Summary
Fujitsu (InfoWeb)
isp residential eyeball legacy
INFOWEB is Fujitsu Limited's consumer internet service, one of Japan's early dial-up and broadband ISPs. The InfoWeb brand later folded into the @nifty service.
What it's used for
- Consumer internet access for subscribers across Japan.
Notable
- A large eyeball access network (over a million IPv4 addresses), serving end users rather than acting as a hosting or transit provider. The low AS number reflects an early Japanese-internet allocation.

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 2026-10-17. 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.
