Helsinki · Finland
PeeringDB records eight exchanges in Helsinki holding 268 participant entries between them, plus 12 colocation facilities with 142 network presences. PITER-IX Helsinki is the best connected at 126 participants, ahead of FICIX 2 (Helsinki) at 60. An address that geolocates to Helsinki tells you where an operator registered the block, not where a device sits.
Internet exchanges in Helsinki
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.

What a Helsinki IP address tells you
Helsinki holds most of the Finnish peering that PeeringDB records. PITER-IX Helsinki has 126 participants, more than twice FICIX 2 (Helsinki) at 60, and the other six exchanges each sit between 6 and 17 participants. Colocation carries a similar weight, with 12 facilities and 142 network presences, the Digita Helsinki Pasila Broadcasting Tower highest at 54 networks and the Telia Helsinki Datacenter next at 26. All three mobile carriers in the registry peer on FICIX 2: Elisa on AS719, Telia on AS1759 and DNA on AS16086.
An address that resolves to Helsinki need not be a device in Helsinki. An operator announces a block from a registry record that carries one postal address, often an administrative office, and geolocation databases copy that published location onto every address in the range. Mobile access widens the gap again, because Elisa, Telia and DNA hand subscriber sessions to the public internet through a small number of gateways. A handset several hundred kilometres away can therefore appear on a block whose registered city reads Helsinki.
Anyone checking a specific address gets more from the origin ASN and the netname on that prefix than from the city label. AS719, AS1759 and AS16086 identify the Finnish mobile carriers named in the registry, and a prefix originated by one of them behaves as mobile access whichever city a database prints. A prefix originated by a network that appears only inside Equinix HE3 or the Telia Helsinki Datacenter reads as hosting instead. The 142 network presences here describe where networks meet each other, not where their customers are.
Mobile carriers in Finland
A mobile address in Helsinki is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchanges are in Helsinki?
PeeringDB lists eight: PITER-IX Helsinki with 126 participants, FICIX 2 (Helsinki) with 60, Equinix Helsinki and the two Netnod Helsinki MTU9K peering LANs with 17 each, IXP FI HEL with 15, DE-CIX Helsinki with 10, and the FICIX 2 IPv6 MTU 9000 LAN with 6.
Do Finnish mobile carriers peer in Helsinki?
Yes. FICIX 2 (Helsinki) records the mobile ASNs of all three carriers in the registry, Elisa (AS719), Telia (AS1759) and DNA (AS16086). Telia also appears on the FICIX 2 IPv6 MTU 9000 LAN. Peering at an exchange says where a network exchanges traffic, not where its subscribers are.
Does an IP that geolocates to Helsinki mean the device is there?
No. Geolocation databases follow the address an operator published in its registry record, and Finnish mobile networks route subscriber traffic through a few gateways. A Helsinki result is consistent with a device anywhere the operator serves, so read the origin ASN and prefix netname before drawing a conclusion.
