Summary
This article contains lists of Network IP (Internet Protocol) ranges for the VLAN (Virtual Local Area Network) segments planned at USNH, arranged by campus. The Enterprise VLAN is already in place.
This article also includes USNH guest network traffic rules and limitations. These new Wireless Guest VLAN network segments are being implemented on February 17, 2026.
New Staff, Student, and IoT VLAN network segments will be implemented next month on March 17, 2026. These networks will have no particular limitations except regarding accessing each other. Limitations downstream (like getting into other networks) are still in place just like they are for current wifi.
From Bryan Scovill's email (Monday, February 16, 2026):
- We are firing up the new wireless guest network segments tomorrow (Feb. 17, 2026). We wanted to pass along the rules for your internal documentation.
- Guest network users will get an IP in the 10.(178|179|180).96.0/20 network. That is 10.x.96-111.x.
- The full vlan list is at the end of this[email], with Enterprise and Guest being the ones that are live [as of 2.17.2026] and the other three [Staff, Student, IoT] going live on March 17th.

Important: When a user connects to eduroam with their username in an improper format (like ad\<username>@<campus>.edu or ad\<username>), they end up being treated as a guest. They authenticate, but do not authorize. This is highlighted in the NAC portal, but the impact is not obvious.
- Correct username format to connect to eduroam is: <username>@usnh.edu
Guest Network Traffic Rules
