Register your wired device on the IU network

On this page:


Before any wired (Ethernet-connected) device can establish an internet connection via the network at Indiana University, its network adapter(s) must be registered with IU's DHCP service. On campus, you can make a limited connection to IU's network to visit the DHCP registration page and register your device. After doing so, you'll have full internet access. For more information specific to Bloomington residences, see Ethernet cables for Bloomington residences.

  • In most cases, faculty and staff will have their IU-owned work computers and networked devices registered by their departmental or school-based IT Pros. However, faculty and staff can visit the DHCP registration page to register personally owned Ethernet-enabled devices they bring to campus (if the devices meet system requirements). See below for more about the DHCP registration page.
  • Devices that are running outdated operating systems or that otherwise do not meet IU's security standards cannot be registered.

If you need help, have a question, or want to report a problem, contact your campus Support Center, or the IT Pro for your department or school.

To learn the name of your department's IT Pro, consult your supervisor, your departmental website, or IT People. If you still cannot identify your IT Pro, call the UITS Support Center at 812-855-6789 (Bloomington) or 317-274-4357 (Indianapolis).

Ethernet cables for Bloomington residences

The Ethernet cables required for Bloomington dorms depends on the location. Some use standard commercial Ethernet cables, while others require special IU-proprietary Ethernet cables. If your room does not have an IU-Ethernet cable, you may obtain one from the TCC desk (fourth floor of the Wells Library West Tower).

Use the DHCP registration page

Students, faculty, and staff can register personally owned computers running Windows or macOS, most Linux computers, gaming devices with a built-in browser, and other supported Ethernet-enabled devices via IU's DHCP registration page.

To do so, you must first connect the computer or device (using an Ethernet cable or wireless) to the IU network.

You must use an Ethernet cable or IU PublicNet wireless to connect supported gaming consoles to the IU network. (Most gaming consoles do not support the Wi-Fi Protected Access II (WPA2) Enterprise security protocol, and consequently cannot authenticate or connect to eduroam or IU Secure.)

Once your device is connected to the IU network:

  1. Open a web browser. Your browser should be redirected automatically to IU's DHCP registration page; if it isn't, enter this URL:
  2. On the registration page, read the provided information, and then click Continue.
  3. Log in with your IU username and passphrase.
  4. Read the user agreement. You must agree to the user agreement to proceed. Click I agree.
  5. To finish the registration process, click Register Now.

The DHCP service can take up to five minutes to process your registration. You should wait at least that long, and then restart your computer or device.

If you are unable to complete the online registration process, contact your campus Support Center to request manual registration. Before contacting the Support Center, make sure you can provide the required information, as noted in the following section.

Manual registration by a consultant

UITS must manually register certain computers and networked devices, such as:

  • Internet-capable televisions
  • Gaming devices without a built-in browser

Consultants can also manually register your device if you are unable to complete the online process via the DHCP registration page.

Contact the Support Center to request manual registration, providing:

Re-register your computer or networked device

In some cases, you may need to re-register your computer or networked device; for example:

  • To ensure the security and integrity of the IU network, UITS periodically purges old or unused network registrations. UITS also purges network registrations in the halls of residence on a rolling basis each fall semester.
  • The University Information Policy Office (UIPO) and the University Information Security Office (UISO) can disable any IU user's access to the IU network for security reasons or policy violations. In such cases, UIPO will notify affected users via email.

If your device's network registration has been purged, the device will not be able to establish an Ethernet connection until you re-register it with the IU DHCP service (using IU's DHCP registration page).

For compromised or vulnerable devices, additional action is required; see If your network access has been disabled by UISO.

Number of networked devices you can register

If you are a campus housing resident, you may register up to five network-enabled devices in your residence.

If you live off campus and are not registering devices for use in campus housing, you may register up to 10 devices.

If you need to exceed the maximum number of registered devices permitted, contact your campus Support Center. If you are a faculty or staff member connecting a device within your school or department, contact the IT Pro who supports your area.

Departmental or school-based IT Pros may register an unlimited number of devices.
