Summary

Japan · AI-generated

education university research legacy

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.

Education University, school or national research and education network.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,778 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
