Summary

Hokuden Information System Service Co., Ltd. (FITWeb)

Japan · AI-generated

isp residential eyeball legacy

FITWEB is Hokuden Information System Service Co., Ltd., based in Toyama City and part of the Hokuriku Electric Power group. It runs FITWeb, a consumer and business internet service for the Hokuriku region of Japan.

What it's used for

  • Roughly 68,000 addresses across twenty prefixes, plus 2404:200::/32 in IPv6. JPNIC records the allocations directly to the company, the oldest dating to 2003.
  • Reverse DNS lands on fitweb.or.jp: sequentially numbered subscriber pools such as NNN-NNN-NNN-NNN.dwst.fitweb.or.jp, alongside a handful of named servers like tymwsv01.fitweb.or.jp — tym for Toyama.
  • Beyond access, the company is the Hokuriku Electric group's IT integrator, and part of the space carries corporate and hosted systems.

Notable

  • An eyeball network despite an unpromising corporate name. Hokuden here abbreviates Hokuriku Electric Power, not Hokkaido Electric — an easy misread, since both utilities are commonly shortened the same way in Japanese.
  • The group's other network, HTNet (AS7668), is the carrier; FITWeb sits on the IT-services side. They share adjacent address space in 210.166.0.0/19, which is a reliable hint that they are the same corporate family.

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 1,781 prefixes, as published 2026-10-16. 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.
