Summary

University of Nagasaki

Japan · AI-generated

education university

The University of Nagasaki (Nagasaki Prefectural University) is a public university in Sasebo, Nagasaki Prefecture, Japan, formed in 2008 from the merger of Siebold University of Nagasaki and the former Nagasaki Prefectural University.

What it's used for

  • Campus, research, and administrative networking for the university's faculties and students.

Notable

  • A small allocation for a single-institution campus network — addresses here are institutional, classified education rather than commercial hosting.
  • Distinct from Nagasaki University, the separate national university in the same prefecture.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
