Internet exchanges in Stockholm
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 Stockholm IP address tells you
Stockholm's peering weight sits with Netnod, whose GREEN and BLUE MTU1500 LANs carry 190 and 180 participants. STHIX - Stockholm follows at 84 and SONIX Stockholm at 80, while the two Netnod MTU4470 LANs hold 77 each and DE-CIX Stockholm has 3. Colocation runs just as deep, with 21 facilities recording 469 networks between them, 128 of those at Digital Realty Stockholm STO1-6 and 118 at Equinix SK1 in Bromma. Both Netnod MTU1500 LANs flag nine carrier ASNs and SONIX Stockholm five, though the entry lists no Swedish mobile operator ASNs of its own.
An address that geolocates to Stockholm is an address an operator announced from a registry record, and that record carries an administrative location rather than the position of a handset or a server. Mobile traffic leaves through a small number of gateways, so a subscriber elsewhere in Sweden can appear on a block whose paperwork reads Stockholm. Geolocation databases mostly copy the operator's own published location, which is why one city name repeats across wide parts of a network that reaches far beyond it.
Anyone checking a Stockholm address is better off reading the origin ASN and the netname on the specific prefix than the city label. A prefix originated by a mobile network and a prefix originated by a hosting company in one of the 21 facilities here carry the same city name and mean different things. The exchange numbers on this page describe where networks meet each other in Stockholm, not where any individual address is being used.
Questions
Which internet exchanges are in Stockholm?
PeeringDB lists ten. Netnod runs four peering LANs, GREEN and BLUE at MTU1500 with 190 and 180 participants and both MTU4470 LANs at 77. STHIX - Stockholm has 84, SONIX Stockholm 80, SOLIX 50 and 18 on its two LANs, Equinix Stockholm 18 and DE-CIX Stockholm 3.
Do Swedish mobile carriers peer in Stockholm?
The registry does not answer that directly. Both Netnod MTU1500 LANs flag nine carrier ASNs, SONIX Stockholm five and STHIX - Stockholm three, but no Swedish mobile operator ASNs are listed against this entry, so which of those carriers are mobile networks is not recorded here.
Does an IP that geolocates to Stockholm mean the device is there?
No. The city label comes from the operator's registry record for the address block and from geolocation databases that copy it. A block registered in Stockholm can be used by equipment or subscribers anywhere the operator reaches, and the record is not updated per device.
