Solaris Zones is a software partitioning technology, which provides a means of virtualizing operating system services to create an isolated environment for running applications. This isolation prevents processes that are running in one zone from monitoring or affecting processes running in other zones.
You can configure non-global zones with a shared-IP address or an exclusive-IP address. The shared-IP zone shares a network interface with global-zone and the exclusive-IP zone does not share network interface with global-zone.
See the Oracle Solaris Administration: Oracle Solaris Zones, Oracle Solaris 10 Zones, and Resource Management Solaris operating environment document.
Oracle provides regular updates and patches for the Oracle Solaris Zones feature. Contact Oracle for more information.
