DHCP Vendor-Specific and Class ID Option Support


In Windows Server 2003, DHCP supports vendor-specific defining of options. When an option is identified as vendor-specific, DHCP looks up the configuration as specified for the specific vendor. This feature enables the quick introduction of compelling custom applications for enterprise networks. Equipment from multiple vendors on a network can also use different option numbers for different functions. RFC 2132 describes the vendor class and vendor options.

Most implementations of DHCP treat clients equally, rendering the server unaware of the specific types of clients with which it interacts. This behavior necessitates a common configuration issued by the server to all DHCP clients. It also restricts the server to assigning only an address from a scope, along with the options available within that scope.

In Windows Server 2003, the implementation of user classes allows DHCP clients to distinguish themselves by specifying a client type, such as a desktop or laptop. An administrator can then configure a DHCP server to assign different options, depending on the type of client receiving them. For example, the server could assign short leases to laptop clients, while desktop clients on the same network might require other settings. User class support gives administrators greater flexibility in configuring clients.

Vendor and user classes are made available for use by DHCP clients and servers in a variety of ways. The following table compares and contrasts the features of these classes.
