Summary

Hokkaido Telecommunications Network Co., Inc. (HOTnet)

Japan · AI-generated

enterprise isp legacy

HOTNET is Hokkaido Telecommunications Network Co., Inc., trading as HOTnet — the telecoms arm of the Hokkaido Electric Power group, based in Sapporo and operating some 20,000 km of its own optical fibre across Hokkaido.

What it's used for

  • About 35,800 addresses across six prefixes, plus 2001:398::/32 in IPv6.
  • Reverse DNS is uniformly NNN.NNN.NNN.NNN.hotcn.ne.jp — plain address-derived names on the company's own domain, with named infrastructure such as ns.hotcn.ne.jp. That is generic assigned space, not a labelled consumer access pool: there are no pppoe-, dsl-, dyn- or pc- style markers of the kind the other utility ISPs publish.
  • The service portfolio is corporate: leased lines and dark fibre, wide-area Ethernet, data-centre services, and broadband access sold largely to businesses and public bodies across the island's municipalities.

Notable

  • Classified as business, not eyeball, and this distinction matters. HOTnet is the one utility-telecom in this cohort that did not build a mass consumer fibre brand — unlike QTnet's BBIQ (AS7679) or Enecom's MEGA EGG (AS7670) — so its addresses tend to sit at company offices and institutions rather than in homes.
  • Taking "power-company telecom in Japan" as shorthand for "residential ISP" would get this one wrong.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
