Summary
The Chinese University of Hong Kong (CUHK)
education university research legacy
ERX-CUHKNET is the campus network of The Chinese University of Hong Kong, one
of Hong Kong's major research universities.
What it's used for
- Campus, research, and administrative networking for CUHK, including faculties, research institutes, libraries, and student residences.
- Onward connectivity for the university into Hong Kong's academic and commercial internet exchanges.
Notable
- The
ERX-prefix marks this as an Early Registration Transfer record: the allocation predates APNIC's authority over the region and was later moved from the ARIN-era registry into APNIC's care. - University address space is institutional — labs, offices, and campus Wi-Fi rather than residential subscribers.
Interesting
- Hong Kong's universities were among the earliest Asian institutions on the global internet, which is why one of them holds a number this far down the range.
