Purpose
(Optional) Specifies a description of the object group.
You can use up to 200 characters.
(Optional) Specifies the IP address or name of a host.
If you specify a host address, you must use an IPv4 address.
(Optional) Specifies a subnet object.
You must specify an IPv4 address for the network address.
The default network mask is 255.255.255.255.
(Optional) Specifies a nested (child) object group to be
included in the current (parent) object group.
The child object group type must match that of the parent
(for example, if you are creating a network object group,
you must specify another network object group as the
child).
You can use duplicated objects in an object group only by
nesting group objects. For example, if object 1 is in both
group A and group B, you can define a group C that
includes both A and B. However, you cannot include a
group object that causes the group hierarchy to become
circular (for example, you cannot include group A in group
B and then also include group B in group A).
While you can have an unlimited number of nested levels
we recommend a maximum of two levels.
