Summary
ASTEM Kyoto (Internetwork Kyoto)
education research legacy
IP-KYOTO — Internetwork Kyoto, the network run by ASTEM, the Advanced Science, Technology & Management Research Institute of Kyoto: a public-interest foundation backed by Kyoto City that supports research, startups and regional industry.
What it's used for
- Kyoto-Pnet, a corporate internet-connectivity service that has run since 1995 for companies and organisations in the Kyoto area.
- Univnet, network service for universities in Kyoto.
- ASTEM's own research and administrative infrastructure (
ip-kyoto.ad.jp).
Notable
- Announces
163.208.0.0/16, a legacy class-B — a size no modern regional network would be allocated, and a marker of a mid-1990s institutional holder. - Most hosts that resolve do so under
picky.or.jpwith names of the formflt-NNN-NNN.picky.or.jp, indicating members attached over NTT FLET'S access lines rather than a consumer subscriber pool. - A hybrid: part regional academic network, part civic/industrial connectivity co-operative. It does not fit a purely commercial ISP category, which is why any single label here should be held loosely.
Interesting
- Kyoto's research-and-industry councils were also behind the creation of a Kyoto internet exchange, and this AS is a survivor of that same 1990s effort to give a city its own network infrastructure rather than depending on Tokyo.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
