4.16.1.1 DHCP Client
DHCP protocol is used for (workstations and servers) TCP/IP network hosts
connection parameters dynamic configuration. UDP/IP protocol is used as a
transport protocol. Host which requests data for its network connection
configuration (IP-address, subnet mask, default gateway etc) is called
DHCP-client. IP-address is a basic configuration parameter. After client's start it
sends a DHCP request over the network so it could get a lease of IP-address and
other network parameters. For its identification in its request a client may use
client identifier. In general case, client identifier is a binary set of bytes which is
unique within a physical network segment to which a client is connected. If client
does not provide an identifier, the server will accept client's MAC-address for
network interface. Thus, in DHCP server a client is identified by its identifier and
network interface from which server accepts client's requests (client's interface).
Client's identifier (<CLIENT_ID> parameter in commands) is represented as
ID:<identifier> or 01:<MAC-address of network adapter>.
Example:
ID:01:00:04:35:22:88:1D.
In its requests to the server, a client may indicate its class (class identifier). Class
identifier is a string which defines one of client's properties which is common for a
set of clients. For example, it can be client operating system's name.
