France-IX Paris has the most participants at 452, ahead of Equinix Paris at 241, and the registry counts 37 colocation facilities holding 1,252 network presences.

Internet exchanges in Paris
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 Paris IP address tells you
Paris peering concentrates in two exchanges. France-IX Paris counts 452 participants and Equinix Paris counts 241, with BGP.Exchange - Paris third at 64 and everything else well below that, from SFINX at 24 down to France-IX Paris Essentiel at 6. More network presence sits in colocation than on the exchange fabrics themselves, with 37 facilities holding 1,252 presences between them, 360 of those in Telehouse - Paris 2 (Voltaire - Léon Frot) and another 279 across Equinix PA2 and PA3. Bouygues Telecom (AS5410) and SFR (AS15557) both appear on the France-IX Paris and Equinix Paris participant lists.
An address that geolocates to Paris need not reach hardware in Paris. Operators announce blocks from a registry record that carries one administrative address for the whole allocation, and a French mobile network routes subscriber traffic out through a small number of gateways, so a handset anywhere in the country can appear behind an address anchored to the city. Geolocation databases copy what the operator publishes, and because so many French allocations name Paris on paper, the city collects addresses whose actual users are somewhere else entirely.
Someone checking an address learns more from the origin ASN than from the city string. Look up which ASN announces the specific prefix, then read the netname on the most specific inetnum rather than on the parent block. A prefix originated by one of the French mobile ASNs (3215, 5410, 15557) tells you the traffic is mobile and says nothing about the street. A prefix originated by a colocation tenant points at one of the 1,252 network presences PeeringDB counts in the city's facilities.

Questions
Which internet exchanges are in Paris?
PeeringDB lists nine. France-IX Paris has 452 participants and Equinix Paris has 241, followed by BGP.Exchange - Paris at 64, SFINX at 24, nine - six in Paris at 18, ERA-IX Paris at 14, 1-FR FREE at 12 and France-IX Paris Essentiel at 6. Association HwHost records no participants.
Do French mobile carriers peer in Paris?
Two of the three in the carrier registry do. Bouygues Telecom (AS5410) and SFR (AS15557) sit on the participant lists for France-IX Paris and Equinix Paris, and SFR is also on SFINX. Orange's mobile ASN 3215 appears on no Paris exchange list, which does not rule out private interconnection.
Does an IP that geolocates to Paris mean the device is there?
No. The city label comes from the operator's registry record for the address block, not from the device using it. Mobile traffic leaves through a handful of gateways, so a subscriber elsewhere in France can carry a Paris address. Check the origin ASN and the netname on the exact prefix.
