ℹ Updated Network Names in Wi-Fi 6 Areas
In areas upgraded to Wi-Fi 6 infrastructure as part of Pitt Digital's ongoing network modernization initiative, select these updated network names when connecting new devices:
- PittNet (alternative to WIRELESS-PITTNET)
- Pitt Guest Wi-Fi (alternative to PITT GUEST WI-FI)
Both current and legacy network names will continue to function until Pitt Digital communicates retirement timelines with ample advance notice.
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.
Detail
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 the Test your IPv6 website.
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.

Enabling and Disabling IPv6 on macOS
Note: These instructions have been tested with macOS 10.9 (Mavericks). Testing by Pitt Digital has determined that older versions of the macOS may not offer the same level of IPv6 functionality as macOS 10.9.
