About this network

HINES — the Hokkaido University Information Network System, the campus network of Hokkaido University in Sapporo, one of Japan's national universities.

What it's used for

• Campus networking for Hokkaido University: faculties, laboratories, libraries, the university's computing centre and student services.
• Research and academic traffic, reaching the wider internet and Japan's academic networks.

Notable

• Announces the legacy class-B blocks 133.87.0.0/16 and 133.50.0.0/16 — the 133/8 range is the classic Japanese academic allocation, and a pair of /16s reserved for one university is a signature of an early institutional holder.
• rDNS confirms the campus directly: hosts resolve under hokudai.ac.jp, including hucc.hokudai.ac.jp (the university's information initiative / computing centre).
• Institutional address space, not consumer or hosting. Its addresses belong to staff, students and lab equipment on campus.
