Frequently Asked Questions about Network Registration

Tags netreg


Who Needs to Register?

Anyone attempting to plug into and use the wired campus network will need to be registered in order to use the network. Computers connected to the VPN or those that have static IP addresses are already registered.

Who Is Allowed to Use the Wired Network?

You must be affiliated with the college (faculty, student, and staff) and be able to provide campus credentials (your NetID and password) to register.

A capability also exists to register guests on the wired network for short periods of time. Please work through Guest Connection to Wired Network to do this.

Why Do I Have to Register to Use the Ethernet Network?

Under the terms of the Communications Assistance for Law Enforcement Act (CALEA), Dartmouth selected the option of modifying the campus network to an architecture that is considered a “private network”. As a result, we implemented access controls for users that are attaching to the campus network. Users must be affiliated with Dartmouth College in order to use the campus network.

Who Has Access to This Information?

Each user can access and manage their own registration data at

Only authorized Information, Technology & Consulting (ITC) staff will have access to all the registration data. This information will only be shared outside of the authorized group when required by law enforcement.

How Are Off-campus Students/Visitors Affected?

Registration of the wired network does not affect off-campus users; it only impacts people when they plug an Ethernet cable into a campus network port. If a visitor arrives on campus and plugs into a campus Ethernet port, they will be routed to our registration page. Since they will not have valid credentials, they will not be able to register. Visitors to campus should use “Dartmouth Library Public” or "Dartmouth Public" on our wireless system or a public computer in the Library to gain access to the Internet. Any valid Dartmouth user can also register a computer for a visitor.

If I Only Use the Wireless Network, Do I Need to Register?

No, the network registration system only affects the “wired” network. Only computers that use an Ethernet cable to plug into a network jack are required to be registered.

I Got a New Computer. How Do I Transfer the Registration from My Old Computer?

There is no need to transfer registrations from one computer to another. A user may have multiple computers registered under their name. A user can always contact the IT Service Desk at 603-646-2999, send e-mail to, or contact their IT support office to have old registrations deleted from the system.

How Do I Register a Device Other Than a Computer or a Device That Doesn't Use a Browser to Use the Ethernet Network?

Examples: gaming consoles, robotic devices, lab equipment, building sensors, routers

If you have a device that needs to use the wired network and the device does not support a web browser, go to In the Registrations section on the right, click Add Device. Enter the Hardware Address (MAC address) of the device that needs to have access and a Description of that device, then click Add Device. Steps for finding the MAC address are at the bottom of this article.

What Computers Need to Register?

If you have a static IP address for your server or computer or your computer is using a VPN connection, you do not need to register.
Any computer that plugs into the wired network and uses DHCP (dynamic host communications protocol) to obtain a network address will need to register.

Will My Registration End When I Turn My Computer Off?

Registrations (except guest registrations) are valid until you leave Dartmouth College, so if you shut your computer off it is still registered and can use the network until your account is inactivated.

What If Someone Else Uses My Computer? Do They Have to Register It Too?

Once a computer is registered to the network anyone can use the computer to access the network as long as the account of the person who registered the device remains active.

How Many Computers Can One Person Register on the Network?

There is no limit to the number of computers a user may register.

If I Have Problems Registering, Who Can Help Me?

The IT Service Desk and your department’s computing support staff are available to assist anyone having a problem registering a computer. Please contact the IT Service Desk at 603-646-2999, send e-mail to, or contact your department's IT support office if you need assistance.

How Do I Unregister a Computer?

Each user can access and manage their own registration data at Please contact the IT Service Desk at 646-2999, send e-mail to, or contact your department's IT support office if you need assistance unregistering a computer.

Do I Need to Install Any Software on My Computer In Order to Register It?

There is no software required to use the registration system. Registration of computers is completed through the use of a web browser.

Is There a Way to Support Guests?

This registration process only impacts the wired network. If a visitor requires network access and they use wireless, they can use the Dartmouth Library Public (if in a Library) or the Dartmouth Public wireless networks. If a guest needs to access the wired network, any valid Dartmouth user can temporarily register the guest computer. A sponsor within a department can register a computer for a guest visitor. There will be a description field available so a sponsor can enter some information to identify sponsored computers and have the sponsored computers registration automatically expire after a certain time period from the registration system. 

I’m Registering Computers for My Department. How Do I Do That?

On the registration page there will be a box for supplying general information. For most users, it is a description of the machine they are registering so they can easily identify the device later. This space should be used by an individual that is registering department or lab computers; they should enter the contact information for the department or lab.

I Was Not Prompted to Register. Is It Because I'm Running a VPN?

If you automatically start a VPN connection each morning, your computer will have connectivity via the VPN connection. You should disconnect from the VPN, then start your web browser and register your computer, then restart your VPN connection.

I Am Registering a Device to Be Used on the Network, But Not from That Device. The Registration Process Is Asking for the Hardware (MAC) Address. How Do I Find That?

This information should be found on the FCC label on any electronic device. On many devices (computers, game consoles, phones) it is found under the battery. It is often found in the format 00:00:00:00:00:00 - with the zeros being any combination of numbers and letters. Note that some manufacturers do not include the colons between the numbers.

On a Windows computer, you can also find the hardware address by clicking Start then Run. In the Open box type cmd and press Enter. In the window that appears, type ipconfig /all and press Enter. The hardware address is found in the "Physical Address" field in the "Ethernet adapter Local Area Connection" section. It will be in the format of 00-00-00-00-00-00. You may need to replace the hypens (-) with colons (:) when entering this information in the Hardware Address field on the "Register a new device" page.

On a Macintosh computer, you can find the hardware address (MAC address) by clicking About this Mac found under the Apple menu. Click either System Report... or More info (depending on the version of your Operating System), then Network in the Contents column that appears in the left side of the window. Click Ethernet or Built-in Ethernet in the Active Services column. The MAC address, along with other information, appears in the lower half of the window. The MAC address will be in the format of 00:00:00:00:00:00 where the zeros can be letters or numbers. Do not use the values for the 'ARPResolvedHardwareAddress' field. Look for the Ethernet "MAC Address".
