If none of the matched policies has a free IP address, the server will drop the client packet and log an event. If no IP addresses are free from any of the address ranges associated with the policy, the server will process the next matched policy as defined by the processing order. If no IP addresses are available to use from the lower address range, the server will then look for a free IP address from the higher address ranges. If a policy is associated with multiple address ranges, the server will assign IP addresses by first attempting to assign an IP from the lowest address range. If a client request matches the conditions of a policy for which a specific IP address range is associated, the server will assign the first free IP address from the range as determined by the rule. A single client request can match multiple policies. The policies applicable at a scope are those configured at the scope and those inherited from the server. Once the server determines the client scope, the server evaluates the DHCP packet against the policies applicable for the scope in the processing order specified. The DHCP server determines the scope to which a DHCP client belongs based on the gateway IP address of the relay agent or the interface of the DHCP server on which it receives the DHCP client packet.
If there are no policies defined at the scope level, the policies at the server level apply to the scope. The processing order for a scope level policy defines the order of evaluation within the scope.
If policies exist at the server and scope levels, the server applies both sets of policies and evaluates the scope policies before the server policies. The DHCP administrator assigns the processing order to the policies. The DHCP server evaluates policies sequentially according to an assigned processing order. Vendor specific DHCP options: One or more vendor specific DHCP options to send to the client based on the vendor class field in the client request. Standard DHCP options: One or more standard DHCP options to send to a client in the response based on the options requested by the client in the parameter request list. A server level policy cannot have a setting for an IP address range. IP address range: The IP address range within a scope from which to assign an IP address to a client. The following fields in the DHCP client request are available when defining policies. An administrator wishing to route traffic on the network differently for VMs can create a policy based on MAC address prefix to assign a short lease duration, specific IP address range, and different default gateway. Virtual machines are added and removed dynamically depending upon load requirements at a given time. Virtualization: A data center network employs virtualization for different workloads and applications. Servers can be assigned a 12-day lease duration Similarly, a server policy can be created using a list of server MAC addresses.

DNS dynamic update protocol can be disabled for clients matching this policy. All the wireless clients that connect via a specific relay agent can be assigned a four-hour lease duration. Depending on the type of client, the administrator might wish to provide different lease duration settings. Multiple roles: A network includes different types of computers, such as laptops, desktops, and servers in the same subnet. IP Phone CP-7940G and configure printer and IP-phone policies to assign a specific IP address range to these devices. For example, you can add a vendor class of “Hewlett-Packard JetDirect” or Cisco Systems, Inc. This enables router policies and quality of service (QoS) based on IP address range policies to control network access or traffic. Administrators need the ability to classify these devices using different IP address ranges. Multiple device types: A network includes many different DHCP client devices, such as printers, IP phones, and desktops. Policy based assignment enables flexibility for some common scenarios, including: A policy contains a set of conditions to evaluate when processing client requests. With a DHCP server running Windows Server 2012 or Windows Server 2012 R2, administrators can define an address assignment policy at the server level or scope level. The configuration, including IP addresses and all other configuration parameters, is designed only to work on a separate test lab network.
This configuration is neither designed to reflect best practices nor does it reflect a desired or recommended configuration for a production network. Individual computers are needed to separate the services provided on the network and to clearly show the desired functionality. The following instructions are for configuring a test lab using the minimum number of computers.
