zardoz # cat /etc/hosts
...
127.0.0.1
129.144.10.57 zardoz
129.144.11.83 zardoz-1

zardoz # reboot -- -r
This command rebuilds the device trees so that the system will recognize the
newly installed PCI Ethernet adapter card.
What Next

through this interface, the interface information (its IP address and host name) must
be entered into the namespace on the network name server. For information about
setting up a network name service, consult the Solaris System Administrator
AnswerBook for your specific Solaris release.
