DHCP Technical Reference
Windows Server® 2008 includes Dynamic Host Configuration Protocol (DHCP), a TCP/IP standard that enables the centralized management of IP addresses and other optional configuration information for client computers on a network.
DHCP simplifies IP address configuration by automating the process for clients on a network. DHCP servers allocate IP addresses and related TCP/IP configuration settings to DHCP-enabled clients on the network. DHCP relay agents are used to forward initial DHCP messages between DHCP clients and DHCP servers if the clients and servers are not on the same IP broadcast subnet.
The DHCP Server service for Windows Server 2008 is based on Internet Engineering Task Force (IETF) standards. DHCP specifications are defined in Requests for Comments (RFCs) published by the Dynamic Host Configuration working group of the IETF. The following RFCs specify the core DHCP standards that Windows Server 2008 DHCP supports:
RFC 2131: Dynamic Host Configuration Protocol
RFC 2132: DHCP Options and BOOTP Vendor Extensions
Before you can understand DHCP, you must have a working knowledge of TCP/IP networks. Specifically, you must understand how subnets work within a TCP/IP network. You should also review and understand the terminology found in the What Is DHCP? topic.
