AS63785 FU-NTP Fukuoka University
Unclassified RIPE Educational/Research
Summary
Fukuoka University
education research ntp
FU-NTP is operated by Fukuoka University.
What it's used for
- The space carries university infrastructure, specifically a public NTP service as indicated by the PeeringDB description and the handle name.
- The inventory consists of 512 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with 2 observed neighbours, indicating a small-scale internal or service-specific network rather than a transit provider.
- Traffic from this AS consists of research and educational endpoints, specifically time synchronization services for the university community.
Notable
- Registrants for the announced IPv4 prefixes are listed as Japan Network Information Center (JPNIC), which is the regional internet registry for Japan, consistent with the holder being a Japanese institution.
- Fukuoka University is a private research university in Fukuoka, Japan, with approximately 20,000 students.
- The address inventory is small and finely subdivided, typical of a specific departmental or service allocation within a larger institutional estate.

Interconnection

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 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
