IP Networking in Zones

IP networking in a zone can be configured in two different ways, depending on whether the non-global zone is given its own exclusive IP instance or shares the IP layer configuration and state with the global zone. The shared-IP type is the default.

Exclusive-IP zones are assigned zero or more network interface names, and for those network interfaces they can send and receive any packets, snoop, and change the IP configuration, including IP addresses and the routing table. Note that those changes do not affect any of the other IP instances on the system.
