Summary
QTnet, Inc.
isp residential eyeball fiber legacy
QTNET is QTnet, Inc., the telecoms subsidiary of the Kyushu Electric Power group and the operator of BBIQ, the main independent fibre-broadband service across Japan's Kyushu island.
What it's used for
- Roughly 761,000 addresses across thirty-six prefixes, plus
2001:348::/32in IPv6 — by a wide margin the largest network in this range of AS numbers. - Reverse DNS is overwhelmingly consumer: nearly every prefix sampled resolves to
NN-NNN-NNN-N.ppp.bbiq.jpor.ppps.bbiq.jp, sequential per-subscriber names on the BBIQ access network. A minority of space carries acyberhome.ne.jpISP brand and delegated customer sub-blocks.
Notable
- A textbook eyeball network. Addresses in it belong to households and small businesses in Fukuoka, Kumamoto, Nagasaki, Kagoshima and the rest of Kyushu. Nothing here should be read as hosting or datacentre space, despite the AS also carrying the company's data-centre business on a small share of its prefixes.
- The
ppp.label in the rDNS is a fossil: subscribers are on fibre, but the sessions are still PPPoE, so the naming convention survived the technology it described.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
