education research legacy

BRUWS-AS3128 is held by the University of Wisconsin System, the state's public

university system spanning UW-Madison, UW-Milwaukee, and the regional

universities across Wisconsin.

What it's used for

  • Campus and research networking for the UW System's institutions: academic and administrative systems, residence halls, labs, libraries, and public-facing university services.

Notable

  • The announced space is unusually large for a single institution, running to several legacy /16s and over half a million IPv4 addresses. That scale is a signature of early university allocations, when a campus could ask for a Class B and get one.
  • Institutional address space: IPs here map to university buildings and systems, not to residential subscribers or hosting customers. ARIN registered the ASN in 1993.

Interesting

  • Wisconsin's state government runs its own separate network on [AS3136](https://asn.ipinfo.app/AS3136), registered just two days later in the same 1993 batch.
