The DHCP client is the dhcpagent daemon. If you install Oracle Solaris by using the LiveCD GUI installer, then the DHCPv4 and DHCPv6 protocols are enabled on the installed system. If you install Oracle Solaris by using the text installer, you are prompted to select how the network should be configured on the installed system. If you specify Automatic Network Configuration, then the DHCPv4 and DHCPv6 protocols are enabled on the installed system.
You do not need to do anything else with the Oracle Solaris client to use DHCP. The DHCP server's configuration determines what information is given to DHCP client systems that use the DHCP service.
If a client system is already running Oracle Solaris, but not using DHCP, you can reconfigure the client system to use DHCP. You can also reconfigure a DHCP client system so that it stops using DHCP and uses static network information that you provide. See Enabling and Disabling a DHCP Client for more information.
