Enabling and Disabling IPv6 on PCs

Overview

IPv6 is the next generation of Internet transport protocol. Most Internet traffic today uses IPv4. However, IPv6 Internet traffic is growing rapidly, and it will eventually supersede and replace IPv4. All key components of the University network infrastructure support both IPv4 and IPv6 traffic

These instructions explain how to enable and disable IPv6 on PCs running the latest versions of Windows, MacOS, and Red Hat Linux.

Checking IPv6 Communication

It is important to check a PC's IPv6 functionality before making any attempts to modify a system's network settings. In order to verify whether a PC is already actively communicating on the Internet using IPv6, use a Web browser to navigate to the site http://test-ipv6.com.

 

This test site will return a fully-qualified IPv6 address in the second Summary bullet point as well as a score of 10/10 on systems successfully communicating via IPv6.

 

Enabling and Disabling IPv6 on Windows 10

  1. Select the Settings option via the Start menu.
  2. In the Settings window, click once on Network & Internet.
  3. In the Network & Internet window, click once on Ethernet if you wish to check the IPv6 status of your Ethernet (wired) network status.

You may need to use the scroll bar on the side of the section in order to see TCP/IPv6 line. Clicking the check box on the IPv6 line so that the box is empty will disable IPv6 on the system. Clicking it so that the box is checked will enable IPv6.
  6. Click OK to close the Properties box.

Enabling and Disabling IPv6 on Windows 8

  5. Right click on the Local Area Connection icon to bring up a Properties menu. If the system is connected to PittNet via wireless, right click on the wireless network connection icon.
  6. In the Properties box, the Networking tab should be prominent. An entry for Internet Protocol Version 6 (TCP/IPv6) should be visible in the This connection uses the following items section of the Properties box. Clicking the check box on the IPv6 line so that the box is empty will disable IPv6 on the system. Clicking it so that the box is checked will enable IPv6.
  7. Click OK to close the Properties box.

Enabling and Disabling IPv6 on Windows 7

  1. Select Control Panel from the Start menu.
  2. Click on Network and Sharing Center.
  3. Click Change adapter settings.
  4. Right click on the Local Area Connection icon to bring up a Properties menu. If the system is connected to PittNet via wireless, right click on the wireless network connection icon.

An entry for Internet Protocol Version 6 (TCP/IPv6) should be visible in the This connection uses the following items section of the Properties box. Clicking the check box on the IPv6 line so that the box is empty will disable IPv6 on the system. Clicking it so that the box is checked will enable IPv6.
  6. Click OK to close the Properties box.

 

Enabling and Disabling IPv6 on MacOS

Note: These instructions have been tested with MacOS 10.9 (Mavericks). Testing by CSSD has determined that older versions of the MacOS may not offer the same level of IPv6 functionality as MacOS 10.9.

  1. Click on System Preferences in the dock.
  2. Select on Network option.
  3. If your system connects to PittNet with an Ethernet cable, click once on the Ethernet choice in the list of network interfaces along the left side of the Network window. If the system is connecting to Wireless-PittNet, click once on the Wi-Fi selection.
  4. Click the Advanced button. A tabbed presentation of network adapter settings should appear with TCP/IP prominent. If it is not, click once on the TCP/IP icon that runs along the top of the section.
  5. To disable IPv6, change the Configure IPv6 option to Link-local only.
    To enable IPv6, make sure that the Configure IPv6 option is set to Automatically.
  6. Click OK to exit the adapter configurations window and then Apply.

Enabling and Disabling IPv6 on Red Hat Enterprise Linux 7
