What data is collected by this process, and how is it used?

Network registration associates a device's MAC address with an OHIO ID.  It does not install any tracking software, does not collect personal data, and does not grant the university access to the device or its hard drive.
The list of MAC addresses and OHIO IDs will be used by a limited number of authorized individuals in the following situations:

  • Official investigations
  • Network troubleshooting & configuration
  • Security incident responses

Common troubleshooting tips

Having Difficulties? Try these troubleshooting tips…

  • SYMPTOM: You are unable to get to the Internet on your browser and it does not redirect you to the network registration page.
    PROBABLE CAUSE: The DNS settings for your network adapter may be statically set.
    ACTION: Ensure the DNS settings for the network adapter are set to “automatically receive from the DHCP server”.
  • SYMPTOM: After entering your credentials on the Login page and clicking “Log In”, the login page reappears.
    PROBABLE CAUSE: Cookies are not enabled on the browser.
    ACTION: Enable cookies on the browser under browser settings (Note that this varies from browser to browser).
  • SYMPTOM: When you enter your credentials on the Login page and hit Enter on the keyboard, you receive the message that says “Make sure that your cookies are enabled…”
    PROBABLE CAUSE: Cookies are either not enabled, or are not submitted properly to the browser.
    ACTION: Refresh or close the browser and try again; click on the “Log In” rather than using “Enter” on the keyboard.
  • SYMPTOM: After you successfully registered your device, your browser keeps redirecting you to the network registration page that says that your device is successfully registered.
    PROBABLE CAUSE: The device has not been rebooted after registration.
    ACTION: Shut down the device completely and restart it.
  • SYMPTOM: After registering your device, you can browse the internet but are unable to connect to shared drives or Exchange.
    PROBABLE CAUSE: The device has not been rebooted after registration.
    ACTION: Shut down the device completely and restart it.
  • SYMPTOM: Your browser opens with many browser tabs, but does not display the Network Registration page.
    PROBABLE CAUSE: The network registration page is open but is not on the current tab.
    ACTION: Check each tab to locate the network registration page; or, close the browser and reopen with just one tab.
  • SYMPTOM: Following the registration process, you see a web page that just has the title “Network Registration.”
    PROBABLE CAUSE: Your device is probably registered, but the confirmation screen is not displaying.
    ACTION: Refresh the browser and you should see the message “Your device is successfully registered…”

What is a MAC Address?

A MAC address is a series of 6 number/letter pairs that uniquely identifies the network hardware inside a device. It usually looks something like:

01-23-45-67-89-AB or 01:23:45:67:89:AB 

Only the numbers 0-9 and letters A-F are used, so take care not to confuse a zero with the letter "O."

MAC addresses are set at the factory, one per network adapter.  If a device has more than one adapter, then it will have more than one MAC address.  For example, most laptops have two MAC addresses - one for Ethernet and one for wireless.

If you are manually registering a device with both wired and wireless adapters, make sure to choose the MAC address for the wired/Ethernet adapter. 

Some manufacturers refer to a MAC address as a hardware address, burned-in address (BIA), or physical address.

Does registering my device open it up to tracking or content scans?

Registering a device on our network is similar to signing in to a cable modem at home or a secure Internet hot spot at a business or another university.  Before a machine is allowed on our network, it must be registered to your OHIO ID to prove that it belongs to a current student, faculty, staff, or sponsored guest.  

No tracking software or agents are installed on your computer, and network registration does not allow any special access to your system.  

If your device is infected with a virus or has an open security hole in its operating system, then the network may place your device in quarantine and display a web page that will help you fix that problem.

How do I register a device if it does not have a web browser?

The device can be registered using the Web Registration Tool.  To access the Web Registration Tool, you will need to use a web browser from a device that has access to the network.

How do I register an Xbox or Apple TV?

I have registered my device, but my browser points to a page that says “Remediation Pending”

If you see this page, it means that security scanning has determined that some action is required on your part for this device to continue to have network access. Follow the steps below:

  • Write down the actions recommended in the “Reasons/Comments/Instructions” field.
  • Click the Continue button 
  • Agree to Computer and Network Use policy
  • Once you see the confirmation that your device is registered, close the browser and reboot your device by turning the power off and then back on to begin using the network. 
  • After rebooting, open a web browser and if the browser does not bring up your normal home page, please clear the browser cache and reload the web page.
  • Make sure that you follow the recommended actions to continue to stay on the network.

How do I register a device with a static or reserved IP Address?

If your device has a static or reserved IP address that was assigned by OIT, then that device is already registered.  

If you wish to register a new device that requires a static address, please contact the Service Desk to request a reserved address.

Do I need to renew network registration for my device?

Yes. You will be sent a reminder notification to renew your device.

  • Students will be required to renew their registration at the beginning of each academic term.
  • Faculty and Staff will be required to renew their registration once every year.

What options are available for lab managers?

Faculty and staff who are responsible for large numbers of network devices (computer labs, large research installations, etc.) who do not wish to use the Web Registration Tool or the automated process can place a request with the OIT Service Desk at 740-593-1222 or www.ohio.edu/oitech to register those devices in bulk.  

You will need to have a list of MAC addresses and descriptions available when you contact the Service Desk.

Do I have to install any software on my device?

No. Network registration does not install or require you to download any additional software on your device.
