education university research legacy

CITYUNI-AS-AP is City University of Hong Kong (CityU), a public research

university in Kowloon Tong, Hong Kong.

What it's used for

  • Campus networking for students, faculty, and staff: teaching, research, library, residence halls, and administrative systems.
  • Research and inter-university connectivity within Hong Kong's academic networking community.

Notable

  • This is institutional address space. Traffic from it is overwhelmingly campus users rather than commercial subscribers or hosted customers.
  • The allocation is sizeable for a single campus (tens of thousands of addresses), reflecting an era when universities received generous IPv4 assignments.
