannot change the upper end of the zone range to 192.0.2.10 but you can change it to 192.0.2.20.
For shrinking or splitting zones that might encounter such issues, we suggest using a package export and import operation. You can export the asset resources and then import them back in. Package import and install automatically assigns assets to appropriate zones similar to the auto-zoning used by the Network Model Wizard. See Managing Packages, Populating the Network Model Using the Wizard, and Auto-Zoning Imported Assets.

Keeping separate zones for mixed-family IP addresses

If your network has both IPv4 and IPv6 addresses, have separate zones for IPv4 and IPv6 addresses. When an IPv4 address is compared to an IPv6 address or used in a mixed-family zone, the IPv4 address is handled as IPv4-mapped IPv6. If you create a mixed-family zone, some users may find results of this mapping as unexpected. Micro Focus therefore recommends creating zones that just contain one type of address.

Zone Attributes
Attribute	Description
Name	A descriptive name for the IP address range the network zone represents (required)
Start Address	Provide an IP address that identifies the start of the network scope.
End Address	Provide an IP address that identifies the end of the network scope.
Dynamic Addressing	Click this option on or off to indicate whether this network uses dynamic addressing Checkmark (toggle on) this option to indicate that the network you are describing *uses dynamic addressing* (Dynamic Host Configuration Protocol or DHCP server) Leave this option unchecked (toggle off), if the network you are describing does not use dynamic addressing (but, rather, *uses static IP addresses*)
Location	The location resource for this zone. See Locations. Select the location using the drop-down arrow. The arrow displays the Locations resource tree. Alternatively, if the resource tree has too many subgroups to traverse and you know the location by name, see Using the Advanced Selector While Editing Resources.
Network	The network in which this zone resides. Select the zone using the drop-down arrow. The arrow displays the Zones resource tree. Alternatively, if the resource tree has too many subgroups to traverse and you know the zone by name, see Using the Advanced Selector While Editing Resources.

In addition to the above zone Attributes, the Zone Editor includes subtabs for adding Assets and Categories into the zone you are configuring.
