Summary
Cyber Kansai Project (CKP)
research legacy
CKP is the Cyber Kansai Project, a non-profit consortium in Japan's Kansai region (Osaka, Kyoto, Kobe) formed to promote internet technology and its transfer into regional business use.
What it's used for
- Network infrastructure for the consortium and its member organisations.
- Testbed and common-platform work for network applications, in line with the project's stated goal of building shared foundations for business use of the internet.
Notable
- The project's registered contact sits in an academic lab at Kyoto Sangyo University, reflecting its university-plus-industry membership rather than a commercial ISP structure.
- The address footprint is small: this is a consortium's own network, not an access provider selling connectivity at scale.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,784 prefixes, as published 2026-10-19. 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.
