Tampere · Finland
PeeringDB records one exchange in Tampere, TREX Tampere (Tampere Region Exchange), with 25 participants, and three colocation facilities holding 32 network presences. TREX is the only exchange the registry lists in the city. An address that geolocates to Tampere reports an operator's own published location for the block, not the position of a device.
Internet exchanges in Tampere
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.

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 |
|---|---|---|
| Tampere Hallituskatu 14 | 15 | Hallituskatu 14 |

What a Tampere IP address tells you
TREX Tampere, the Tampere Region Exchange, is the only exchange PeeringDB lists in the city, and its 25 participants account for every exchange participant recorded here. Colocation holds slightly more, with three facilities and 32 network presences: Tampere Hallituskatu 14 at 15 networks, Elisa Tampere Nalkala at 11 and Glesys Tampere 1 at 6. Two of the country's mobile carriers appear on TREX, Elisa on AS719 and Telia on AS1759. The registry has no entry for DNA's mobile ASN at this exchange.
An address that geolocates to Tampere can belong to a device far from it. Operators announce blocks from a registry record with one address attached, and geolocation databases repeat that value for every address in the range. Finnish mobile traffic leaves through a limited set of gateways, so the city attached to a subscriber address describes the gateway's paperwork rather than the handset. With only 25 exchange participants and 32 facility network presences in Tampere, a Tampere label on a large block is more likely inherited than measured.
Reading the origin ASN and the netname on the exact prefix answers more than the city field. AS719 and AS1759 identify carriers that peer here, AS16086 identifies DNA, whose mobile ASN the registry does not record at TREX, and any of the three can originate a prefix that a database maps to Tampere. If the netname points at a colocation customer at Tampere Hallituskatu 14 or Elisa Tampere Nalkala, the address is a hosted one rather than mobile access.

Questions
Which internet exchanges are in Tampere?
Just one, TREX Tampere, listed in PeeringDB under the long name Tampere Region Exchange, with 25 participants. The city also has three colocation facilities, Tampere Hallituskatu 14, Elisa Tampere Nalkala and Glesys Tampere 1, which together record 32 network presences.
Do Finnish mobile carriers peer in Tampere?
Two of the three do, by the registry's account. Elisa (AS719) and Telia (AS1759) appear on TREX Tampere. DNA (AS16086) has no recorded mobile presence at the exchange, which means PeeringDB holds no entry for it there, not that DNA has no traffic through the city.
Does an IP that geolocates to Tampere mean the device is there?
No. The result comes from the location an operator registered for the address block, and mobile sessions in Finland exit through a small number of gateways. Check which ASN originates the prefix and what the netname says before treating a Tampere result as a physical position.
