Dynamic IP Connections (DHCP)

This article explains the use of DHCP on campus.

Dynamic Host Configuration Protocol (DHCP) allows a computer to receive its IP address, gateway and name servers automatically when it connects to the network, bypassing the need for a user to reconfigure that information at each new location.

Each computer or other device connected to the University of Chicago network needs an IP address in order send or receive information on the network. In many areas of campus and all of the residence halls, an IP address is automatically available when the computer is physically connected to a jack. This is known as DHCP (Dynamic Host Configuration Protocol). If you need to manually register an address, you may use the DHCP Manual Network Registration form.

The University of Chicago provides DHCP to the residence halls, the wireless network and subnets in several buildings including Stuart, Walker, the Chicago Theological Seminary and Center for Integrative Science. DHCP is also available in several public areas in libraries and commons.

Many departments also provide DHCP locally. Any questions or concerns about DHCP provided by others than IT Services should be addressed to the administrators of that system.

IT support groups who would like to use IT Services' DHCP service should send email to to arrange for that service.

Using IT Services' DHCP

  • Make sure your computer is set to be configured via DHCP.
  • Open a web browser and go to any website.
  • You will be automatically redirected to a login page.

  • Once you have authenticated, you will need to reboot your machine.
  • Until required to re-authenticate, you may access the network through any TCP/IP application (web browser, ssh client, mail client, etc).
  • Authentication for DHCP is required annually.
