For a BOOTP client that runs the Solaris operating environment on an Ethernet network, the client ID is a string derived from the client's hexadecimal Ethernet address, preceded by the Address Resolution Protocol (ARP) type for Ethernet (01). For example, a BOOTP client having the Ethernet address 8:0:20:94:12:1e would use the client ID 0108002094121E.

Select Reserved to reserve the IP address for this client.
