Dynamic Host Configuration Protocol (DHCP)

Dynamic Host Configuration Protocol (DHCP) is a core network service that allocates network addressing dynamically to clients as they shift from one network to another, or static entries for clients that have a specific requirement to always be on the same network address. This service automatically configures clients with network information including IP address, subnet mask, gateway, the proper Domain Name Servers (DNS), and boot-time configuration servers (e.g., PXE Boot and Bootp services) if available. All devices connecting to the wired network in University residences or to the University’s wireless network are required to use DHCP. Increasingly all desktop clients throughout the University with a static IP allocation requirement will be migrated to utilize DHCP for their allocation.

Benefits

DHCP enables devices such as computers and mobile devices to obtain their dynamic network configuration automatically upon connection to the University’s wired or wireless network. DHCP allows you to move these devices from place to place without making any configuration changes.

Key Features

• facilitates client mobility
• eases computer administration by dynamically providing network information
• provides a mechanism to seamlessly change local network information
• can direct systems to configuration services, such as PXE Boot and Bootp, during start-up

What to Expect

This service normally will be available 24 by 7 except for standard change windows, as described in IS&T’s standard policies, procedures, and schedules for making changes.

Requirements

Clients must have a DHCP-capable TCP/IP stack running on their network device and must be configured to use DHCP.

Getting Started

• Contact us if your department or research group has specific questions regarding the local configuration of DHCP, including information about boot-time configuration services.
