Geneva · Switzerland
PeeringDB records one exchange in Geneva, CIXP, the CERN Internet eXchange Point, with 45 participants, and two colocation facilities holding 62 network presences. All three Swiss mobile carrier ASNs peer at CIXP. An address that geolocates to Geneva reflects an operator's registry entry rather than a device standing in the city.
Internet exchanges in Geneva
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 |
|---|---|---|
CIXP CERN Internet eXchange Point | 45 |
Exchange records: PeeringDB.
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 |
|---|---|---|
| Equinix GV1 - Geneva, City | 35 | Rue de la Confédération 6 |
| Equinix GV2 - Geneva, West | 27 | Route du Bois-des-Fréres 46 Le Lignon |
What a Geneva IP address tells you
Geneva has one exchange in PeeringDB, CIXP, the CERN Internet eXchange Point, with 45 participants, and that is the whole of the city's peering count. More network presence sits in colocation than on the exchange fabric: Equinix GV1 holds 35 networks and Equinix GV2 holds 27, 62 between the two facilities. Mobile peering is well represented for a city this size, because CIXP shows the mobile ASNs of Swisscom (AS3303), Sunrise (AS6730) and Salt (AS15796) on its participant list.
Carrier peering in a city does not mean a labelled address belongs to a device there. An operator announces its address blocks against a registry record that carries one location for the whole company, and Swiss mobile networks route subscriber traffic out through a handful of gateways rather than out of each town. Geolocation databases copy the operator's published location, so blocks used across the country can resolve to Geneva, and blocks used in Geneva can resolve somewhere else entirely.
For a specific address, look at the origin ASN and the netname on the prefix that contains it. A prefix originated by one of the three mobile ASNs peering at CIXP is mobile access regardless of the city printed against it. A prefix held by a network with space in Equinix GV1 or GV2 is hosting. The registry record behind the prefix names the holder and its own address, which is the source most geolocation databases are reading in the first place.
Mobile carriers in Switzerland
A mobile address in Geneva 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 Geneva?
One. PeeringDB registers CIXP, the CERN Internet eXchange Point, in Geneva with 45 participants. The city also has two colocation facilities on record, Equinix GV1 with 35 networks and Equinix GV2 with 27.
Do Swiss mobile carriers peer in Geneva?
Yes. CIXP lists the mobile ASNs of Swisscom (AS3303), Sunrise (AS6730) and Salt (AS15796) among its 45 participants, so all three Swiss mobile operators in the carrier registry exchange traffic at the Geneva exchange.
Does an IP that geolocates to Geneva mean the device is there?
No. The city comes from the location an operator published for its address block, not from the connection. Mobile blocks cover a national network and leave through a few gateways, so a Geneva label can sit on a subscriber anywhere in Switzerland.
