  Q: Can zones in one computer communicate via the network? A: Both shared-IP and exclusive-IP zones can communicate via the network. In general, a zone is assigned to use one or more network ports (aka NICs), and network traffic to or from other computers uses the assigned NIC(s), following standard IP rules. Network traffic between two zones on the same system may require extra planning.
