This topic provides overview information about the Dynamic Host Configuration Protocol (DHCP) Server role in Windows Server® 2012.
DHCP is an Internet Engineering Task Force (IETF) standard designed to reduce the administration burden and complexity of configuring hosts on a TCP/IP-based network, such as a private intranet. Using the DHCP Server service, the process of configuring TCP/IP on DHCP clients is automatic.
Windows Server 2012 provides several enhancements to the DHCP Server service. For more information about what’s new in DHCP for Windows Server® 2012, see What's new in DHCP.
DHCP in Windows Server 2012 provides the following:
Safe, easy and reliable: Valid configuration parameters for all clients on the network can be dynamically provided. DHCP clients renew their leased address allocation automatically in the background. With DHCP failover, a new feature in Windows Server 2012, DHCP servers can provide a highly resilient DHCP service that allows the DHCP client to extend the lease on its current IP address by contacting another DHCP server on the enterprise network.
Flexible assignment: DHCP supports a large and extensible set of client configuration parameters. With client reservations, it is possible to reserve a specific IP address for permanent use by a DHCP client. A new feature in Windows Server 2012 called policy based assignment allows for even greater flexibility.
DHCP integration with DNS enables DNS resource records to be dynamically updated for new computers and devices, or when IP addresses of existing devices change on the network.
Installation of the DHCP Server role can be performed using Server Manager. The following features and tools are installed automatically when you install DHCP Server:

Remote Server Administration Tools
DHCP Server Tools are required to manage the DHCP Server role, but do not have to be installed on the same server. The DHCP Management console is installed automatically when you install DHCP Server unless you choose to cancel installation of Remote Server Administration Tools.
