Malmö · Sweden
PeeringDB records one exchange in Malmö, Sweden, SONIX Malmo, with 8 participants. The city's weight is in buildings instead, seven facilities holding 53 networks, 27 of them at Malmö Västergatan 4 / Stortorget. An address that geolocates to Malmö reflects the operator's registry record for the block, not the location of the device using it.
Internet exchanges in Malmö
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.

What a Malmö IP address tells you
Malmö's recorded capacity sits in colocation rather than at an exchange. SONIX Malmo is the only exchange in the entry and has 8 participants, while seven facilities hold 53 networks between them, 27 at Malmö Västergatan 4 / Stortorget, 10 at GlobalConnect Malmö and 7 at 31173 DC Malmö Scheelegatan. Krossverksgatan 13a, Malmö/B and Bahnhof Sparven account for the rest, and Global Crossing Malmo is listed with no networks. No carrier ASN is flagged at SONIX Malmo, and no Swedish mobile operator ASNs appear against the city.
An address that geolocates to Malmö is an address an operator announced from a registry record, and that record holds an administrative location rather than a device position. Mobile traffic leaves through a small number of gateways, so an address block filed in Malmö can carry subscribers well outside it. Geolocation databases mostly copy whatever location the operator published, which is why a lookup can return Malmö for a network whose routing and equipment are somewhere else entirely.
The useful checks are the origin ASN and the netname on the specific prefix. With one exchange at 8 participants and 53 networks spread over seven buildings, most of what carries a Malmö label is a network present in a facility rather than an address handed to a device in the city. The prefix record says which of the two it is.
Questions
Which internet exchanges are in Malmö?
One is listed, SONIX Malmo, part of the Sweden Open Network Internet eXchange, with 8 participants. The other Malmö records in PeeringDB are colocation facilities rather than exchanges, seven of them holding 53 networks in total.
Do Swedish mobile carriers peer in Malmö?
The registry does not record it. SONIX Malmo flags no carrier ASNs, and no Swedish mobile operator ASNs are listed against this entry, so mobile peering in the city is unrecorded here rather than confirmed or denied.
Does an IP that geolocates to Malmö mean the device is there?
No. The city comes from the operator's registry record for the address block, which geolocation databases then repeat. A block registered in Malmö can be used across a wider area, and nothing in the record ties it to one street or building.
