How do I register my wired device on the IU network?
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.
On this page:
- Use the DHCP registration page: To register computers running Mac OS X, Linux computers, gaming consoles, and any other Ethernet-enabled device
- Manual registration by a consultant: Certain computers and devices
- Re-registering your computer or networked device
- How many networked devices can I register?
- 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 running outdated operating systems or otherwise do not meet IU's security standards cannot be registered.
Using the DHCP registration page
Students, faculty, and staff can register personally owned computers running Mac OS X, most Linux computers, 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.
Once your device is connected to the IU network:
- Open a web browser. Your browser should be redirected automatically to IU's DHCP registration page; if it isn't, enter this URL:
- On the registration page, read the provided information, and then click .
- Log in with your Network ID username and passphrase.
- Read the user agreement. You must agree to the user agreement to proceed. Click .
- To finish the registration process, click .
The DHCP service can can take up to five minutes to process your registration. You should wait at least that long, and then restart your computer or device.
Manual registration by a consultant
UITS must manually register certain computers and networked devices, such as:
- Windows computers not running Windows 10, 8.x, 7, or Vista with Service Pack 2
- Internet-capable television devices
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:
- Your building and room number (for Ethernet connections)
- Your Network ID username
- The type of device you're registering (e.g., Linux workstation, Windows Phone, iPad, Kindle Fire, Amazon Fire phone, or Wii U)
- The device's MAC address
To find the MAC address, check the appropriate instructions below, or search the web, consult the manufacturer's technical support, or check with your cellular provider:
- In Windows, how do I find the MAC address of my network adapter?
- In Mac OS X, how can I find the MAC address of my Ethernet or wireless interface?
- How do I determine the MAC address of my Windows Phone?
- How do I determine the MAC address of my Android phone or tablet?
- How do I find the MAC address of my e-reader?
- How do I find the MAC address of my smart TV, DVR, or set-top box?
- At IU, how do I register my gaming console?
Re-registering 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 my network access has been disabled by UIPO or UISO, how can I get it re-enabled?
How many networked devices can I 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.
