14 +Dynamic Host Configuration Protocol (DHCP) Server in Windows Server automates the assignment and management of IP addresses and related network configurations. By centralizing these tasks, DHCP Server reduces manual effort, minimizes errors, and ensures efficient use of IP address resources across your network.

21 −Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain required TCP/IP configuration information from a DHCP server.

16 +Windows Server includes DHCP Server as an optional networking server role that you can deploy to manage and offer IP addresses leases and other information to DHCP clients. All Windows-based client operating systems include the DHCP client as part of TCP/IP, and DHCP client is enabled by default.

60 +## DHCP Server features

61 +

62 +DHCP Server in Windows Server includes the following features:

63 +

64 +- **DHCP policies**. This feature allows you to create policies that apply DHCP options and setting based on client characteristics, such as MAC address or vendor class.

65 +

66 +- **DHCP audit logging**. This feature allows you to track DHCP server activity, including lease assignments and renewals.

67 +

68 +- **DHCP server management**. This feature allows you to manage DHCP servers using Windows PowerShell, the DHCP console, or the Windows Admin Center.

69 +

70 +- **DHCP server authorization**. This feature allows you to authorize DHCP servers in Active Directory, preventing unauthorized servers from providing IP addresses to clients.

71 +

72 +- **DHCP server integration with DNS**. Dynamic DNS automatically update DNS records when DHCP leases are assigned or renewed, ensuring that clients can resolve hostnames to IP addresses.

73 +

74 +- **DHCP server integration with IPv4 and IPv6**. This feature allows you to assign both IPv4 and IPv6 addresses to clients using DHCP, providing support for both IP addressing standards.

75 +

76 +- - **DHCP failover**. This feature allows two DHCP servers to share a single scope, providing redundancy and load balancing.

77 +

78 +- **DHCP server integration with IPAM**. This feature allows you to manage DHCP servers using IP Address Management (IPAM), providing a centralized location for managing IP address assignments and leases.
