education university research legacy

USF is the University of South Florida, a large public research university in

Tampa, Florida. AS5661 is its campus network, an ARIN allocation dating to 1995.

What it's used for

  • Carrying traffic for USF's campuses, research computing, and university services out of the legacy 131.247.0.0/16 block, alongside an IPv6 /32.

Notable

  • An institutional network, not a commercial one: addresses here belong to campus workstations, labs, residence halls, and university-run services rather than paying subscribers.
  • The whole of a class-B network sits behind this ASN, a size of allocation that was routine for universities in the early internet and is rarely granted now.
