education university research legacy

The campus network of Johns Hopkins University in Baltimore, Maryland, one of the

United States' foremost research universities, under the handle JHU.

What it's used for

  • Connectivity for the university's schools, libraries and research groups on the legacy 128.220.0.0/16, alongside 162.129.0.0/16 and several 198.57.x blocks used by its medical and health-system estate.
  • Backs a very large research computing footprint, plus IPv6 out of a /32.

Notable

  • Institutional address space serving students, faculty, hospitals and labs, not paying subscribers.
  • Johns Hopkins consistently ranks first among US universities in research spending, and the size and spread of the address space reflect a network that has to serve both a campus and a large academic medical enterprise.
