Each non-global zone that requires network connectivity has one or more dedicated IP addresses. These addresses are associated with logical network interfaces that can be placed in a zone by using the ifconfig command. Zone network interfaces configured by zonecfg will automatically be set up and placed in the zone when it is booted. The ifconfig command can be used to add or remove logical interfaces when the zone is running. Only the global administrator can modify the interface configuration and the network routes.
Within a non-global zone, only that zone's interfaces will be visible to ifconfig.
