public class ClientIdentifier
extends DhcpOption
This option is used by DHCP clients to specify their unique
identifier. DHCP servers use this value to index their database of
address bindings. This value is expected to be unique for all
clients in an administrative domain.
Identifiers SHOULD be treated as opaque objects by DHCP servers.
The client identifier MAY consist of type-value pairs similar to the
'htype'/'chaddr' fields. For instance, it MAY consist
of a hardware type and hardware address. In this case the type field
SHOULD be one of the ARP hardware types defined in STD2. A
hardware type of 0 (zero) should be used when the value field
contains an identifier other than a hardware address (e.g. a fully
qualified domain name).
For correct identification of clients, each client's client-
identifier MUST be unique among the client-identifiers used on the
subnet to which the client is attached. Vendors and system
administrators are responsible for choosing client-identifiers that
meet this requirement for uniqueness.
The code for this option is 61, and its minimum length is 2.
