Fukuoka · Japan
PeeringDB records three internet exchanges in Fukuoka and 54 peering records in total. BBIX Fukuoka is the best connected at 20 participants, with JPNAP Fukuoka at 19 and JPIX FUKUOKA at 15. Colocation is thin, at 14 network presences across two facilities. A Fukuoka IP address shows an operator's registry entry rather than a device sitting in the city.
Internet exchanges in Fukuoka
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.
| Exchange | Participants | Registry carriers peering |
|---|---|---|
BBIX Fukuoka BroadBand Internet eXchange Fukuoka | 20 | none in the registry |
JPNAP Fukuoka | 19 | none in the registry |
JPIX FUKUOKA | 15 | none in the registry |

Colocation facilities
Buildings where networks put equipment. The network count is how many PeeringDB members list a presence there, which shows where capacity in the city sits.
| Facility | Networks present | Address |

| AT TOKYO (QC1 QTnet Fukuoka(QD3)) | 0 | , |
What a Fukuoka IP address tells you
Fukuoka carries a small, even set of exchanges. BBIX Fukuoka has 20 participants, JPNAP Fukuoka 19 and JPIX FUKUOKA 15, which is 54 peering records for the city. Colocation is thinner still, with 14 network presences in two facilities, all of them at QTnet Fukuoka Data Center 3 (QD3); the AT TOKYO listing at the same QTnet site records no networks. Networks reaching Fukuoka mostly do so through the three regional exchanges rather than through a dense colocation floor.
The carrier registry for Japan lists no mobile operator ASNs, and none of the three Fukuoka exchanges records a carrier ASN among its participants. An address that geolocates to Fukuoka is telling you what an operator wrote in a registry record for that block. Operators announce blocks from wherever their routing puts them, and mobile traffic exits through a small number of gateways. Geolocation databases copy the location an operator published, so the city label can outrun the equipment by a long way.
Someone checking a Fukuoka address should look at the origin ASN and the netname on the specific prefix, then ask whether that ASN appears in the city at all. With 54 peering records and 14 facility presences on the books, most networks that serve users here have their real interconnection somewhere else, and the registry entry is the only thing tying the address to Fukuoka.
Questions
Which internet exchanges are in Fukuoka?
Three. BBIX Fukuoka has 20 participants, JPNAP Fukuoka 19 and JPIX FUKUOKA 15, giving the city 54 peering records. All three are regional branches of exchange operators that also run much bigger fabrics elsewhere in Japan.
Do Japanese mobile carriers peer in Fukuoka?
Not according to this data. None of the three Fukuoka exchanges records a carrier ASN among its participants, and the Japanese carrier registry used here lists no mobile operator ASNs, so the answer is that the registry is silent.
Does an IP that geolocates to Fukuoka mean the device is there?
No. The label comes from an operator's own published location for the block, and Fukuoka holds only 14 network presences across two facilities. The address tells you which network registered it, and where the device sits is a separate question the geolocation record does not answer.
