Summary
AI3 - WIDE Project
education research legacy
AI3 is the Asian Internet Interconnection Initiatives network, an international research testbed run by Japan's WIDE Project.
What it's used for
- Research and education networking for the AI3 consortium, which links universities and research institutes across Asia.
- AI3 was established in 1995 by the WIDE Project to accelerate internet development in Asia, with hub stations in Japan (Keio University and NAIST).
Notable
- AI3 is unusual among research networks in that its testbed was built on satellite links (Ku-band transponder capacity) rather than terrestrial fibre, specifically to reach partner sites in Southeast Asia.
- Research topics carried over the testbed have included IPv6, web caching and replication, and multimedia communication.
Interesting
- The WIDE Project is one of the foundational forces of the Japanese internet, and AI3's satellite design also made it useful for restoring connectivity after disasters, where terrestrial paths are the first thing to fail.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,772 prefixes, as published 2026-10-15. 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.
