Summary
JPIX (Japan Internet Xing)
ixp legacy
JPIX — Japan Internet Xing Co., Ltd., the operator of the JPIX internet exchange. Launched in November 1997 as Japan's first commercial IX, backed by a consortium that included KDD, NEC, Fujitsu and Sony.
What it's used for
- Running the JPIX exchange fabrics (Tokyo, Osaka and other sites) where Japanese and international networks peer with one another.
- JPIX's own infrastructure: route servers, looking glasses, DNS, management and the company's corporate services.
Notable
- This is IXP infrastructure, not a network with users. Its ~1,500 IPv4 addresses carry routers, route servers and management hosts — rDNS resolves to names like
gw.jpix.ad.jp,ns1.jpix.ad.jpandbb-fwfirewall interfaces. - The exchange's peering LAN prefixes are deliberately not routed on the global internet, so the traffic JPIX actually carries never appears in this AS's announcements. Address count says nothing about its importance.
- An IXP has no honest bucket in a hosting/eyeball/transit taxonomy: it is a meeting point, not a provider. Treat it as infrastructure, as with AS4641 (HKIX) and AS5459 (LINX).
Interesting
- The company kept the JPIX brand but is registered as "Japan Internet Xing" — the crossing/exchange pun survives the rename.

Reputation
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 1,783 prefixes, as published 2026-10-20. 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.
