About this network

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.
