About this network

WISCNET1-AS is WiscNet, the nonprofit research and education network serving colleges, universities, K-12 schools, libraries, and other public institutions across Wisconsin.

What it's used for

• Shared internet access and interconnection for Wisconsin's education, library, and public-sector community, plus links to national research networks.

Notable

• A member-owned regional R&E network (a state NREN), not a commercial ISP. The low AS number reflects an early allocation to one of the internet's first regional academic networks.
