Enabling and Disabling IPv6 on PCs


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 attempting to modify a system's network settings. To verify whether a PC is already actively using IPv6, use a web browser to navigate to http://test-ipv6.com.

IPv6 Connectivity Test

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